Answer:
2x² - 5x - 3
Step-by-step explanation:
Given
(x - 3)(2x + 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(2x + 1) - 3(2x + 1) ← distribute parenthesis
= 2x² + x - 6x - 3 ← collect like terms
= 2x² - 5x - 3
2 surfaces are 6 in by 9 in, meaning that their combined area is 2(54 in^2).
2 surfaces are 6 in by 18 in; combined area is 2(108 in^2).
2 surfaces are 9 in by 18 in; combined area is 2(162 in^2).
Add up these areas: A = 2(54+108+162) in^2 = 648 in^2 (answer)
C. (15 + 10) x (4 + 3)
A equals 5 x 7 which is 35
B equals 5 x 1 which is 5
C equals 25 x 7 which is 175
D equals 25 x 1 which is 25

Answer:
5/8 * 2 * pi *r
Step-by-step explanation:
First find the circumference of the circle
C = 2 * pi *r
Then multiply it by the fraction of the circle ( arc length) you wish to find
5/8 * 2 * pi *r
