Use the distributive property to remove the parentheses. -7^2+4(-7)-4

1 answer:

6 0

-7^2+4(-7)-4

49-28-4

17

My thought process goes as follows

I went -7x-7 which is 49 (negative x negative is equal to a positive)

4(-7) means 4x-7

Then added them all together

Answer is 70degree because if angle 1 is 70 then angle 2 also will be the same then it means even angle 3 will be 70.

Fill in the other coordinate for the line 2x - 5y = 11: (4, )

Katen [24]

2x - 5y = 11. (4, a). x = 4, y = a

Substituting into 2x - 5y = 11

2(4) - 5(a) = 11

8 - 5a = 11

-5a = 11 - 8

-5a = 3

a = 3/-5 = -3/5 =- 0.6

Other coordinate = -3/5 = -0.6
