Answer:
$22 dollars
Step-by-step explanation:
Add the two numbers. x means one for mathamatics.
No.
When you plug in -6 for x, and 6 for y, like this 5 (-6) + 12 (6) = -15, it does not equal -15, but 42.
5)surface =2(lb*bh*hl)
=2(12*4+4*4+4*12)
=2(48+16+48)
=2(96+16)
=2*112
=224inc^2
6)surfacearea=2*pi*r(r+h)
=2*3.14*2(2+1)
=6.28*2*3
=6.28*6
=37.68m^2
Answer: a. x = 75
z=30
40-10=30
10+10+?=30
30-10-10=10
I'm sorry cuz I don't know how to explain it
