Write an expression to represent the area of a rectangle if the length of a rectangle is three units more than its width

1 answer:

5 0

We can call the width “x”. Since the length is three units more than its width, we can call the length “x+3”.

Thus, the area is x(x+3), which simplifies to x^2+3x.

13. Find 3 fractions that are equivalent to 2/3. Explain how you found your answers

Rashid [163]

Answer:

$\frac{4}{6} =\frac{6}{9}= \frac{8}{12}$

Step-by-step explanation:

<em>I'm assuming this is asking for 3 separate fractions that are each equal to 2/3</em>

Remember, multiplying the top and bottom of a fraction by a number will not change the fraction.

$\frac{2}{3} *\frac{2}{2} =\frac{4}{6}$

$\frac{2}{3} *\frac{3}{3} =\frac{6}{9}$

$\frac{2}{3} *\frac{4}{4} =\frac{8}{12}$

These three fractions are all equal to 2/3

The difference of two numbers is 1. their sum is 19. find the numbers.

Umnica [9.8K]

Answer:

x = 10

y = 9

Step-by-step explanation:

First, you need to write two equations that represent the information given. I'm going to set the two numbers and x and y.

x - y = 1

x + y = 19

This turns it into a systems of equations. When you add the two equations, keeping everything on each side, you eliminate a variable, and solve for the other.

2x = 20

x = 10

Now, you'd plug x into either original equation.

(10) - y = 1

-y = -9

x = 10

I hope this helped!
