-7*-5=35
add your terms together in standard form
answer is C
Step-by-step explanation:
Area = length × width
72 = 9 × width
8 = width (9 × 8 = 72)
pertinter = length + width + length + width
= 9 + 8 + 9 + 8
perimeter = 34m

Answer:
<h2>3240 it's not a perfect cube.</h2><h2>The smallest number should 3240 be multiplied so that the product is a perfect cube is 15² = 225.</h2>
Step-by-step explanation:
3240 is a perfect cube if 3240 = n³ (n ∈ N).
Use the Prime Factorization:
Used:
Slope of the line
(8-6)/(2-4)
2/-2
-1
General equation of the line
y = mx + c
m=-1
so
y = -x + c
if it passes through (2,8)
8 = (-1*2) + c
8 = -2 + c
c = 10
so the equation is
y = -x + 10
