X^3+8
= x^3+2^3
<span>a^3 + b^3 = (a + b)(a^2 – ab + b^2)</span>
so
x^3+8
= x^3+2^3
= (x+2)(x^2-2x+2^2)
= (x+2)(x^2-2x+4)
Scale factor is used as multiplier or divider
If one size is 1.266, the next large size will be 1.125 larger than 1.266
1.266×1.125=1.424
I think I know this one.
Answer: V = 600 unit 2
Step-by-step explanation:
We have that
the volume of the rectangular pyramid is
V = (1/3) BH
where
B is the area of the rectangular face
H is the height of the pyramid
step 1
Find out B
B = (15)(10) unit 2
step 2
Find the volume
B = 150 unit 2
H = 12 unit
substitute
V = (1/3)(150)(12)
V = 600 unit 2
I hope this help you! :)
