Answer: -x + 4y
Step-by-step explanation:
-3(2x-y) + 2y+2(x+y)
-6x + 3y + 2y + 2x + 2y
-6x + 2x +3y + 2y + 2y
-6x + 5x + 4y
-x + 4y
Answer:
![A=2x^2+3x-5](https://tex.z-dn.net/?f=A%3D2x%5E2%2B3x-5)
Step-by-step explanation:
Given that,
Length = (2x+5) cm
Width = (x-1) cm
We need to find the area of a rectangle. The formula for the area of rectangle is given by :
A = lb
![A=(2x+5)(x-1)\\\\=2x^2-2x+5x-5\\\\=2x^2+3x-5](https://tex.z-dn.net/?f=A%3D%282x%2B5%29%28x-1%29%5C%5C%5C%5C%3D2x%5E2-2x%2B5x-5%5C%5C%5C%5C%3D2x%5E2%2B3x-5)
So, the required area is equal to
.
Answer:
2 1/14
Step-by-step explanation:
First, we will equalize the denominators of the fractions.
(1/7) × 2 = 2/14
Then we can solve this equation.
2 2/14 - 1/14 = 2 1/14
