The corner of a room where two walls meet the floor should be a right triangle. Jeff makes a mark along each wall. One mark is 12
inches from the corner. The other is 9 inches from the corner. How
can Jeff use the Pythagorean Theorem to see if the walls form a
right angle?
If the distance across the floor from one mark to the other is
says that
inch(es), then the
because 122 + 92 = 0%, a right triangle is formed.

Step-by-step explanation:

If the distance across the floor from one mark to the other is [15] inches then the [Pythagorean Theorem] says that because 12^2+9^2=[15]^2, a right triangle is formed.

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}
