Answer: x= 10
Step-by-step explanation:
l= 40
w=20
P=l+w+l+w
120=5x-10+2x+5x-10+2x
120= 14x-20
120+20=14
140=14x
x=10
Answer:
ok
Step-by-step explanation:
x+7+25+2x+4=180
3x+11+25=180
3x=180-36
3x=144
<em>x</em><em>=</em><em>1</em><em>4</em><em>4</em><em>/</em><em>3</em>
<em>x</em><em>=</em><em>4</em><em>8</em>
Answer:
Combined volume of the two game systems
cubic inches
Step-by-step explanation:
Volume of a cuboid = length × breadth × height
Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.
So,
Volume of Soham's video game system = 8 × 6 × 2 =
cubic inches
As Sean's video game system measures 1 inch longer on all sides,
the video game system measures
inches long,
inches wide, and
inches tall.
Volume of the video game system = 10 × 8 × 4 =
cubic inches.
Therefore,
Combined volume of the two game systems =
cubic inches
