The equation has three factors and equals zero
One of the factors must be zero.
Either 3x = 0 which means x = 0
or x - 4 = 0 which means x = 4
or 3x + 5 = 0 which means 3x = -5 so x = -5/3
The answer is C
E cannot be correct in this question as you are asked to “solve” and not just pick a correct option

Answer:
2 1/4 days
Step-by-step explanation:
You could extend your table a bit to help answer this.
(days, hours)
(1, 24)
(1/2, 12)
(1/4, 6)
(2, 48)
Now, we observe that 54 hours is 6 more hours than 48 hours, so will be 1/4 day more than 2 days.
54 hours is 2 1/4 days
Answer:
y is 4
Step-by-step explanation:
so the equation is y = kx ( k is the constant)
We've been given x as 5 & y as 10 so we can use these values to find the constant .
10 = k(5)
k = 2
so now , we can find y
y = 2 × 2
y = 4
B>a
b=8a-1
and we are told that 98=a+b so a=98-b, using this value for a in the equation above gives you:
b=8(98-b)-1
b=784-8b-1
b=783-8b
9b=783
b=87, and since a+b=98, a=11
so a and b are 11 and 87
