Find the value of x in the triangle
Answer:
x =3.
Step-by-step explanation:
This is an isosceles triangle so the 2 sides opposite the equal angles are congruent.
So 3x + 2 = 11
3x = 9
x = 3.
Answer:
49 and 2/3
Step-by-step explanation:
3x+2+18+11=180
3x+31=180
3x=149
x=49 and 2/3
could you use the formula for the surface area of a rectangular prism to find the surface area of a cube explain please help me.
Answer:
You can use our formula for the surface area of a rectangular prism for a cube as well. A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

A circle is centered at the point (-7,-1) and passes through the point (8, 7).
The radius of the circle is
units. The point (-15,
) lies on this circle.
Reset
Next
Answer:
17 units
Step-by-step explanation:
The radius r is the distance from the centre of the circle to a point on it.
To calculate r use the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 7, - 1) and (x₂, y₂ ) = (8, 7)
r = [tex]\sqrt{(8+7)^2+(7+1)^2}[/tex]
= [tex]\sqrt{15^2+8^2}[/tex]
= [tex]\sqrt{225+64}[/tex]
= [tex]\sqrt{289}[/tex]
= 17

If c is a constant such that x^2+100x+c is equal to the square of a binomial, then what is c?
Answer:
c = 2500
Step-by-step explanation:
[tex]x^2+100x + c\\x^2+2\times 50\times x + (50)^2\\=x^2+2\times 50\times x + 2500\\=x^2+100 x + 2500\\equating \: it \: with\: \\x^2+100x + c\\we\; find:\\c = 2500[/tex]
Answer:
c = 2500
Step-by-step explanation:
x² + 100x + c where c = ?
100 x : 100x / 2x = 50
(50)² = 2500

Answer:
[tex]58.91m^2[/tex]
Step-by-step explanation:
(smaller triangle below)
[tex]A=\frac{ab}{2}\\ =\frac{8.6*5.5}{2}\\ =23.65m^2\\\\A=\frac{ab}{2}\\ =\frac{8.6*8.2}{2} \\=35.26m^2[/tex]
(bigger triangle above)
Since you have both triangle, and all lengths you dont need to worry about calculating the square
Add both together
[tex]23.65+35.26\\=58.91m^2[/tex]
Answer:
There’s 2 triangles and 1 rectangle
The formula for the area of a triangle is 1/2 x base x height
The area of the triangle on the left is:
1/2 x 5.5 m x 8.6 m = 23.65 m^2
The area of the triangle on the right is:
1/2 x 8.2 m x 8.6 m = 35.26 m^2
The formula for the area of the rectangle is length x width.
The area of the rectangle is:
8.6 m x 7.6 m = 65.36 m^2
The area of the entire figure = sum of all the areas in the figure
23.65 m^2 + 35.26 m^2 + 65.36 m^2 = 124.27 m^2
Hope this helps! :)

Answer:
7/6
Step-by-step explanation:
7/8 * 4/3
7/2 * 1/3
7/6
Answer:
When you divide a fraction, make the second number the reciprocal. Then multiply them.
So it is
3/4 = 4/3
7/8 * 4/3 = 28/24
28/24 is the answer
Simplified = 7/6 or 1 1/6

Consider triangle DEF. The legs have a length of 36 units
What is the length of the hypotenuse of the triangle
18 units
1872 units
36 units
36/7 units
Answer:
[tex]\large \boxed{36\sqrt{2}\text{ units}}[/tex]
Step-by-step explanation:
Assume ∆DEF looks like the one below.
We can use Pythagoras' Theorem to find the hypotenuse f.
[tex]\begin{array}{rcl}d^{2} + e^{2} & = & f^{2}\\36^{2} + 36^{2} & = & f^{2}\\f^{2} & = & 2 \times 36^{2}\\f & = & \sqrt{2 \times 36^{2}}\\& = & 36\sqrt{2}\\\end{array}\\\text{The length of the hypotenuse is $\large \boxed{\mathbf{36\sqrt{2}}\textbf{ units}}$}[/tex]

Rita pumped 42 gallons of water into her pool. This was done over a period of 6 minutes at a constant Rate. What was the change in the amount of water in the pool each minute
Answer:
7 Gallons every minute
Step-by-step explanation:
We know that a total of 42 gallons of water was pumped for 6 minutes at a constant rate. Constant rate means that it will always pump the exact same amount of water each time. Eince its at a constant rate we just need to find out how much water was poured over the course of a minute, which can be done by dividing 6 (minutes) by 42 (gallons of water) = 7 gallons of water.

Ohhh you wrote 4 on the other post, not 4x.
Okay.
6(x+3)-4x=10
6x+18-4x=10
2x=-8
x=-4
Answer:
The value of [tex]x[/tex]:
[tex]x = -4[/tex]
Step-by-step explanation:
Solve for [tex]x[/tex]:
[tex]6(x+3) - 4x = 10[/tex]
Use Distributive Property:
[tex]6(x+3) - 4x = 10[/tex]
[tex]6x + 18 - 4x = 10[/tex]
Combine [tex]6x[/tex] and [tex]-4x[/tex] together:
[tex]6x + 18 - 4x = 10[/tex]
[tex]2x + 18 = 10[/tex]
Subtract both sides by [tex]18[/tex]:
[tex]2x + 18 - 18 = 10 -18[/tex]
[tex]2x = -8[/tex]
Divide both sides by [tex]2[/tex]:
[tex]\frac{2x}{2} = \frac{-8}{2}[/tex]
[tex]x = -4[/tex]
So, therefore, the final answer is [tex]x = -4[/tex] .

Answer:
x + 6x+10 + x+2 = 180
x = 21
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
x + 6x+10 + x+2 = 180
Combine like terms
8x + 12 = 180
Subtract 12 from each side
8x+12-12 = 180-12
8x =168
Divide each side by 8
8x/8 = 168/8
x =21
Answer:
Step-by-step explanation:
by angle sum property of a triangle ,
x+x+2+6x+10=180
8x =180-12
8x =168
x =168/8
x=21

Answer:
Step-by-step explanation:
$ 86,000 lies in the category $84201 - $ 160725
Tax = 14,382.50+ 24% of the amount over $84,200
Amount over $84,200= 86,000 - 84,200 = $1,800
Tax for the amount $ 1,800 =24% * 1800 = 0.24 * 1800
= $ 432
Tax for the amount $86,000 = 14382.50 + 432
=$ 14814.50
