Answer:

f = $\frac{-163}{27}$

Step-by-step explanation:

$\frac{3}{4} - \frac{-5-2}{f+5} = -6$

$\frac{3}{4} + 6 = \frac{-7}{f + 5}$

$\frac{27}{4} = \frac{-7}{f + 5} \\$

=> 27 * ( f + 5) = -7 * 4

=> 27f + 135 = -28

=> 27f = -163

=> f = $\frac{-163}{27}$

11. The rectangle has a width of 8 in, a length of x-5 in, and an area of 16 in). Solve for x.

Angelina_Jolie [31]

Use the area of rectangle formula which is:

$\displaystyle \large \tt{A = width \times length}$

Given that:

area of rectangle = 16
width = 8
length = x-5

Substitute in the formula:

$\displaystyle \large{16 = 8 \times (x - 5)} \\ \displaystyle \large{16 = 8(x - 5)}$

Distribute 8 in the expression:

$\displaystyle \large{16 = (8 \times x) + (8 \times ( - 5))} \\ \displaystyle \large{16 = 8x - 40}$

Move -40 to another side and change from -40 to 40.

$\displaystyle \large{16 + 40 = 8x} \\ \displaystyle \large{56= 8x} \\$

Then move 8 to divide 56, leaving only x.

$\displaystyle \large{ \frac{56}{8} = x} \\ \displaystyle \large{7 = x} \\$

Hence, the answer is:

$\displaystyle \large \boxed{x = 7} \\$

Does somebody knows this one?

Katarina [22]

Answer:

ok so first we need to find the area of the circle inside which is a=Pi*raduis^2

a=pi*1(radius is half of diamater)

a=3.14

ok then the area of the sqare including the circle is 16 so

16-3.14=12.86

this is is aprox since the area of pi is infinite and i just used 3.14

Hope This Helps!!!
