First, factor out 5:
5 (x² -x -20)
We need two numbers that add to -1 and multiply to -20. -5 and 4 satisfy this.

Solve<br> 11x-6y=3 ; 5x-8y=-25
Fiesta28 [93]

Answer: x=3 and y=5

Step-by-step explanation: 11x-6y=3, 5x-8y=-25

11x-6y+6y=3+6y

11x/11=3/11+6y/11

x=3+6y/11

5(3+6y/11)-8y(11)/11

5(6y+3)-88y/11

30y+15-88y/11

88y-30y

58y

11(15-58y)/11=11(-25)

15-58y-15=-275-15

-58y/-58=-290/-58

y=5

x=3+6(5)/11

3+30

33

33/11

x=3

x=3, y=5

Use this idea to find the value of x in the diagram at<br> right. Be sure to show all work.<br> 71°
EleoNora [17]

We have that  the value of x in the diagram at the right is

x=109

From the question we are told

Use this idea to find the value of x in the diagram at  right.

From The diagram  we have a Triangle with its base angles equal

Generally the equation for the Triangle   is mathematically given as

180=2b+y

Where

b=Base angles

Since Angle on a straight line is 90

Therefore

180=71+x

x=109

In conclusion

The value of x in the diagram at the right is

x=109

What is the area of the square? Help me pls
Allushta [10]

Answer and Step-by-step explanation:

First, we need to find out the circumference of the circle.

We know that the circle has a radius of 1, and that we are finding the circumference. We'll use the circumference equation of a circle.

2\pir

<u>Plug in 1 for r.</u>

2\pi (1) = 2\pi = circumference of circle

<u>Now, multiply the answer (the circumference) by 4 to get the perimeter of the square.</u>

<u />2\pi x 4 = 8\pi = perimeter of square

<u>Now, divide the perimeter by 4 to get what the side of the square is.</u>

<u />8\pi ÷ 4 = 2\pi

<u>Now, multiply </u>2\pi<u> by </u>2\pi<u> (side times side) to get the area.</u>

2\pi x  2\pi = 4\pi

The answer is A. 4\pi
