Answer:

Question one = 35a - 15

Question two = 9

Step-by-step explanation:

Distributive property means to multiply all the numbers inside the parenthesis

by the outside number. 5 x 7a equals 35a and 5 x 3 = 15.

35 x 9 - 315 - 15 = 300

A = 9

Simplify each expression using Product to a Power Property a. (9a)^2 b. ( 3x)^2

antiseptic1488 [7]

$\begin{gathered} a)81a^2 \\ b)9x^2 \end{gathered}$

1) Let's simplify those expressions making use of exponents rules:

$(9a)^2=81a^2$

Note that the exponent outside the parenthesis is 'distributed' over each term inside.

2) Similarly for the second expression we can state that:

$(3x)^2=9x^2$
