Answer:
The longest bar in her histogram is the Intervals 5-9 with the value of 5
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo
My answer:
- Intervals 0-4 : there are 2 results
- Intervals 5-9 : there are 5 results
- Intervals 10-14 : there are 4 results
- Intervals 15-19 : there are 5 results
So the longest bar in her histogram is the Intervals 5-9 with the value of 5
Hope it will find you well.
We can form two ratios to help us solve this:
(2x+6):10 = (x+6):8
(2x+6) (x+6)
--------- = --------
10 8
Cross multiply:
8(2x+6) = 10(x+6)
Foil:
16x + 48 = 10x + 60
Move like variables to the same side:
16x - 10x = 60 - 48
6x = 12
x = 2
Line AE = 2x+6
Plug 2 for x into the equation: 2(2) + 6 = 10
Hope this helps, and May the Force Be With You!

I'm terrible at math, so I'm sorry if I'm totally wrong, but I'm assuming you just take the average:
20+28=48m
48/2=24m
On average, it may take them 24m if they work together.

Step-by-step explanation:
y=6x²+12x+2
y=4x²+16x+16
6x²+12x+2=4x²+16x+16
6x²-4x²+12x-16x+2-16=0
2x²-4x-14=0
x²-2x-7=0
x²-2x+1-1-7=0
(x-1)²=8
x-1=±√8=±2√2
x=1±2√2
x≈1±2.83
x≈3.83,-1.83
x=2√2 -1≈1.828≈1.83
