The area of a playground is 204 yards squared the width of a playground at 5 yards longer than its length whats the length and t
Ilya [14]
W= width= L+5
L= length
Area= 204

Area= LW
204 square yards= LW
substitute w=L+5 for w
204= (L)(L+5)
204= L^2 + 5L
subtract 204 from both sides
0= L^2 + 5L - 204
factor
0= (L+17)(L-12)

0= L+17
-17= L

0= L-12
12 yards= L


WIDTH
Since the area cannot be a negative number, we'll use L=12 to find the width.

w=L+5
w=12+5
w=17 yards


CHECK:
204=(12)(17)
204=204


ANSWER: The length is 12 yards and the width is 17 yards.

Hope this helps! :)

Solve 6x^2 - 42 = 0 for the exact values of x
GREYUIT [131]

Answer:

The values of x are

x=-\sqrt{7} , x=\sqrt{7}

Step-by-step explanation:

we have

6x^{2}-42=0

Solve for x

Adds 42 both sides

6x^{2}-42+42=0+42

6x^{2}=42

Divide by 6 both sides

6x^{2}/6=42/6

simplify

x^2=7

square root both sides

x=\pm\sqrt{7}

therefore

The values of x are

x=-\sqrt{7} , x=\sqrt{7}
