Find the area of the triangle with the vertices (2,1), (10,-1),
and(-1,8).

The area of triangle is 25 square units.

Step-by-step explanation:

Given information: Vertices of the triangle are (2,1), (10,-1), and (-1,8).

Formula for area of a triangle:

The given vertices are (2,1), (10,-1), and (-1,8).

Using the above formula the area of triangle is

On further simplification we get

Therefore the area of triangle is 25 square units.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
