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:B
Step-by-step explanation: 113,000 - 71,500 = 41,500
Answer:
Boris will have $250 in 10 months.

SYSTEM OF EQUATIONS
S+B = 17000
0.1S+0.07B=1280
Multiply the first equation by 0.1 and subtract the second equation
0.03B=420
B=14,000
S=3,000
The answer would be 10 because 9+-5=4+-1=5+5=10
