Answer:
area = 2x² - 17x - 21
Step-by-step explanation:
Area of the rectangle is:
area = (width*length)
area = (x+7)*(2x-3)
= x*2x + x*-3 + 7*2x + 7*-3
= 2x² - 3x - 14x - 21
= 2x² - 17x - 21
I know my math and your answer is going to be A.
Answer:
The integral is equal to
for an arbitrary constant C.
Step-by-step explanation:
a) If
then
so the integral becomes
. (the constant of integration is actually 5C, but this doesn't affect the result when taking derivatives, so we still denote it by C)
b) In this case
hence
. We rewrite the integral as
.
c) We use the trigonometric identity
is part b). The value of the integral is
. which coincides with part a)
Note that we just replaced 5+C by C. This is because we are asked for an indefinite integral. Each value of C defines a unique antiderivative, but we are not interested in specific values of C as this integral is the family of all antiderivatives. Part a) and b) don't coincide for specific values of C (they would if we were working with a definite integral), but they do represent the same family of functions.
Answer:3.42
Step-by-step explanation:to get the answer to a area equation you need to multiply the length by the width.
