Answer: x = 21°

Step-by-step explanation:

37 + 4x + (3x - 4) = 180° Original Equation

37 + 4x + 3x - 4 = 180° Commutative Property of Addition

7x + 33 = 180° Combine like terms

7x = 148° Subtract 33 from both sides

x = 21° Divide both sides by 7

Find the expression that represents the length of the hypotenuse of a right triangle whose legs measure m^2-n^2 and 2mn

My name is Ann [436]

$\bf c^2=a^2+b^2\qquad 
\begin{cases}
c=hypotenuse\\
a=adjacent\\
b=opposite\\
------\\
a=m^2-n^2\\
b=2mn
\end{cases}\\\\\\ c^2=(m^2-n^2)^2+(\underline{2mn})^2
\\\\\\
c^2=m^4-2m^2n^2+n^4+\underline{2^2m^2n^2}
\\\\\\
c^2=m^4-2m^2n^2+n^4+{4m^2n^2}
\\\\\\
c^2=m^4+2m^2n^2+n^4\impliedby \textit{perfect square trinomial}
\\\\\\
c^2=(m^2+n^2)^2\implies c=\sqrt{(m^2+n^2)^2}\implies c=m^2+n^2$

First you need to set up your equation.

If you read the question it states one equation IS THE SAME AMOUNT of another equation so here it is:

3x+7= 2x+18

You want to find out x in both equations so I’ll help step by step

1. Subtract 2x from both sides

This leaves you with x+7=18

2. Then subtract 7 on both sides

This leaves you with x=11

So x equals 11 for equations.

You can check by plugging in 11 in x. If you get 40 on both sides....

CONGRATS!! You did it

I hope this helped. Have a great day!
