You can use F.O.I.L. for this, which if you don't know stands for first outer inner last, so multiply the first in each parentheses, then the outer, then the inner, then the last. yours would be 3*5+3*√7+(-√7)*5+(-√7)*√7 => 15+3√7-5√7-7 => 8-2√7
Final answer:
8-2√7

The expressions 100×10 and the more complicated
(100 - 4a)(10 + a)
are calculating annual (expected) revenue. In 100×10 the 100 is the number of decks and the 10 is the price per deck. In (100 - 4a)(10 + a) the 100-4a is the number of decks and the 10+a is the price per deck. So a must be the amount the price increases.
Answer: amount of price increase, last choice
Answer:
a=16
Step-by-step explanation:
A quotient of integers that is not a real number is; 40/22 = 1.818181818.
According to the question;
- We are required to write a quotient of integers which is not real number.
In essence, by considering integers, 40 and 22; we have;
= 1.818181818 .
The result, 1.818181818 is therefore not a real number.
