100 PTS!!!! The perimeter of a rectangle is 4(4x - 5) inches. the length of the sides of the rectangle are 2 x + 3 inches and 3x

vekshin1

Answer:

2 sides are $\frac{33}{13}$ or 2.5

2 sides are $\frac{47}{13}$ or 3.6

Step-by-step explanation:

There must be 2 2x+3s and 2 3x+2s

The perimeter is the sum of the sides (it has 4 sides)

2(2x+3) + 2(3x+2) = 4(4x-5)

distributive property

2*2x + 2*3

4x+6

other one

2*3x + 2*2

6x+4

perimeter

4*4x + 4*-5

16x-20

together...

(4x+6) + (6x+4) = 16x-20

add like terms

10x+10 = 16x-20

add 20 to both sides

10x+30 = 16x

subtract 10x from both sides

30 = 26x

divide by 26 on both sides

$\frac{30}{26} = x$

simplify

$\frac{15}{13}$

Substitute the x value

2 of the sides are 2x+3

$2(\frac{15}{13} ) + 3$

$\frac{30}{13} + \frac{3}{1}$

$\frac{33}{13}$

or 2.5

other sides

$3(\frac{15}{13} ) + 2$

$\frac{45}{13} + \frac{2}{1}$

$\frac{47}{13}$ or 3.6

That's all I can say for now! Hope this helps and a thank won't hurt! :)

What is the y-intercept of this line?

Brilliant_brown [7]

Answer:

$\huge\boxed{5}$

Step-by-step explanation:

This equation is in slope intercept form ( $y=mx+b$ ). This is called slope intercept form for a reason - $m$ is always the slope and $b$ is always the y-intercept.

We can see that the coefficient on the x-term is $-\frac{4}{3}$ and the constant being added to it is 5.

This means 5 is the y-intercept.

Hope this helped!
