The area of a triangle is A=1/2*b*h

So we have 72=1/2*10*h

72=5*h

14.4=h

So the height is 14.4 units

Hope this helped!

Pie

Answer:

Option B

Step-by-step explanation:

As here,

In all the options processes in 3rd step .

As the bases are same exponents get added. 

And in Option B 3rd step it has been correctly done form of,

${ ({2}^{ \frac{1}{4} } )}^{4} = 4$

Is correct simplification.

The function f(x) = 15(2)^x represents the growth of a frog population every year in a remote swamp. Elizabeth wants to manipula

weeeeeb [17]

Half one is 1/2;
half three is 3/2;
Thus, if f(x) represents annual growth, f(x)/2 shows it every half-year, like this:
$\dfrac{f(x)}{2} = \dfrac{15\cdot 2^x}{2} \\ \\ 
\dfrac{f(x)}{2} = \dfrac{15}{2}\cdot 2^x$

Written in plain text: f(x)=15/2*2^x

Please help, I have been trying for a while :( question on photo

Answer:

$\frac{x-22}{(x+2)(x-4)}$

Step-by-step explanation:

multiply the numerator/denominator of the first fraction by (x - 4)

multiply the numerator/denominator of the second fraction by (x + 2)

this ensures that the fractions have a common denominator

$\frac{4}{x+2}$ - $\frac{3}{x-4}$

= $\frac{4(x-4)}{(x+2)(x-4)}$ - $\frac{3(x+2)}{(x+2)(x-4)}$ ← subtract numerators leaving the common denominator

= $\frac{4x-16-3x-6}{(x+2)(x-4)}$

= $\frac{x-22}{(x+2)(x-4)}$
