1 is 18
2 is C
hope these work
Answer:
Step-by-step explanation:
A=s^2=64
s=8m
d^2=x^2+y^2, since it is a square x=y=8 then
d^2=2x^2
d^2=2(8^2)
d^2=128
d=11.3
So diagonal is approximately 11m
Answer:
W = 14, L = 18
Step-by-step explanation:
If L = length and W = width, then:
252 = LW
L = W + 4
Substituting:
252 = (W + 4) W
252 = W² + 4W
0 = W² + 4W − 252
0 = (W + 18) (W − 14)
W = -18 or 14
Since W > 0, W = 14. Which means L = 18.

Answer:
5x^2 -55x +150 = 0
Step-by-step explanation:
A root of p means (x-p) is a factor. So, the factored form of the equation you want is ...
5(x -5)(x -6) = 0
5(x^2 -11x +30) = 0 . . . . . multiplying binomials
5x^2 -55x +150 = 0 . . . . applying the leading coefficient
