I don’t know if the answer is rite but imma guess 5
Answer:
D
x=-4+2√2 or x=-4-2√2
Step-by-step explanation:
3(x+4)²-24
3(x+4)²=24
(x+4)²=24/3
(x+4)²=8
x+4=√8
x+4=±2√2
x=-4+2√2 or x=-4-2√2
The formula for the perimeter of a rectangle is:
A=2l+2w.
We know the area is 116, so we can plug that in for A. Now, we cant solve the equation yet because it still has two variables. Since we know the length is 5 feet greater than the width, we can rewrite l in terms of w. So here is what our new equation will look like:
116=2(w+5)+2w
Now lets solve:
116=2w+10+2w
106=4w
w=26.5 ft.
The width is 26.5 ft.
Answer:
approximately 21484
Step-by-step explanation:
Volume= 4/3 pi r^3
30001= 4/3 pi r^3
solve for r to get 41.34747142
Then, use surface area formula
SA= 4pi r^2
SA=4pi(41.34747142)^2
SA= 21483.6355
Answer:
9/6 or 3/2 or 1 1/2
Step-by-step explanation:
Do distributive property to get rid of the parenthesis
4x + 2x + 3 = 12
combine like terms
6x + 3 = 12
move the 3 over by subtraction
6x = 9
divide by 6
x = 9/6 or 3/2 or 1 1/2
