-31 because if you do p.e.m.d .a .s
-2m = 16m - 9
First, take '16m' from both sides.
Second, add '-2m - 16m' to get '-18m'.
Third, divide both sides by '-18'.
Fourth, change the fraction into a negative.
Fifth, find the GCF of 9 and 18.
The GCF is 9.
Sixth, divide the numerator by the GCF.

÷
Seventh, divide the denominator by the GCF.

÷
Eighth, rewrite the fraction in simplest form.

Answer as fraction:

Answer as decimal:
Answer:
Domain= (-inf,inf)/(-∞,∞)
Range= (-inf,25/16]
x-intercepts= (0,0), (5/4,0)
y-intercepts=(0,0)
vertex= maximum (5/8,25/16)
The answer is 2 x10 = 20
To the power of b which is 15
The expression 4x^2represents 4.x.x
