Answer:x=4
Step-by-step explanation:
X2 = x2 + 2x + 9 Now subtract x2 from both sides and you have
x2- x2 = x2 - x2 + 2x + 9 or 0 = 2x + 9 now subtract 9 from both sides so you can solve for x.
0 -9 = 2x -9...and you have -9 = 2x
Now solve for x by dividing both sides by 2 and you arrive at x = -4.5

Answer:
The volume of cyclinder is 60 in³
Step-by-step explanation:
Using the formula of the volume of cyclinder, V = π×r²×h, where r is the radius and h is the height. Then you are able to find it by substituing the following value into the formula :
π = 3.14
r = 1.8 in
h = 5.9 in
V = 3.14×1.8²×5.9
= 60.0 in³ (3s.f)
