L=n-2, W=4+L=n+2

A=LW, since L=n-2 and W=n+2 we have:

A=(n-2)(n+2)  so it could be this expression or the expansion

A=n^2-4

What is the area of a parallelogram with a base of 0.56 cm and a height of 0.33 cm (to the nearest hundredths)? A) 0.18 cm2 B) 0
valentinak56 [21]

Answer: A) 0.18 cm²

Step-by-step explanation:

To calculate the area of a parallelogram you must apply the formula shown below:

A=b*h

Where b is the base and h is the height of the parallelogram.

You know the values of the base and the value of the height.

Therefore, when you susbstitute these values into the equation shown above, you obtain the following result:

A=0.56*0.33cm=0.18cm^{2}

Marian went shopping and bought clothes for $66.17 and books for $44.98. She then had a meal at the mall for $20.15. Which is th
scZoUnD [109]

Answer:

Either 130 or 131 would be acceptable.

Step-by-step explanation:

When we estimate, we do not use exact values.

66.17 is close to 66

44.98 is close to 45

20.15 is close to 20

           

Add the estimates together: 66+ 45+ 20 = 131

We could also estimate 66.17 to 65 which would give us an estimate of 130

Solve the linear equation. 8x+32=1/5(25x−15)−4x
Kipish [7]

Answer: x= 5

Step-by-step explanation:

8x+32=1/5(25x−15)−4x

8x + 32 = <u>25x -15</u> - 4x   <u><em>- 25x -15/  5</em></u>

                    5

8x + 32 = 5x -3 - 4x

8x + 4x - 5x = -32 - 3

7x =-35

x = 35/7

x= 5
