x be the number of oranges

x + (x+2) = $4.20

2x + 2 = 4.20

2x = 2.20

x = 1.1

if you wanna check,

1.1 + (1.1 + 2) =$4.20

1.1 + 3.1 =$4.20

4.2 =$4.20

Alex = x = 1.1 oranges

Bobbie = (x+2) = 1.1 + 2 = 3.1 oranges

I'm not sure of the answer tho^^

Goryan [66]

Answer:

The volume of the triangular prism is $V=72\ cm^3$

Step-by-step explanation:

we know that

The volume of the triangular prism is equal to

$V=BL$

where

B is the area of the triangular face

L is the length of the prism

step 1

Find the area of the triangular face

The area of a triangle is equal to

$B=\frac{1}{2} bh$

we have

$b=3\ cm\\h=4\ cm$

substitute

$B=\frac{1}{2}(3)(4)=6\ cm^2$

step 2

Find the volume

we have

$B=6\ cm^2$

$L=12\ cm$

substitute in the formula of volume

$V=6(12)$

$V=72\ cm^3$
