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:
128
Step-by-step explanation:
well x be 128 cause their vertical angles
Answer:
f(8)=20..The answer is 8 :)
10x^2 + 27x - 28
= (2x + 7)(5x - 4)
So 2x + 7 and 5x - 4 are factors
Answer
D. 2x + 7
