Answer:
All polygons have straight lines
Step-by-step explanation:
5(2x - 8) + 15 = -15
-15 -15 subtract 15 from each side
5(2x - 8) = -30
÷5 ÷5 divide both sides by 5
2x - 8 = -6
+8 +8 add 8 to each side
2x=2
÷2 ÷2 divide both sides by 3
x = 1
Checking:
5(2(1)-8) + 15 = -15
5(-6) + 15 = -15
-30 + 15 = -15
-15 = -15 Correct! x=1
Aec= 40
Explanation because it’s a 90 degree angle and dea = 50
So 90-50=40

X=
with x+6=10
yo try to move everything to the opposite side of the X.
so:
adding equals subtracting. + = -
subtracting equals adding. - = +
dividing equals multiplaying. ÷ = ×
and multiplaying equals to dibidion. × = ÷
