X(x+3)-7(x+3)
x2+3x-7x-21
x^2-4x-21
For number 9 just take the two functions and multiply or add them I can’t tell what sign that is
ANSWER
EXPLANATION
The expressions are
and
The greatest common factor is the product the least powers of the common factors.
The perimeter , width and length are all one dimensional so the preimeter of the resulting rectangle will be 2.5 * 36 = 90.
The area is 2 dimensional whereas the vase and height are one dimensional so the area will be increased by a factor of 5^2 ( or 25)
New rea = 36*25 = 900
solids are 3 dimensional so the ratio of thereir volumes is 5^3 : 3^3
= 125:27
to answer the last 2 use the formula Volume = pi r^2 h where r = radius and h = height of a cylinder
