Answer:
If you meant to simplify the expression,
-8b+4ab
if factor: 4b(a-2)
Step-by-step explanation:
To simplify an expression, combine the like terms.
8b+4ab-16b, 8b and -16b are like terms.
-8b+4ab, notice 4ab has an extra a before the b, so it is not a like term of -8b
To factor it out:
The expression -8b+4ab both includes b in it.
Thus,
b(-8+4a) -8 and 4 can be has GCF of 4
=4b(a-2).
A^2 = 16
a^2 = 4^2
a = 4
answer:<span> side length = 4 unit</span>
Answer:
40 students would choose rap. Hope this helps! BTW nice job scaring people off
It is 40 because the total in the graph is 50 so you have to multiply everything by 4
Answer:
-4
Step-by-step explanation:
-5x-12=2x
-3x-12=0
-3x=12
3x=-12
x=-4
19-(-2)=21
1+15=16
(-6)-(-17)=-11
5-14=-9
just remember when ur subtracting a number from a bigger number, it becomes negative
and two negatives equal a positive
