If DM = 45, what is the value of r?
r +3
4r - 28

A 12
B 13
C. 14
D. 15

-7 i hope this right

Step-by-step explanation:

Find the Greatest Common Factor (GCF).

GCF = 44

2 Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

4(\frac{4r}{4}-\frac{28}{4})4(

4

4r

−

4

28

)

3 Simplify each term in parentheses.

4(r-7)4(r−7)

14

Step-by-step explanation:

Got it right in a test ‍

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

answer: the common difference is -0.10
