Answer:
4(8+n)
(n×8) + (n×4)
8(n+4)
(n×8) + (n²)
Step-by-step explanation:
just very basically calculate or transform the expressions. pay attention to what is a multiplication, and what is an addition (sometimes the brackets try to suggest something else than what is actually there).
Volume formula: V = hwl
V = 3*3*4
V = 9*4
V = 36
Therefore, the volume is 36cm³
Best of Luck!
Answer:
I get x = 16/7 ft or about 2.29 ft for the width and 4.29 ft for the height.

Answer:
-127
Step-by-step explanation:
u(x)=2x-2
w(x)= -2x^2+1
w(u(5))=?
---------
u(5)= 2*5-2= 8
W(8)= - 2*64+1= -127
