Answer:
x^2 -9
Step-by-step explanation:
(x + 3)(x − 3)
FOIL
first x*x =x^2
outer -3x
inner 3x
last -3*-3 =-9
Add together
x^2 -3x+3x -9
Combine like terms
x^2 -9
Answer:
7 : 17.29
Step-by-step explanation:
==>Given:
Two similar cylinders:
Surface area of Cylinder A = 49cm²
Surface area of Cylinder B = 121cm²
==>Required:
Scale factor between both cylinders
==>Solution:
We can easily get the scale factor between both by taking the following steps:
=>Set up a ratio of their surface area:
Smaller cone surface area : larger cone surface area
49:121
= 49/121
=>Simplify the ratio gotten:
Dividing the denominator and the numerator by 7, would give us,
7/17.29
= 7:17.29
