Answer:
Step-by-step explanation:Answer:2695
8y^2 + 6y + 1
List the factors of a and c.
a: 1 x 8, 2 x 4
c: 1 x 1
Since c is positive find factors from the list that will add up to the absolute value of b.
1, 1, 2, and 4 -----> (1 x 2) + (1 x 4) = 6
Arrange these four factors accordingly. Because both b and c are positive, both parentheses will have a plus sign.
( + )( + )
Ask yourself, "Which two factors with y as a variable will multiply to give me 8y^2?" Fill in the parentheses.
(4y + )(2y + )
Use trial and error(by FOILing).
(4y + 1)(2y + 1)
Check answer.
(4y)(2y) = 8y^2
(4y)(1) = 4y
(2y)(1) = 2y
(1)(1) = 1
Set up as a polynomial.
8y^2 + 4y + 2y + 1
Combine like-terms.
8y^2 + 6y + 1
So 8y^2 + 6y + 1 is equal to (4y + 1)(2y + 1).
Answer:
80.04
Step-by-step explanation:
It is already arranged in ascending order,
N=30
P84=i((N+1)/100)=84(31/100)=26.04 th item
26.04th item=(26+(27-26(0.04))) th item
80+81-80(0.04)=80+0.04=80.04
Answer:
$850 equipment
$125 from donation
they need $725
Step-by-step explanation:
if they earn $4 per ticket,
725÷4= 181.25
