Find a base length of a shipping box in the shape of a triangle prism.The shipping box has a volume of 276 cubic feet,a height o

Gala2k [10]

The base length will be found as follows:
volume of the triangular prism is given by:
V=1/2ab×h
where:
10 ft
b=6.9 ft
thus the height will be found as follows:
276=1/2×10×6.9×h
solving for h we get:
h=276/34.5
h=8 ft

Suppose A and B represent two different schools populations where A>B abd A and B must be greater than 0. Which of the follow

igor_vitrenko [27]

Hmm, one way we can do this is by assigning numbers to each

A=4 and B=3
A>B because 4>3

so

A. 2(A+B)=2(4+3)=2(7)=14
B. A+B^2=4+3^2=4+9=13
C. A^2+B^2=4^2+3^2=16+9=25
D. A^2-B^2=4^2-3^2=16-9=7

the largest is 25 so C
