Answer:
3x-2
Step-by-step explanation:
-2x-2+5x=-2x+5x-2=3x-2
Answer:
18
Step-by-step explanation:
-3(2x-3)
-3x(-6)
-3x-6=18 because the negatives cancel each other out.
a. Parameterize
by

with
.
b/c. The line integral of
over
is




d. Notice that we can write the line integral as

By Green's theorem, the line integral is equivalent to

where
is the triangle bounded by
, and this integral is simply twice the area of
.
is a right triangle with legs 2 and 5, so its area is 5 and the integral's value is 10.
The answer is what is shown on the phone
Henrietta solved a rational equation by multiplying both sides by
.She did not find the least common multiple of the denominators .If she had find the least common denominator which is 3x(x+2) then the question can have been simplified in more simpler form.
Henrietta can have got rid of denominator and then use the distributive rule .
So the first option
A:She could use the least common multiple of the denominator is right
