Express the area of this triangle as monomial.

gladu [14]

The formula of an area of a triangle:

$A=\dfrac{1}{2}bh$

b - base

h - height

We have b = 8x and h = 7x. Substitute:

$A=\dfrac{1}{2}(8x)(7x)=(4x)(7x)=28x^2$

<h3>Answer: 28x²</h3>

Answer:

$m = -\frac{194}{3}$

Step-by-step explanation:

I'm assuming you are trying to find m. In order to do so, you need to get m on one side.

Before doing that let's multiple -2 and -3m by $\frac{4}{3}$

$256=-\frac{8}{3} - 4m$

add $-\frac{8}{3}$ to both sides

$258\frac{2}{3}=-4m$

I would get rid of the fraction so I'd multiply both sides by $\frac{3}{1}$

$\frac{776}{3}*3 = 4m*3$

$776=-12m$

divide both sides by -12m

$m = -\frac{776}{12}$

which can be simplified to

$m = -\frac{194}{3}$

ALL UNLESS THAT $\frac{4}{3}$ IS A POWER
