Answer:
Step-by-step explanation:
we have the expression:
We need to multiply the two terms in the first parenthesis by the two terms in the second parenthesis:
we solve each term taking into account the law of signs
(-)(-)=+
and
(+)(-)=-
also for the first term we use that
thus we have:
it can be simplified a little more if we factor an r of the second and third term:
Answer:
5x+8
Step-by-step explanation:
First find the product of 5 and a number
5x
Then sum it with 8
5x+8
I think it is 53.54 because if you divide 40 by 3 and then multiply that by 4
The greatest common factor for 5 and 10 is 5
Answer:
<u><em>In the first hour they sold 350 tickets and in the second hour they sold 20% more so first we have to find 20% of 350, 20/100 x 350 = 70, so 20% of 350 is 70 now in the second they sold 350 + 70 = 420 tickets now you have to add it so 350 + 420 = 770, there is a price of $17.50 per ticket so 770 x 17.50 = 13475.</em></u>
