3a(4a – 5) - 4a (6 – 10a)

52a² - 39a

Step-by-step explanation:

Step 1: Write out expression

3a(4a - 5) - 4a(6 - 10a)

Step 2: Distribute

12a² - 15a - 24a + 40a²

Step 3: Combine like terms (a²)

52a² - 15a - 24a

Step 4: Combine like terms (a)

52a² - 39a

step-by-step explanation: examine the two-step equation.

which property of operations allows you to add the same constant term to both sides?

multiplication property of equality

division property of equality

addition property of equality

subtraction property of equality

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
