1X+8X=90
9X=90
X=10
so one of them is 10 and the other one is 8 times 10 which become 80
Answer:
test? :/
Step-by-step explanation:
Distance formula is SquareRoot of (x2-x1)^2 + (y2-y1)^2
= SQRT( (8-0)^2 + (-8-7)^2 )
=SQRT(64 +225)
=SQRT(289)
= 17
Answer:
c = 196
Step-by-step explanation:
To obtain a perfect square trinomial
Add ( half the coefficient of the x- term )² to x² + 28x
x² + 2(14)x + (14)², that is
x² + 28x + 196
= (x + 14)² ← a perfect square
I think you mean length times width, which is more simply written as lw.
