Firstly, let's take first factor:
(y^3)^2 = y^(3*2) = y^6
and then:
y^6 * y^7 = y^(6 + 7) = y^13

△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

$29(1.75)=50.75\ units$

5 + 5x2 – 2x = 3x2 - 4<br> What is the answer to this question?

EastWind [94]

Answer:

Step-by-step explanation:

5 + 5 $x^{2}$ - 2x = 3 $x^{2}$ - 4

use your algebra skillz :P to move terms back and forth across the equal sign

5 $x^{2}$ - 3 $x^{2}$ - 2x + 5 +4 = 0

2 $x^{2}$ -2x +9 = 0

June starts out hiking due south and travels 4.50 km. When she comes to a canyon running east to west, she turns due east and tr

Yuki888 [10]

The Pythagorean theorem can be used to find the straight-line distance between the starting point and an ending point that is 4.5 km south and 12.0 km east of there.

d² = 4.5² + 12.0² = 20.25 + 144.0 = 164.25

d = √164.25 ≈ 12.816 . . . km
