Answer:

204 ft^2

Step-by-step explanation:

triangle on the left:

A= l x w x 1/2

A = 12 x 5 x 1/2

A = 30 ft^2

triangle on the right:

Same thing

A = 30 ft^2

square in the middle:

A = l x w

A = 12 x 12

A = 144 ft^2

Add them up:

30 + 30 + 144 = 204 ft^2

Solve c: P = a+b+c+d / 4

m_a_m_a [10]

Answer:

as written: c = P - a - b - d/4
with parentheses: c = 4P - a - b - d

Step-by-step explanation:

The meaning of the given expression is ...

P = a + b + c + (d/4)

To solve for c, subtract all the terms on the right side not containing c.

P -(a + b + (d/4)) = c

c = P - a - b - (d/4)

_____

In such equations, parentheses are commonly missing. If that is the case here, then first we undo the division by 4, then we subtract the "not c" terms.

P = (a + b + c + d)/4 . . . . maybe what you meant

4P = a + b + c + d . . . . . . multiply by 4

4P - (a +b +d) = c

c = 4P -a -b -d

Un auto viaja con una velocidad promedio de 84 kilómetros por hora. ¿En cuánto tiempo viaja 462 kilómetros?

timama [110]

The car takes the time 5.5 hours i.e.5 hours and 30 minutes to travel 462 kilometres when the car travels at average speed of 84 kilometres per hour

Given the average speed of the car is 84 kilometres per hour and the distance to be travelled is 462 kilometres and asked to find the time taken for the journey of 462 kilometres

To calculate the time taken for the journey we use the below-mentioned formula

$speed=\frac{distance}{Time taken}$
