Answer:
Width = 4 feet
Step-by-step explanation:
Let l = length
Let w = width
l = 3w
l - w = 8
3w - w = 8
2w = 8
w = 4
Answer:
X

Step-by-step explanation:
Answer: A: 30% B: Yes they are independent events because they can both happen without the other one. C: No they are not mutually exclusive events because both of them can happen at the same time
Step-by-step explanation:
45 / 100 = .45 = 45%
.45 x 2/3 = .3
.3= 30%
Answer:
first, subtract 17 on both sides: x²+2x-16=0
this cannot be factored, so use the quadratic formula to solve for x:
b²-4ac=2²-4(10(-16)=4+64=68
√68=2√17
so x=(-2+2√17)/2 or x=(-2-2√17)/2
x=-1+√17 or x=-1-√17
