To factor an expression, first you have to find the GCF or Greatest Common Factor of all of the pieces of the expression.

The GCF of 2y^2 and -4y is 2y

So, to factor this expression, we need to divide all of the pieces of the expression by the GCF.

2y(y-2)

2y^2 - 4y in completely factored form is 2y(y-2)

5. The 7th grade has 386 students. There are 32 more girls than boys in the grade.

timama [110]

Answer:

161 boys

Step-by-step explanation:

First you find the even amount of boys and girls out of 386

386 divided by 2 = 193

Then you subtract 32 boys and add the 32 to girls since there are 32 more girls than boys

(boys) 193 - 32 = 161

(girls) 193 + 32 = 225

So there are 161 boys and 225 girls

A rectangle has a width that is 50% of its length. The length of the rectangle is 12 inches. What is the area of the rectangle.

Stells [14]

Answer:

72 inches²

Step-by-step explanation:

Let $w$ be equal to the width of the rectangle.

Let $l$ be equal to the length of the rectangle.

$\frac{1}{2}l=w$

Plug in 12 inches as the length

$\frac{1}{2}(12)=w\\6=w$

Therefore, the width of the rectangle is 6 inches.

$A=lw$

Plug in 12 inches as the length and 6 inches as the width.

$A=(12)(6)\\A=72$

Therefore, the area of the rectangle is 72 inches².

I hope this helps!
