1. identify the property used to find the equivalent expression.
[4+(-2)] +1 = 4+[(-2) + 1]
(9.3) 6 = 6. (9.3)
(a x 3) b = b (a * 3)
x + y + z) = (x + y) + z
2 x (p x q) = (q xp) x 2
(8 + 17) + 18 = 18+ (17 + 8)

idk wbu

step-by-step explanation:

d. you cannot tell because there are no values shown.

the answer is a.

606.0 sq. in.

i got it down.

any line whose slope not equal to -4 does not satisfy these requirements.

step-by-step explanation:

going from (1,2) to (3, -6), x increases by 2 and y decreases by 8.   thus, the slope of a line thru those two points has the slope m = -8/2, or   m = -4.

thus, no line that has a slope different from m = -4 could be appropriate.
