Answer:
=7x^2−28
Step-by-step explanation:
Let's simplify step-by-step.
7(x−2)2+28(x−2)
Distribute:
=7x2+−28x+28+(28)(x)+(28)(−2)
=7x2+−28x+28+28x+−56
Combine Like Terms:
=7x2+−28x+28+28x+−56
=(7x2)+(−28x+28x)+(28+−56)
=7x2+−28
Answer:
change in saving account balance is -$149.98
Step-by-step explanation:
The computation of the change in saving account balance is as follows;

The answer is d.
Explanation:
To start with, classify the first two terms and factor out the common factor. i.e m is a common factor of m2-6m. By factoring it out we get m(m-6).
Follow the same procedure for terms three and four. ie
6 is a common factor of 6m-36. By factoring out, 6(m-6)
Regrouping
m(m-6)+6(m-6)
By factoring out (m-6), we get:
(m-6)(m+6)

Answer:
X = 92 degrees
Step-by-step explanation:
the angles of a triangle all add up to 180 degrees, so 40 plus 180-132 = 88
180-88= 92 so X = 92
