Answer:
(x+1)^2 = 49
x = 6 x = -8
Step-by-step explanation:
x^2 + 2x – 48 = 0
Add 48 to each side
x^2 + 2x =48
Take the coefficient of x
2
Divide by 2
2/2=1
Square it
1^2 =1
x^2 + 2x +1=48+1
x^2 +2x+1 = 49
(x+1)^2 = 49
Take the square root of each side
sqrt((x+1)^2) =±sqrt( 49)
x+1 = ±7
Subtract 1 from each side
x+1-1 = -1 ±7
x = -1+7 x = -1 -7
x = 6 x = -8

Answer: 137.5 pounds
Step-by-step explanation:
Elijah has 2¹/₂ bags of candy. A single bag of candy weighs 55 pounds so to find the quantity of pounds that Elijah has, multiply 55 by the number of bags that Elijah has:
First convert bags to mixed fraction:
= 2¹/₂ = 5/2
Quantity that Elijah has:
= Number of bags * Weight per bag
= 5/2 * 55
= 137.5 pounds
