Solve for x math question

Colt1911 [192]

Square both sides

9(x + 2) = x + 4

Expand

9x + 18 = x + 4

Subtract x from both sides

9x + 18 - x = 4

Simplify 9x + 18 - x to 8x + 18

8x + 18 = 4

Subtract 18 from both sides

8x = 4 - 18

Simplify 4 - 18 to -14

8x = -14

Divide both sides by 8

x = -14/8

Simplify 14/8 to 7/4

<u>C. x = -7/4</u>

: Mark wants to fence 4 rectangular gardens, each with a length of feet 9/1/4 and a width of feet 4/1/2 . What is the total leng

Anastaziya [24]

Answer:

Mark needs 110 ft. fencing to surround all 4 gardens.

Step-by-step explanation:

Mark wants to fence 4 rectangular gardens. So we calculate the perimeter of the each garden by this formula

P = 2(L) + 2(W)

Total Length of the garden = $9\frac{1}{4} + 9\frac{1}{4}$

= $\frac{37}{4}+ \frac{37}{4}$

Length = 18.5 feet

Total width of the garden = $4\frac{1}{2} + 4\frac{1}{2}$

= $\frac{9}{2}+ \frac{9}{2}$

Width = 9.0 feet

Perimeter of the garden = 18.5 + 9 = 27.5 feet

Mark wants to fence 4 garden

Therefore, 27.5 × 4 = 110 feet.

Mark needs 110 ft. fencing to surround all 4 gardens.
