Answer:
The expression would be 43x + 128
Step-by-step explanation:
43 dollars is multiplied by however many feet is used. Then, the exception(the gate) is added to the charge that is 43x
Answer:
A.−3x^4+2x^2−4x
B.4p^7−10p^5+2p^4
Step-by-step explanation:
A.x(−3x^3+2x−4) then simplify −3x^4+2x^2−4x
B. -2p^3(-2p^4+5p^2-p) then simplify 4p^7−10p^5+2p^4
9514 1404 393
Answer:
18
Step-by-step explanation:
Solve the first for a, then substitute into the second.
a = 27/(5b^2)
Then ...
(27/(5b^2))^2·b = 135
27^2/(5^2·135) = b^3 = 27/125
b = ∛(27/125) = 3/5
a = 27/(5(3/5)^2) = 15
__
The expression of interest is ...
a +5b = 15 + 5(3/5) = 15 +3
a +5b = 18
