Use picture Question 4: Is this equation an identity? Explain or show how you know *
2 points
at +64 = (a + b) (a' - ab - ab+ b3)
No. When I expanded the expression on the right side, I got an expression different
from the one on the left side.
Yes. When I expanded the expression on the right side, I got the same expression as
the left side.

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
