Answer
Step-by-step explanation:
The area would be length times width. x(4x+8) =96
4x^2+8x = 96
4x^2+8x-96=0. We need to factor.
It would be factored to (4x-16)(x+6) = 0
x would be -6 (x+6=0)
or x would be 4 (4x-16=0)
Why would the width be negative?!? So the answer is 4
Answer:
surface area is 46
Step-by-step explanation:
The midpoint of these two points would be (3.5, 0.5)
In order to find this, you need to take the average of the two point that you have. To do that, add the numbers together and divide by 2. Start with just the x values.
(5 + 2)/2 = 3.5
Now the y values
(-3 + 4)/2 = 0.5
This gives us the ordered pair of (3.5, 0.5)
Answer:
a=2
b=10.5
c=4
d=17.5
Step-by-step explanation:
so 3.5 miles per hour and the columns are miles and then hours
so an equation can be 3.5 (mi/hr) * t (time) = distance
so for a): 3.5*t=7
t=2
b) 3.5*3=distance
distance is 10.5
c) 3.5*t=14
t=4
d) 3.5*5=d
d= 17.5
