Find the length of x
zaharov [31]

Answer:

The answer is 2

Step-by-step explanation:

The hypotenuses of the triangles are different. One is 4 and the other is 5.

Lets use ratios to find the relationship of the hypotenuse and the base.

2.5:5

Turn this into a fraction

2.5/5

Now divide

2.5/5 = 0.5

The base of the triangle is half the length of the hypotenuse.

So 4 is x’s hypotenuse so:

4 x 0.5 = 2

X = 2

Simplify the expression.
Tamiku [17]

Answer:

\boxed{=144--> C.}

Step-by-step explanation:

<u><em>You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract that came from left to right.</em></u>

First you calculate with parenthesis first.

(13-1)^2/2

12^2/2

Then you calculate with exponents.

12^2=12*12=144

144/2

Next, divide from left to right.

144/2=72

144/72=2

72*2=144

2*72=144

=72

2*72

Finally, multiply from left to right.

72*2=144

12*12=144

Final answer: \boxed{=144}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
