Area: 5x + 10

Perimeter: 2x + 14

Step-by-step explanation:

Area = length times width

Perimeter = length (2) + width (2)

Area:

Multiply the length be the width. That gives you 5 (x + 2).

Then use the distributive property to simplify this expression. That gives you 5x + 10.

Perimeter:

Multiply the width by 2. That gives you 10.

Multiply the length by 2. That gives you 2x + 4

Add the 2 together. That gives you 10 + 2x + 4.

Combine all like terms. That gives you 2x + 14.

When Ben invests $4000.00 at 4%, he will have an additional $160 every year added to the 4000. Then the 4000 adds to the 4000 and the 4% is calculated.
Since Benn needs 4 and 1/2%, which is $180.00, this is the amount of money that is 4 and 1/2% of the 4000. 
So if he adds an additional $180 to the total amount of $4000 this will give him the 4 and 1/2% of his initial investment.
So we can determine that x is the amount he needs to invest.
If 0.04(4000)+0.055x=0.045(4000+x)
160+0.055x=180+0.045x
0.010x=20
x=$2000
