Answer:
i think the answer are the 1st one the 4th one, & the 7th one.
Step-by-step explanation:
your equation is:
342/6=<em>x</em>
342 is the total amount of peanuts.
6 is the amount of bags.
<em>x</em> is the number of peanuts in each bag.
<em>x</em> = 57
This is pretty simple. Since there are 19.8 gallons and every gallon is 3.65$, you multiply 19.8 by 3.65 to get $72.27. It will cost 72.27$ to fill up the tank.
Answer:
2x + 1.
Step-by-step explanation:
y=x^2 + x + 1
Using the algebraic derivative rule, if y = ax^n then y' = anx^(n-1) :
The derivative is 2x^(2 - 1) + 1x^(1-1)
= 2x^1 + x^0
= 2x + 1.
B is maybe the answer not really sure
Answer:
set width as a, so length is 2a-4
a(2a-4)=70
2a^2 - 4a = 70
a^2 - 2a = 35
a^2 - 2a + 1 = 36
(a-1)^2 = 36 Because width can not be negative so we only take possitive answer.
(a-1) = 6
a = 7
2(7) - 4
=14-4
=10
Length = 10
Width = 7
