Answer:

The answer is C.

Step-by-step explanation:

The L-shape can be divided into a rectangle of 20ft by 12-5=7ft and a square of 5ft by 5ft

So its area is the sum of the rectangle and the square

= 20*7 + 5*5

= 140 +25

= 165 ft^2

The answer is C.

Answer:

165 ft^2

Step-by-step explanation:

We need to break the figure into 2 parts

We have the square at the bottom right

The square is 5 by 5

A = 5*5 = 25

The rectangle is then 20 by (12-5) =7

The area of the rectangle is

A = 20 *7 = 140

Add the areas together

140+ 25

165 ft^2

The Lopez family left Dallas and went to Houston. Then they went from Houston to Austin. Then they took the shortest route back

ruslelena [56]

Answer:

I would assume they drove a car.

If so, then Dallas to Houston: 239.3 miles.

Then, Houston to Austin: 165.3 miles

Shortest route back to Texas: 913.5.

<u>I used g o o g l e m a p s to find my answer.</u>

Now add the numbers up:

239.3+165.3+913.5= 1318.1

They traveled 1318.1 miles in all.

What is the solution of the system of equations?

Elis [28]

Answer:

The answer to your question is:

x = 4

y = -1

z = -3

Step-by-step explanation:

3 x + 2 y + z = 7

5 x + 5 y + 4 z = 3

3 x + 2 y + 3 z = 1

$\left[\begin{array}{ccc}3&2&1\\5&5&4\\3&2&3\end{array}\right]$

= 45 + 10 + 24 - (30 + 24 + 15)

= 79 - 69

Δ = 10

$\left[\begin{array}{ccc}7&2&1\\3&5&4\\1&2&3\end{array}\right]$

= 105 + 6 + 8 - (18 + 56 + 5)

= 119 - 79

Δx = 40

$\left[\begin{array}{ccc}3&7&1\\5&3&4\\3&1&3\end{array}\right]$

= 27 + 5 + 84 - ( 105 + 12 + 9)

= 116 - 126

Δy = -10

$\left[\begin{array}{ccc}3&2&7\\5&5&3\\3&2&1\end{array}\right]$

= 15 + 70 + 18 - (10 + 18 + 105)

= 103 - 133

= -30

Δz = -30

x = Δx /Δ = 40/10 = 4

y = Δy/Δ = -10/10 = -1

z = Δz/Δ = -30/10 = -3
