Answer:

21 m²

Step-by-step explanation:

Area of a trapezoid is given by the formula:

A = (a+b)/2×h

(where h is the vertcial height, and a and b are the parallel lines)

Substituting values given gives us:

A = (5+9)/2×3

A = 14/2×3

A = 7×3

A = 21

Units will be m² as this is area.

Consider the expression: (x + 3)•(y + 1)•(x + 2)
emmainna [20.7K]

Answer:

Step-by-step explanation:

First we multiply x through (y+1). This equals xy +x.

Second we take 3 through (y+1). This equals 3y+3.

Next we take xy + x through (x+2). This equals 2x squared, y + 2x squared.

Fourth we take 3y+3 through (x+2). This equals 6xy + 6x.

stepladder [879]
X=Amount of games in each case.

He has 2 cases of videos games with the same number of games in each case:

2x+2x

He gives 4 away to his brother:

2x+2x-4

Now he has 10 games left:

2x+2x-4=10
4x-4+4=10+4
4x/4=14/4
X=3.5. round up to 4 because you can’t have .5 of a game.

Richordo had 4 video games in each case.
