We simply need to plug in x = 4 into x² + 2x
So plugging in x = 4, we get:
4² + 2(4)
Simplifying it, we get:
16 + 2(4)
16 + 8
24
When x = 4, x² + 2x will equal 24.
Answer:
V = 6079.04 ft³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius and h the height )
Here diameter = 22 , then r = 22 ÷ 2 = 11 and h = 16 , then
V = 3.14 × 11² × 16
= 3.14 × 121 × 16
≈ 6079.04 ft³ ( to the nearest hundredth )
Answer:
3/4
Step-by-step explanation:
1+3x=-x+4
1+3x-(-x)=4
1+3x+x=4
1+4x=4
4x=4-1
4x=3
x=3/4
