Your answer is (D) 480 sq in

12 Multiplied by 14 is equal to 168
And you Multiply 168 times 2 which is equal to 336

Then you Multiply 12× 12 Which is equal to 144 and you add 144×336
And that will give you the answer of =480

Answer: D

Step-by-step explanation: To find the area of a triangle, you multiply the base and the height, then divide by 2, but because there are 4 triangles, you can multiply 12 and 14, and then multiply again by 2. For the square, 12 times 12 is 144, when you add 336 (the area of the triangles) and 144 (the area of the square), you get 480.

Let's see what to do buddy...

_________________________________

The sum of the angles of each n-sided figure is found in the following equation :

(n - 2) \times 180

The question's figure is 5-sindes figure

so the sum the angles equal :

(5 - 2) \times 180 = 3 \times 180 = 540 \\

So we have :

90 + 107 + 144 + 138 + x = 54 0 \\

479 + x = 540

Subtract the sides of the equation minus 479

x = 540 - 479

x = 61

And we're done.

Thanks for watching buddy good luck.

Y = -3x +10 3x +y = 5 substitution method
spayn [35]

Answer:

no solutions

Step-by-step explanation:

y = -3x +10

3x +y = 5

Substitute the first equation into the second equation

Let every instance of y in the second equation be replaced with -3x+10

3x+ (-3x+10) = 5

Combine like terms

10 =5

This is never true so there are no solutions

(These are parallel lines with the same slope but different y intercepts)

Answer:

It's the third option: (x^2 - 5)(x - 7).

Step-by-step explanation:

x^3 – 7x^2 – 5x + 35

= x^2(x - 7) - 5(x - 7)        The (x - 7) is common so we have:

(x^2 - 5)(x - 7).

What is the answer??
Lubov Fominskaja [6]

Answer:

<h2>(0, -2)</h2>

Step-by-step explanation:

A(x, y)

rotated 180°: A'(-x, -y)

translated n units:

left (x - n, y)

right (x + n, y)

up (x, y + n)

down (x, y - n)

We have R(-3, 2)

rotated 180°: (-(-3), -2) = (3, -2)

translated 3 units left: (3 - 3, -2) = (0, -2)
