Answer:

\large\boxed{a=\dfrac{f+d}{c}-b=\dfrac{f+d-bc}{c}}

Step-by-step explanation:

c(a+b)-d=f\qquad\text{add}\ d\ \text{to both sides}\\\\c(a+b)=f+d\qquad\text{divide both sides by }\ c\neq0\\\\a+b=\dfrac{f+d}{c}\qquad\text{subtract}\ b\ \text{from both sides}\\\\a=\dfrac{f+d}{c}-b\\\\a=\dfrac{f+d}{c}-\dfrac{bc}{c}\\\\a=\dfrac{f+d-bc}{c}

Answer:

a = \frac{f+d}{c} - b

Step-by-step explanation:

Given

c(a + b) - d = f ( add d to both sides )

c(a + b) = f + d ( divide both sides by the multiplier c )

a + b = \frac{f+d}{c} ( subtract b from both sides )

a = \frac{f+d}{c} - b

Find the area of the figure below
satela [25.4K]

Answer:

The total area is 300 ft^2

Step-by-step explanation:

First find  the area of the rectangle

A = l*w = 24*10 = 240

Then find the area of the triangle on the top

A = 1/2 bh

The base is 24 and the height is 15-10 = 5

A = 1/2 (24)*5 = 60

Add them together

240+60 = 300

The total area is 300 ft^2
