Find the value of x. If necessary, round to the nearest tenth.

tankabanditka [31]

Answer:

B. 9.7 in.

Step-by-step explanation:

We have been given an image of a triangle. We are asked to find the value of x.

We will use area of triangle formula to solve our given problem.

$\text{Area of triangle}=\frac{1}{2}\times \text{Base*Height}$

$47\text{ in}^2=\frac{1}{2}\times x*x$

$2*47\text{ in}^2=\frac{1}{2}*2\times x^2$

$94\text{ in}^2=x^2$

Taking square root of both sides we will get,

$x=\sqrt{94\text{ in}^2}$

$x=9.6953597\text{ in}\approx 9.7\text{ in}$

Therefore, the value of x is 9.7 inches and option B is the correct choice.

12. $\frac{r-3}{-4-(-8)} = -5$
$\frac{r-3}{4} = -5$
r - 3 = 4(-5)
r - 3 = -20
r = -20 + 3
r = -17

13. $\frac{r-2}{-2-5} = \frac{5}{6}$
$\frac{r-2}{-7} = \frac{5}{6}$
6(r - 2) = -7(5)
6r - 12 = -35
6r = -35 + 12
6r = - 23
r = $\frac{-23}{6}$
