To get the answer, you need to multiply the scale factor with the coordinate(In this case its P).So u need to multiply 6(x coordinate) X 3(Scale factor)= 18
and 2 X 3 = 6.....the Answer is D (18,6).....hope this helps.

Answer:

Area of triangle formula:

A = b*h/2

B is 18 and h is 13

B is base and h is height.

18 * 13 is 234.

We must divide by two because just multiplying the two numbers would result in an area of a square, divide by 2 for a triangle.

234/2 =

117 km²

Solve the equation for<br> x 3/4(x+21) = 10.5 <br> x =

MrRa [10]

<h3>✍️ Answer:</h3><h3> $x=-\frac{294}{13}$ </h3>

✽✽✽✽

$\frac{x\cdot \:3}{4\left(x+21\right)}=10.5$

$\mathrm{Multiply\:both\:sides\:by\:}4\left(x+21\right)$

$\frac{x\cdot \:3}{4\left(x+21\right)}\cdot \:4\left(x+21\right)=10.5\cdot \:4\left(x+21\right)$

$3x=42\left(x+21\right)$

$3x=42x+882$

$\mathrm{Subtract\:}42x\mathrm{\:from\:both\:sides}$

$3x-42x=42x+882-42x$

$-39x=882$

$\mathrm{Divide\:both\:sides\:by\:}-39$

$\frac{-39x}{-39}=\frac{882}{-39}$

$x=-\frac{294}{13}$

18x + 2x + 1=32<br> -1<br> 18x + 2x=31<br> And then what?

DerKrebs [107]

Let's look at the equation we have.
18x + 2x = 31

The first step would be to combine like terms. Ex: 18x and 2x
18x + 2x = 31
20x = 31

Now, to isolate the x, you would divide both sides by 20.
20x = 31
x = 1.55

x = 1.55

I hope this helps!
