So the equation you would have to set up would be: (3m)+(2m-5)=90.
If your wondering where I got the 90 from I got it because the question states it is a right angle.
So now you combine like terms:
3m+2m=5m
Which leaves you:
5m+(-5)=90 or 5m-5=90
Then you do the opposite operation by changing subtraction to addition:
5m-5=90
+5
(Don’t forget your do the same on the other side)
5m-5=90
+5 +5
—————-
And then your left with:
5m=95
Then you divide by 5 on both sides by creating a fraction:
5m=95
—- —-
5 5
And you get your answer:
m=19

Answer:
x = -3/2
Step-by-step explanation:
4x² + 12x + 9 = 0
Use AC method to factor, or recognize the perfect square.
(2x + 3)² = 0
2x + 3 = 0
x = -3/2
Answer:
-4
Step-by-step explanation:
2 1/4 - 7 1/2 = -5.25
-5.25 - (-1 1/4) = -4
