Answer 1
Answer:

Answer:

D.2y^2+11y-10.

Step-by-step explanation:

Given:

We need to reduce 7y+2y^2-7 by 3-4y

Solution:

To reduce the equation means we need to subtract the one equation from other.

First we will arrange the equation n proper format we get;

2y^2+7y-7  ⇒ equation 1

Also Arranging other equation we get;

-4y+3   ⇒ equation 2

Now we will subtract equation 2 from equation 1 we get;

(2y^2+7y-7)-(-4y+3)

Now Applying distributive property for the sign we get;

2y^2+7y-7+4y-3

Now Arranging the like terms we get;

2y2+7y-+4y-7-3\n\n2y^2+11y-10

Hence the reduce form of the given equation is 2y^2+11y-10.

A rectangle has vertices A(1, 3), B(1, 10), C(5, 10), and D(5, 3).

What is the perimeter of the rectangle?

Answers

The sides of the rectangle would be the width of 4 units and the length of 7 units
The equation of perimeter is P=2l+2w
If w=4 and l=7, the P=2(7)+2(4)
Therefore, P=14+8=22 units
