Answer:
240 cm²
Step-by-step explanation:
We are required to determine the surface area of the figure;
To get the area we add the are of all the surfaces;
Area of triangle;
Area = 0.5 × b × h
There are two triangles;
Therefore;
Area of the two triangles;
Area = 0.5 × 6 × 8 × 2
= 48 cm²
Area of the rectangles;
Area of a rectangle = Length × width
Area of the first rectangle;
= 6 cm × 8 cm
= 48 cm²
Area of the second rectangle
= 8 cm × 8 cm
= 64 cm²
Area of the third rectangle
= 10 cm × 8 cm
= 80 cm²
The total surface area will be;
Area = 48 cm² + 48 cm² + 64 cm² + 80 cm²
= 240 cm²
Answer:
Step-by-step explanation:
Simplifying
6x + -3 = (3x + -2)
Reorder the terms:
-3 + 6x = (3x + -2)
Reorder the terms:
-3 + 6x = (-2 + 3x)
Remove parenthesis around (-2 + 3x)
-3 + 6x = -2 + 3x
Solving
-3 + 6x = -2 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-3 + 6x + -3x = -2 + 3x + -3x
Combine like terms: 6x + -3x = 3x
-3 + 3x = -2 + 3x + -3x
Combine like terms: 3x + -3x = 0
-3 + 3x = -2 + 0
-3 + 3x = -2
Add '3' to each side of the equation.
-3 + 3 + 3x = -2 + 3
Combine like terms: -3 + 3 = 0
0 + 3x = -2 + 3
3x = -2 + 3
Combine like terms: -2 + 3 = 1
3x = 1
Divide each side by '3'.
x = 0.3333333333
Simplifying
x = 0.3333333333
True, you can't simplify 1/2 any further
