Answer:

C. x = -61/5

Step-by-step explanation:

7(x+5)+4(x+5) = 6x-6

First let's multiply the parenthesis parts.

7x+35 + 4x+20 = 6x-6

Combine like terms - combine all the x terms and the number terms. 7x + 4x = 11x, 35+20 = 55

11x + 55 = 6x - 6

Subtract 6x from both sides

5x + 55 = -6

Subtract 55 from both sides

5x = -61

x = -61/5

Answer:

$t(400)=673$ .

It means that 673 of 9 inch tiles are required to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.

Step-by-step explanation:

Given:

The function relating number of 9 inch tiles required and area to cover is:

$t(A)=\frac{144}{9.25^2}A$

Now, plug in 400 for $A$ to evaluate $t(400)$ .

$t(400)=\frac{144}{9.25^2}\times 400=\frac{144\times 400}{85.5625}=\frac{57600}{85.5625}=673.19\approx6225$

Therefore, Don required 673 of 9 inch tiles to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.
