It is a square trinomial:
4v^2 - 16v + 7 = 0
lets multiply and divide all by 4, the square term coefficient:
(16v^2 - 16(4)v + 28)(1/4) = 0
(4v - 14)(4v - 2)<span>(1/4) = 0
</span>factor 1/4
(4v - 14)(4v - 2)(1/2)<span>(1/2)</span> = 0
and divide each:
(2v - 7)(2v - 1) = 0
Answer:
Step-by-step explanation:
Two things to note;
1. Since there's only one 2 or hearts and one 3 of clubs
2. The first card is replaced after it's drawn
Probability of 2 of hearts = 1/52
Probability of 3 of clubs = 1/52
They both have the same probability of being drawn.

6x7=42
Answer:
L = 2 4/5 feet
Step-by-step explanation:
A = L x W
6 = L x 2 1/7
divide both sides by 2 1/7
6 divided by 2 1/7 = L (is the same as multiplying by the reciprocal)
6 x 7/15 = L
L = 14/5 or 2 4/5
