Answer:

x = -1

Step-by-step explanation:

8 = 2^(x + 4)

Rewriting 8 as 2^3

2^3 = 2^(x + 4)

Since the bases are the same, the exponents must be the same

3 = x+4

Subtract 4 from each side

3-4 =x+4-4

-1 =x

The area of a triangle is 225 in^2. If the width is 18 inches, find the height of the triangle

sergiy2304 [10]

$\textit{area of a triangle}=\cfrac{1}{2}\cdot b\cdot h\qquad 
\begin{cases}
b=\textit{base of triangle,}\\
\qquad \textit{may also be its width}\\
h=\textit{height of triangle}
\end{cases}
\\ \quad \\
b=width=18\qquad area=225
\\ \quad \\
225=\cfrac{1}{2}\cdot 18\cdot h\impliedby \textit{solve for "h"}$
