(x+c)(x-d)
Step-by-step explanation:
if x²-ax-b=(x-c)(x+d)
from vieta theorem
c + d = -(-a)=a
cd = b
if x²+ax-b
from vieta theorem
c + d = -(a)=-a
cd = b
so the same c d but in opposite sign (x+c)(x-d)
3 gallons because 3/4 of a gallon covers 1/4 of a wall so you multiply the amount of gallons used for a wall times 4 which is 12/4 (keep the denominator the same ) and then divide 12 by 4 which is 3 gallons

About 2/3 of the animals at the shelter are dogs
Step-by-step explanation:
Let's first transform the mixed number to the corresponding improper fraction.
67 2/3 is equivalent to (3*67 + 2)/3 = 203/3
we are asked to find a fraction equivalent to 203/3%. To do this, we have to divide the fraction by 10, as follows:
203/3% = (203/3)*(1/100) = 203/300 ≈ 2/3
