Answer:
12m^2 - 9m -30
Step-by-step explanation:
So rewrite the equation to this:
4m * 3m
4m * -6
5 * 3m
5 * -6
Now solve:
4m * 3m = 12m^2
4m * -6 = -24m
5 * 3m = 15m
5 * -6 = -30
Now add them together in order:
12m^2 - 24m + 15m - 30
Simplify -24m and 15m:
12m^2 - 9m -30
Thus
12m^2 - 9m -30 is the answer
Hope this helps!
Answer:
q=0
Step-by-step explanation:
-2(q-5)=10
Divide each side by -2
-2/-2(q-5)=10/-2
q-5 = -5
Add 5 to each side
q-5+5 = -5+5
q=0
B. Just find the percentage to see if it is correct

It equals about .3356, but multiply it by 100 to get its percentage which is about 34%. So yes it is correct.
C.

Simplified would be a ratio of

So they would be incorrect

Answer: Degree = 3
Explanation:
The degree of any single variable monomial is simply the exponent itself.
For stuff like
, you'll need to add the exponents to determine the degree.
Number of yellow envelopes is 13-11 =2
Blue is 13
Green is 2*3 =6 so add the totals
2+6+13 which is 21
