Answer: angle 7 = 80 degree and angle 8 = 100 degree
The angle right above 4x is equal to x
and 4x + x = 180
5x = 180
/5 /5
x = 36
la respuesta que encontré yo fue la c
(₋4)²
how i got it -
1st i used the sum-product pattern
x² - 8x + 16
x² -4-4+16
then, found the common fact from the two pairs
x² - 4 - 4 + 16
(-4) - 4(-4)
rewrite in factored form
(x-4)-4(-4)
(-4) (-4)
combine to a square
(-4) (-4)
