Good evening ,
Answer:
x = StartFraction negative 8 Over 3 EndFraction, –2
Step-by-step explanation:
3x² + 14x + 16 = 0
3x² + 6x + 8x + 16 = 0
(3x² + 6x) + (8x + 16) = 0
3x(x+2) + 8(x+2) = 0
(x+2)(3x+8) = 0
x = -2 , x = -8/3.

I think it's 2+4×5=6 or 7+910=10
Because the fence's dimensions is 30 feet by 10 feet, you can assume that one side of the pool is 30 feet while the other, non-congruent side, is 10 feet. The formula for perimeter, which you are trying to find, is 2L+2W=P. In this problem, 30 will be your L and 10 will be your W. Therefore, 2(30) +2(10)=80.
So 80 feet will be your answer.
Answer:
Volume= Base x Height or Length x Width x Height
Step-by-step explanation:
Distribute: 3x+6+4=5x+7
Simplify: 3x+10=5x+7
Subtract 3x from both sides: 10=2x + 7
Subtract 7 from both sides: 3=2x
Divide by 2: x=3/2
x=3/2
