Julie has 3 boxes of pens. The diagram shows the expression of the number in each box. Look at these equations. A=b+12 B=c+4 Write an equation to show the difference bewteen A and C

A = B + 12, while C = B - 4

Step-by-step explanation:

Given:

A = b + 12

B = c + 4

Equation to show the difference between A and c

If B = c + 4, then,

c = B - 4

A = B + 12, while C = B - 4

THEREFORE,

A - C can be expressed as ;

(b + 12) - (B - 4)

b + 12 - b + 4

b - b + 12 + 4

= 16

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
