Step-by-step explanation:
First I do it as separate equations 2x-7=0 and 5x+3=0. In this equation you get two answers so you first answer 2x-7=0
2x-7=0
+7 +7
2x=7
/2 /2
x=7/2
Then do 5x+3=0
-3 -3
5x=-3
/5 /5
x= -3/5
Then you can check by putting them back in.
Use photo math for that 21
She will get 23 books.
So, first, you take the shipping away to get $93.05,
then you divide $93.05 by $3.95 which equals 23.55
and you can't have half a book; so it's 23!
Kelly can show 49 with 4 ten blocks and 9 one blocks, 49 ones blocks, and she take a one hundred grid block, places 4 tens on 4 columns of the 100 and 9 one blocks on one row of the 100 grid block.
Answer:
P(x) = 15x^2 + 2x + 4
Step-by-step explanation:
To simplify:
combine like terms
8x^2 + 7x^2 = 15x^2
There are no other like terms.
This equation cannot be simplified any further with the given information.
P(x) = 15x^2 + 2x + 4
