Answer: x > 5
Step-by-step explanation: You need to isolate x. First, distribute the 1/2 into the parentheses. You will get:
4x + x + 2 > 12
Combine like terms.
5x + 2 > 12
Subtract 2 from each side.
5x > 10
Divide by 5 on each side.
X > 2
Since x is by itself, that is the answer.
x/4 = 3/2
x/2 = 3 (multiply both sides by 2)
x = 6 (multiply both sides by 2)
Therefore 6/4 = 3/2
1 cm equals to 10 mm, therefore 7000 mm = 700 cm.
Option B:
Surface area of the solid is 730 square millimeters.
Solution:
Area of the rectangle = length × breadth
Length of the top net = (25 + 8 + 8) mm = 41 mm
Breadth of the top net = 5 mm
Area of the Top net = 41 mm × 5 mm
= 205 square mm
Area of the second net = 25 mm × 8 mm
= 200 square mm
Area of the third net = 25 mm × 5 mm
= 125 square mm
Area of the bottom net = 25 mm × 8 mm
= 200 square mm
Surface area of the solid = 205 mm + 200 mm + 125 mm + 200 mm
= 730 square mm
Hence surface area of the solid is 730 square millimeters.
Option A is the correct answer.
