It would be twelve
I hope that helps
Answer:
The GCF of 12 and 28 is 4.
Step-by-step explanation:
hope this helps
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 28 are: 1, 2, 4, 7, 14, 28
A. The figure given in A is a square pyramid and the
formula for the surface area of this figure is:
A = l w + l sqrt [(w/2)^2 + h^2] + w sqrt [(l/2)^2 + h^2]
where l and w are the lengths of the base and h is the
height of the pyramid. Since the base is square, so:
l = w = 16 in
h = 15 in
Substituting:
A = 16 * 16 + 16 sqrt [(16/2)^2 +15^2] + 16 sqrt [(16/2)^2
+ 15^2]
A = 256 + 272 + 272
A = 800 in^2
B. We are given a cone, the formula for surface area is:
A = πr (r + h^2 + r^2)
where h is the height = 8 in and r is the radius = 3 in
Substituting:
A = π * 3 (3 + sqrt (8^2 + 3^2))
A = 34.63π in^2 = 108.80 in^2
Answer:
x=-2 OR x=-4
Step-by-step explanation:
Step 1: Subtract -6x from both sides.
x2+8−−6x=−6x−−6x
x2+6x+8=0
Step 2: Factor left side of equation.
(x+2)(x+4)=0
Step 3: Set factors equal to 0.
x+2=0 or x+4=0
x=−2 or x=−4
Good luck! Hope this helps!
