1/2 *(a+b)-(a-b)²
a=18, b=14
1/2 *(18+14)-(18-14)²=1/2 *(18+14)-(18-14)²= 1/2*32-4²=16-16=0
answer D
answer B
2 factors have 2 terms: (x+4) and (y+4)
Lets get started :)
The Volume formula of a Cylinder is
V =

r²h
(r = radius, h = height)
The radius given is 8 and the height is 4, We can plug in the known values
V =

(8)²(4)
=

256
=
256
units³ (You can leave the answer in this form)
≈
804.2 units³ (approximately)
Units
³ because it is a volume (3D shape)
