Find the value of x.
Answer:
x= 20
Step-by-step explanation:
The total amount of degrees in a triangle is 180. The equation we can pull from this is x+x+30+110= 180. Now we can simplify and combine like terms. x+x= 2x. 30+110 is 140. Now move the constant, 140 to the right. 180-140 is 40. Lastly, divide x and 40 by 2 to get the final answer of 20.
Find the product of (x + 3)(x - 3).

Which equation is true? 9x2 – 25 = (3x – 5)(3x – 5) 9x2 – 25 = (3x – 5)(3x 5) 9x2 – 25 = –(3x 5)(3x 5) 9x2 – 25 = –(3x 5)(3x – 5).
Answer:
9x² - 25 = (3x - 5)(3x + 5)
Step-by-step explanation:
(a + b)(a - b) = a² - ab + ab - b² = a² - b²

Bobby has a party while his parents are away for the weekend. Bobby estimated that if his 9 friends hep him to clean the house, they will finish in time if they start 8 hours before his parents return. But after only two hours of cleaning, Bobby's parents call and say they are just two hours from home. How many more friends does Bobby need to call to help finish cleaning in time.
Bobby will need additional 20 friends to help finish cleaning in time.
Rate at which Bobby and his 9 friends are workingThe rate at which Bobby and his 9 friends are cleaning the house is determined as follows;
10 person ------> 8 hours
1 person -------->?
= 10 x 8 = 80 hours/person
When the parents are 2 hours from the house, Bobby will more friends working at the same rate to complete it in 2 hours time.
During this period Bobby and his friends have worked for 2 hours remaining 6 hours.
New rate;
10 person ------> 6 hours
1 person -------->?
1 person = 10 x 6 hrs = 60 hours per person
Total persons that will do the same work in 2 hours2 = 60/x
x = 60/2
x = 30 persons
Thus, Bobby will need additional 20 friends to help finish cleaning in time.

Find the measure of each angle in the problem. MG contains point T.
A. 100 and 80
B. 95 and 85
C. 50 and 40
D. 60 and 120
Answer:
A
Step-by-step explanation:
the angles are adjacent angles on a straight line and sum to 180°, so
5x + 4x = 180
9x = 180 ( divide both sides by 9 )
x = 20
then
∠ MTQ = 5x = 5 × 20 = 100°
∠ GTQ = 4x = 4 × 20 = 80°

Four circles, each with a radius of 2 inches, are removed from a square.
Four circles, each with a radius of 2 inches, are removed from a square. What is the remaining area of the square?
(16 – 4π) in.2
(16 – π) in.2
(64 – 16π) in.2
(64 – 4π) in.2
Given:
Given that the radius of the circle is 2 inches.
We need to determine the area of the remaining square.
Area of a square:
Given that each circle has a radius of 2 inches.
Then, the diameter of each circle is 4 inches.
Hence, the side length of the square is 2 × 4 = 8 inches.
The area of the square is given by
[tex]A=s^2[/tex]
[tex]A=8^2[/tex]
[tex]A=64[/tex] [tex]in^2[/tex]
Thus, the area of the square is 64 square inches.
Area of the four circles:
The area of one circle is given by
[tex]A=\pi r^2[/tex]
Substituting r = 2, we have;
[tex]A=4\pi[/tex]
Thus, the area of one circle is 4π in²
The area of 4 circles is 4 × 4π =16π in²
Hence, the area of the 4 circles is 16π in²
Area of the remaining square:
The area of the remaining square is given by
Area = Area of the square - Area of four circles.
Substituting the values, we get;
[tex]Area=64-16\pi[/tex]
Thus, the area of the remaining square is (64 - 16π) in²
Hence, Option c is the correct answer.

Solve the equation. 4y = 12
Answer:
y = 3Step-by-step explanation:
Given equation:
4y = 12To solve the equation, the L.H.S must be equivalent to the R.H.S. To prove that L.H.S is equivalent to R.H.S, we have to know the value of "y".
The value of the y variable can be found by isolating the variable from its coefficient. In this equation, the y-variable can be isolated by dividing both sides by four. This cancels the coefficient, isolating the y-variable on one side of the equation.
⇒ 4y = 12⇒ 4y/4 = 12/4 (Dividing both sides by 4)Once the y-variable has been isolated, we can simplify the other side of the variable. The expression/variable/number obtained, on the other side of the equation, is the value of the y-variable.
⇒ y = 12/4 (Isolating the y-variable)⇒ y = 3 (Simplifying the R.H.S)Therefore, the value of y is 3.

Divide the shape into two rectangles (see attached image)
Area of a rectangle = width × length
Area of rectangle 1
⇒ area = 2 × 3

Area of rectangle 2
⇒ area = (5 - 3) × 7

A forest fire has been burning for several days. The burned area, in acres, is given
the equation y = (4, 800) • 2d, where d is the number of days since the area of the
fire was first measured.
Complete the following table:
Answer:
you gotta show a picture of the table in order for us to know what's missing from it
When d = -1, the value of y is 300 acres means that the area burned in the fire was 300 acres. When d = -3, the value of y is 1.17 acres means that the area burned in the fire was only 1.17 acres three days
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
we can use the given equation y = (4,800)2^d and substitute the values of d in the table to get the complete table.
Now the equation y = (4,800)2d for d when y = 4,800 and then subtract 7 from that value.
(4,800)2d = 4,800
2d = 1
d = 0.5
The fire had burned for 12 hours, before it measured 4,800 acres.
To determine the area the fire had burned a7 days before this measurement, we will then substitute d = -6.5 into the equation:
y = (4,800)2(-6.5) ≈ 0.00025 acres
