Answer:
m=21 and n=21
Step-by-step explanation:
In order to maximize the area of the rectangle, you want the two side lengths to be as equal to each other as possible.
In this case, we get that 2m+2n=84, so m+n=42. In our case, m and n can equal each other, so that gives us the maximum area of 441
Proof that this works:
If we had other dimensions, like m=20 and n=22, the area would be 440, slightly less than 442. If m=19 and n=23, the area becomes 437, which is even further off from 441.
Answer:
Answer :
( -4x3 + x^2y - xy2) = -4x^3 + x^2y - xy^2
( 3x3 - xy2 + 5x^2y) = 3x^3 - xy^2 + 5x^2y
( 7xy2 + 3y3) = 7xy^2 + 3y^3
Step-by-step explanation:
Answer:
C. 2x + 6
Step-by-step explanation:
After doing synthetic division (see attached), you get 2, 6, and 0, corresponding to the answer 2x + 6.
Answer:
yes she can
Step-by-step explanation:
y = 1.4(t) + 3
y = 1.4(15) + 3
y = 21 + 3
y = 24
since the total is 24, which is less than 25, she can talk for 15 minutes.
