Step-by-step explanation:

If you have an equation for example:
4x + 6 = 3x - 4
You can see 4x and 3x are similar. So you want to basically combine them.
You subtract 3x from both sides to get 4x - 3x = 1x
4x - 3x = 1x or just x
You now have x + 6 = -4
Subtract 6 from both sides to get x = -10

Answer:

Solve like an equation, you gotta subtract both sides since u are adding so 10-v=10 v+10 v=10

△HFM ~ △PST

MissTica

Answer:

The perimeter of △HFM is 50.75 units

Step-by-step explanation:

The picture of the question in the attached figure

In this problem

Triangles HFM and PST are similar

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

step 1

Find the scale factor

Let

z ----> the scale factor

$z=\frac{HF}{PS}$

substitute the given values

$z=\frac{14}{8}=1.75$

step 2

Find the perimeter of triangle PST

$P=8+9+12=29\ units$

step 3

Find the perimeter of triangle HFM

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

The perimeter of triangle HFM is equal to the perimeter of triangle PST multiplied by the scale factor

$29(1.75)=50.75\ units$

Which expression is equivalent to 15+8x+3+2x

marishachu [46]

Answer:

10x + 18

Step-by-step explanation:

First, we need to add like terms. Like terms are terms that are alike. For instance 8x and 2x are like terms. 15 and 3 are also like terms.

So, we have to add 8x plus 2x and 15 plus 3. That’s comes out to 10x plus 18.

Therefore, this expression is equivalent to 10x + 18.
