2 answers:
Answer:
Step-by-step explanation:
The FOIL method is used to multiply two binomials.
FOIL stand for:
First : Multiply the first term in each set of parenthesis.
Outer : Multiply the outer term in each set of parenthesis.
Inner : Multiply the inner term in each set of parenthesis.
Last: Multiply the last term in each set of parenthesis.
Given that:
Using the foil method:
[Using distributive property]
⇒
⇒
Combine like terms:
⇒
Therefore, the product of (2x – 7)(5x+5) using FOIL method is,

Answer:
a = 3, b = 12, c = 13
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)
(a^b)^c = a^(bc)

<em>Additional comment</em>
I find it easy to remember the rules of exponents by remembering that <em>an exponent signifies repeated multiplication</em>. It tells you how many times the base is a factor in the product.
Multiplication increases the number of times the base is a factor.
Similarly, division cancels factors from numerator and denominator, so decreases the number of times the base is a factor.
