28x+40 add up all of the x’s and then all the normal numbers
Answer:
40 in
Step-by-step explanation:
For a width of w, the length is 3w and the area and perimeter are ...
A = LW = (3w)(w) = 3w^2
P = 2(L+W) = 2(3w +w) = 8w
We are given the area, so we can find w to be ...
75 in^2 = 3w^2
25 in^2 = w^2 . . . . . divide by 3
5 in = w . . . . . . . . . square root
Then the perimeter is ...
P = 8w = 8(5 in) = 40 in
Answer:
option d
Step-by-step explanation:
(-4ab)^3 = (-4ab)(-4ab)(-4ab) = -64a^3b^3 (option d)
I hope this helped, please give brainliest if this is correct! Thank you!
Sales tax 8%
8/100 x $39.50
= $3.16
Textbook price + Sales Tax =
$39.50 + $3.16
=$42.66
Discount 8%
8/100 x $42.66
= $3.4128
Textbook price - Discount
= $42.66 - $3.4128
=$39.2472
