Answer:
Option B. 
Step-by-step explanation:
we have
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
First put it in standard form:
<span>x^2 −14x -15 =0
a =1 b =-14 c=-15
Then use the quadratic formula:
x = [-b +-sq root (b^2 - 4ac)] / 2a
x = [--14 +- sq root (14^2 -4*1*-15] / 2*1
x = [14 +-sq root (196 +60)] / 2
</span><span>x = [14 +- 16] / 2
x1 = 15
x2 = -1

Answer:
c
Step-by-step explanation:
im a math genius
A gallon of gasoline cost 30 cents in 1960 an
$1.30 in 1980
percent increase in the price = ?
first we have to convert cents into dollars so that both amounts have to be in same unit
30 cents = $0.3
increase in gasoline cost = $1.30 - 0.3 = $1
now for calculating percent increase divide this with the new amount and than multiply with 100
percent increase = ($1 / $1.30) x 100 = 76.92% = 77% approx.
so, there is 77% increase in the price of gasoline
