Evaluate the expression | 4b-4| + 3b for b = -2

Hello!

You put -2 in for b

/4(-2) - 4/ + 3(-2)

Multiply

/-8 - 4/ -6

Subtract

/-12/ - 6

Take the absolute value of -12

12 - 6 = 6

The answer is 6

Hope this helps!

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
