Hai !
6x+7+x^2+2x^2-3
6x+7+x^2+2x^2+-3
combine like terms
6x+7+x^2+2x^2+-3
(x^2+2x^2)+(6x)+(7+-3)
=3x^2+6x+4
Cheers :3
The answer is 120 degrees on edgenutiy<span />
3(5x+2)=8x+20
15x+6=8x+20
15x-8x=20-6
7x=14
then you divide both sides by 2
The answer is 2.
Let x = the length of a side of the square (m).
The area is
A = x²
The perimeter is
P = 4x
The rate of change of P with respect to x is
P'(x) = 4 (independent of x)
When A = 49 m², then x = 7 m.
The rate of P is 4.
Answer: 4
If you divide 27 by 75 you will get .36 calories. .36 is how many calories are in one gram of corn flakes. So if you multiply .36 and 120 you will get 43.2 therefore there is 43.2 calories in 120 grams of corn flakes.
