Answer:
a = - 10
Step-by-step explanation:
Given
= - 2
a is divided by 2. The inverse operation to division is multiplication, thus
Multiply both sides by 5 to clear the fraction
a = 5 × - 2 = - 10

<u>Given</u>:
Given that the graph of the linear equation.
We need to determine the equation of the graph.
<u>Slope</u>:
The slope of the equation can be determined using the formula,
Let us substitute the coordinates (2,0) and (0,-4) in the above formula, we get;
Thus, the slope of the equation is 2.
<u>y - intercept:</u>
The y - intercept of the equation is the value of y when x = 0.
Hence, from the graph, it is obvious that when x = 0, the value of y is -4.
Therefore, the value of the y - intercept is b = -4.
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,
Substituting the values, we have;
Subtracting both sides by 2x, we have;
Dividing both sides by -1, we get;
Thus, the equation of the line is
Hence, Option B is the correct answer.

Step-by-step explanation:
We know that the total surface area of a cuboid is the sum of the surface area of all six of its faces.
We also know that each opposing side has the same surface area. Thus the total surface area is equal to:
