Mathematics

elena55 [62]3 years ago
8 0

Answer:

Step-by-step explanation:

There are 6 square faces to a cube, so each square has area 1350/6 = 225sqcm

The area of a square = length^2 where length is any side's length (they are all the same)

√225 = 15cm length

This makes the cube have volume 15^3 = 3375 cubic cm

Algebra!!!<br> 3 Questions Only take if you know ALL Answers<br> PLZZZ QUICK
vitfil [10]

Answer:

1. -7.5

2. $1

3. 40

Step-by-step explanation:

For number 1, it can be solved by using the PEMDAS method, or see explanation below:

6x - 4x - 36 = 6 - 2x

2x - 36= -2x + 6

4x + 36 = 6

4x = -30

x = -15/2 or -7.5

For number 2, substitute 3 into both equations:

f(x) =1.50(3) + 2.00

and

f(x) = 2.00(3) + 1.50

This would get $6.50 and $7.50, which, if subtracted, gets $1.

For number 3, do something similar to the previous problem. Substitute 3 for x. It would be 5(2^3), or 40.

Hope this helps!
