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: A. 62.7
Step-by-step explanation:
Using the Pythagorean Theorem, know the distance from the top of the tower to the spot on the ground 750 feet away is 1636 feet.
Now with all lengths of the triangle we can solve for the angle giving us 62.7169723304
Now we round to the tenth as instructed and get an answer of 62.7
Answer:
Salt Mixture B is defined by the equation $$, where $$is the number of teaspoons of salt and $$is the number of cups of water.
2. Which mixture tastes saltier? Explain how you know.
Step-by-step explanation:
The answer is 2million one hundred weird people.
The answer would be a.) The volume is the product of the area of the base 2x(2x+4) and the height 2x-2
Showed work if needed:
2x(2x-4) × 2x-2 = 4x-8x × 2x-2
= 4x-16x-2
= 4x+(-16x)-2
= -12x-2
=24
