Answer:

Step-by-step explanation:
Distribute (2h − 3k)(h + 5k).
2h^2 + 10hk - 3hk - 15k^2
2h^2 + 7hk 15k^2
Answer:
44%
Step-by-step explanation:
60%-16% the answer is up ahead.
Simple just subtract and u get-74.85
Let

and

be the sides of the rectangle. The perimeter is given to be 500m, so we are maximizing the area function

subject to the constraint

.
From the constraint, we find

so we can write the area function independently of

:

Differentiating and setting equal to zero, we find one critical point:

which means

, so in fact the largest area is achieved with a square fence that surrounds an area of

.
Answer:
yes
Step-by-step explanation:
side 1
(2,8) to (2,2)
8-2 = 6 (length of this side)
side 2
(2,2) to (-4,2)
2-(-4) = 6
side 3
(-4,2) to (-4,8)
8-2 = 6
side 4
(-4,8) to (2,8)
2- (-4) = 6
* note: it doesn't matter the order of subtraction because length can't be negative (so just make sure your answer is positive) , also don't subtract the side that is constant, you will get 0, a side can not be 0 cm
to find the area of a square multiply length by width
6 x 6 = 36
