Answer:
2a(a+2b) square metres
Step-by-step explanation:
surface area of a box = 2(lw+wh+lh)
l is the length = a metres
w is the width = a mtres
h is the height = b metres
Substitute into the formula
surface area of a box = 2(a*a+ab+ab)
surface area of a box = 2(a² + 2ab)
surface area of a box = 2a(a+2b) square metres
This give sthe surface area of the box
The answers are the first, third, and last. I took the test.
Answer:
Lower quartile: 72
Upper quartile: 84
Step-by-step explanation:
Follow the instructions in the hint to solve the problem.
First, divide the data set into halves:
70, 70, 72, 75, 79
80, 80, 84, 89, 95
Now, find the median of the two sets. The median of set #1 is 72, as that is the number in the middle of the data.
The median of set #2 is 84 for the same reason.
Upper and lower quartiles are just different words for upper and lower medians. The upper quartile is the higher number, and the lower quartile is the lower number.

I’m glad that you love math keep it up though why don’t you answer the your questions but anyway I’m not here to judge just to answer
Now the answer is =-4 =-1 = 3 = 5 = 6
