Part 2)
Step-by-step explanation:
Part 1) Simplify the given equation
we have
In the left side, remove the parenthesis and apply the distributive property
Remember that
so
Combine like terms left side
Adds 7x both sides
subtract 15 both sides
Divide by 7 both sides

Answer:
option A. 36 square inches
Step-by-step explanation:
The figure is a trapezium
Area of a trapezium=1/2 *(sum of parallel sides) *height
From the diagram, the parell sides are 6 inches and 12 inches ,and the height is 4 inches.
We substitute these values into the formula.
This implies that, the area
Thus the area is 36 square inches
(1) y = 7x , (2) y = 11x , (3) y = 9x , (4) y = 28x
given y varies directly as x then y = kx ( k is the constant of variation )
(1) find k using the given conditions k = =
= 7
equation is y = 7x
(2) k = = 11
equation is y = 11x
(3) k = = 9
equation is y = 9x
(4) k = = 28
equation is y = 28x
