Which equation could be used to find the value of x in the triangle below?
4x + 10
6x - 10
А
12x + 20 = 180
B
12x = 180
С
12x - 20 = 180
D
8x - 10 = 4x + 10
Answer:
B
Step-by-step explanation:
4x+10+6x-10+2x=180°
4x+6x+2x=180°+10-10
12x/12=180°12
x=15° check :
4x+10+6x-10+2x=180° then x=15°
4*15+10+6*15-10+2*15=180°
60+10+90-10+30=180°
180°=180°
The equation representing the value of x is 12x + 20 = 180
What is a triangle?A triangle is a polygon with three edges and three vertices.
Given that, a triangle having interiors angles, 2x, 4x + 10 and 6x - 10
We know that, the sum of the interior angles of the triangle = 180°
Therefore,
2x + 4x + 10 + 6x - 10 = 180°
12x + 20 = 180°
Hence, the equation representing the value of x is 12x + 20 = 180

An angle measures 21.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
angles 100.6 and 79.4 = 180 degrees
Step-by-step explanation:
supplementary angles add to 180
angles 100.6 and 79.4 = 180 degrees
100.6 -21.20= 79.4
x+ x-21.2 = 180
2x = 158.8
x= 79.4
79.4 + 21.2= 100.6

What is linear equation?A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.
Given linear equation
4(x – 5) + 2x = 9x – 2(4 + 2x)
Step 1: 4x - 20 + 2x = 9x - 8 - 4x
Step 2: 6x - 20 = 5x - 8
Next step is Subtract 6x from both sides.
Step 3: 6x - 20 - 6x = 5x - 8 - 6x
⇒ -20 = -x - 8
Next step is Add 8 to both sides.
Step 4: -20 + 8 = -x - 8 + 8
⇒ -12 = -x
⇒ x = 12
Hence,
To solve the given linear equation , next steps to be followed
1. Subtract 6x from both sides.
2. Add 8 to both sides.

Is the sum of the areas of two smaller squares equal to the area of a large square if the side lengths of the squares are 8 feet, 5 feet, and 3 feet? Note that the area of a square is s2, where s is the side length. Explain.
Answer:
No, the sum of the areas of two smaller squares is not equal to the area of a larger square if the lengths of sides of the squares are 8 feet, 5 feet and 3 feet.
Step-by-step explanation:
WE know that the area of a square is A = s² where s = length of side of the square. Now, since we have squares of varying sides of 8 feet, 5 feet and 3 feet respectively, we want to determine if the areas of the two smaller squares equals that of the larger square. Let A = area of 8 feet side square, A' = area of 5 feet side square and A" = area of 3 feet side square. We want to show if A = A' + A".
Now A = (8 ft)² = 64 ft²
A' = (5 ft)² = 25 ft² and
A" = (3 ft)² = 9 ft²
A' + A" = 25 ft² + 9 ft² = 36 ft²
Since L.H.S = 64 ft²and R.H.S = 36 ft²
So, 64 ft² ≠ 36 ft²
L.H.S ≠ R.H.S
So, the sum of the areas of two smaller squares is not equal to the area of a larger square if the lengths of sides of the squares are 8 feet, 5 feet and 3 feet.
At president bushs inauguration in 2005 the news paper headlines stated there were about 400,000 people in attendance. If the newspaper rounded to the nearest ten thousand, what is the largest number and smallest number of people who could have been there
Answer: Largest = 404999
Smallest = 395,000.
Step-by-step explanation:
Given data:
Number of people in attendance = 400,000
Solution:
If we were to round off to the nearest ten thousand the greatest number we can get would be = 404999.
And following the same principle the smallest number we would be able to get would be = 395000
Therefore, the largest number of people who could have attended the inauguration would be 404999.
And the smallest number of people who could have attended would be 395000.

A thin wire 40 CM long is formed into a rectangle if the width of this rectangle is 8 CM what is length and area
Length of a wire = 40 cm.
Breadth of the rectangle formed = 8 cm.
Find:length and area of rectangle.
Solution:Length of a wire = 40 cm.
A rectangle is made from this wire.
That means,
Perimeter of the rectangle formed = length of the wire.
Also,
Breadth of the rectangle formed = 8 cm.
We know that,
Perimeter of a rectangle = 2(length + breadth).
Let the length of the rectangle be x cm.
Hence,
→ 2(x + 8) = 40
→ 2x + 16 = 40
→ 2x = 40 - 16
→ 2x = 24
→ x = 24/2
→ x = 12
Hence,
Length of the rectangle formed = x = 12 cm.
Now,
We know,
Area of a rectangle =length * breadth
→ Area of the rectangle = (12) * (8)
→ Area of the rectangle = 96 cm²
Therefore, the area of the rectangle formed is 96 cm².
I hope it will help you.

You are given a 14 inch by 8 inch rectangular sheet of metal from which you are to construct a box. You are to cut a length, x, from each corner of the sheet of metal so that you can fold up the sides creating a box. Find the value of x that will yield the maximum volume of the box. Round your solution to the nearest hundredth.
Answer:
x = 1.639 in
Step-by-step explanation:
With these instructions, the length of the box would be (14-2x), the width would be (8-2x), and the height would be x, so the equation for volume would be width*length*height, or
[tex]V=(14-2x)(8-2x)(x)[/tex]
[tex]V=4x^3-44x^2+112[/tex]
Now we solve for dV/dx because we want to find maximum volume
[tex]\frac{dV}{dx} =12x^2-88x+112[/tex]
[tex]\frac{dV}{dx} =4(3x^2-22x+28)[/tex]
Now we let dV/dx equal zero to find critical values
[tex]0=4(3x^2-22x+28)[/tex]
[tex]0=3x^2-22x+28[/tex]
[tex]x=\frac{11+\sqrt{37} }{3}[/tex], [tex]x=\frac{11-\sqrt{37} }{3}[/tex]
Now we see where dV/dx changes signs:
dV/dx changes from positive to negative at [tex]\frac{11-\sqrt{37} }{3}[/tex]
and from negative to positive at [tex]\frac{11+\sqrt{37} }{3}[/tex]
so V(x) has a local maximum when x = [tex]\frac{11-\sqrt{37} }{3} = 1.639[/tex] in

Avi’s dining room measures 124 square feet and is in the shape of a square. Which is the best estimate of the length of one side of the room, to the nearest tenth of a foot?
10.7 feet
10.9 feet
11.1 feet
11.4 feet
Answer:
11.1 feet
Step-by-step explanation:
because the formula for area of a square is A=L^2
so in this situation you would square root the 124 square feet, since all 4 sides are equal lenths
Answer:
The answer is C, 11.1 feet.
Step-by-step explanation:
To figure this out, you would estimate the square root of 124, since a square has sides of equal length. Your estimate would be closest to 11.1. I hope my answer helps, and if it does not, please leave a comment below, so that I can fix it.
