If a rectangle has an area of 2x^2+7x+3 find the perimeter
Helen [10]

Answer:

Perimeter of the rectangle=6x+8 square units

Step-by-step explanation:

Given that area of rectangle is 2x^2+7x+3

Area of rectangle=lw square units

2x^2+7x+3=2x^2+x+6x+3

=x(2x+1)+3(2x+1)

=(x+3)(2x+1)

2x^2+7x+3=(x+3)(2x+1)

Comparing the above equation with the given area we get

lw=(x+3)(2x+1)

Therefore length=x+3 and width=2x+1

To find the perimeter :

Perimeter of the rectangle=2(l+w) square units

=2((x+3)+(2x+1))

=2(x+3+2x+1)

=2(3x+4)

=6x+8

Therefore perimeter of the rectangle=6x+8 square units

scoundrel [369]

Answer:  If the 40% off coupon is used, the subtotal will be $12.69

The gratuity would be exactly $4.23   (He will probably leave $4.25)

Step-by-step explanation: To find out the amount  of the discount

.40 × 21.15 = 8.46

To find the new subtotal, subtract  12.15 - 8.46 = 12.69

To figure the tip:  .20 × 21.15 = 4.23

Changing the percent to a decimal means divide the 20 by 100.
