What is the width of Averi's area model? (See picture)

Mathematics
1 answer:
shepuryov [24]3 years ago
8 0

Answer:

Width = x² + 5x - 4

Step-by-step explanation:

By the definition of an area model,

Area = Width × greatest common factor

Since, Area = 4x² + 20x - 16

And greatest common factor = 4

4x² + 20x - 16 = 4(Width)

By dividing both the sides of the equation by 4,

\frac{4x^2+20x-16}{4}=\frac{4(\text{Width})}{4}

x² + 5x - 4 = Width

Therefore, width = (x² + 5x - 4) will be he answer.

Solve the equation square root of x plus three plus four equals five for the variable. Show each step of your solution process
alekssr [168]

Answer:

x=-2

Step-by-step explanation:

The given expression is

\sqrt{x+3}+4=5

We group the constant terms on the right hand side to obtain;

\sqrt{x+3}=5-4

\Rightarrow \sqrt{x+3}=1

We square both sides of the equation to remove the square root.

\Rightarrow (\sqrt{x+3})^2=1^2

x+3=1

This will simplify to;

x=1-3

x=-2

Solve the system of equations. <br> 3x-4y=8 <br> 18x-5y=10
ipn [44]

Answer:

y = -2    x = 0

Step-by-step explanation:

1. 3x-4y = 8

2. 18-5y = 10

Multiply equation 1 by 6

3. 18x-24y = 48

Subtract equation 2 from equation 3

4. -19y = 38

        y = 38/-19

        y = -2

Sub y = -2 back into equation 1

      3x-4(-2) = 8

      3x + 8 = 8

      3x = 0

      x = 0/3

      x = 0
