Answer:

48 cm^2

Step-by-step explanation:

First find the area of each shape.

2 triangles- [bxh]x1/2

(4 times 3)(divided by 2) = 6, but there are 2 triangles so 6+6=12

Square- (l x w)

3 times 3 (You get the other three from the other side of the rectangle) =9

Left rectangle- (l x w)

3 times 4 = 12

Right rectangle- (l x w)

5 times 3 (You get the three from the side of the square) = 15

Total: 2 triangles Area + Square Area  + Left rectangle Area+ Right rectangle Area = Surface Area

12 + 9 + 12 + 15 = 48 cm^2

Hope this helps!!

\large\texttt{Simplifying: }

4(4m -3) + -1m(m + -5) = -52

\large\texttt{Reorder the terms: }

4(-3 + 4m) + -1(m + -5) = -52

(-3 * 4 + 4m * 4) + -1(m + -5) = -52

(-12 + 16m) + -1(m + -5) = -52

\large\texttt{Reorder the terms: }

-12 + 16m + -1(-5 + m) = -52

-12 + 16m + (-5 * -1 + m * -1) = -52

-12 + 16m + (5 + -1m) = -52

\large\texttt{Reorder the terms: }

-12 + 5 + 16m + -1m = -52

\large\texttt{Combine like terms: }

-12 + 5 = -7

-7 + 16m + -1m = -52

\large\texttt{Combine like terms: }

16m + -1m = 15m

-7 + 15m = -52

\large\texttt{Solving: }

-7 + 15m = -52

-7 + 7 + 15m = -52 + 7

\large\texttt{Combine like terms: }

-7 + 7 = 0

0 + 15m = -52 + 7

15m = -52 + 7

\large\texttt{Combine like terms: }

-52 + 7 = -45

15m = -45

\large\texttt{Divide each side by '15'. }

15m ÷ 15 = -45 ÷ 15

m = -3

\large\texttt{Simplifying: }

m = -3

The space shuttle travels at about 28,000 km per hour. Using that information, estimate how many hours it will take the shuttle
dem82 [27]

Answer:

It depends on the location of the Earth and Saturn. Depending on whether the earth is between sun and saturn, or sun is between earth and saturn, the distance from earth to saturn varies. Obviously, if the earth is between the Sun and Saturn, the shortest distance will be. We will understand that the gap between Earth and Saturn is:    

Step-by-step explanation:

s = 1 275 000 000 km

The time required to travel that distance is:

t = s/v = 45535 hours or 1897.3 days
