Answer:

K= -5

Steps:

Put together like terms

-5k + 2k = 40 - 25

-3k = 40 - 25

-3k = -15

Divide both sides by -3

Then you get your answer.

Answer:

$k = -5$

Step-by-step explanation:

Step 1: Add 5k to both sides

-5k + 25 + 5k = 40 - 2k + 5k

25 = 40 + 3k

Step 2: Subtract 40 from both sides

25 - 40 = 40 + 3k - 40

-15 = 3k

Step 3: Divide both sides by 3

-15 / 3 = 3k / 3

-5 = k

Answer: $k = -5$

In ABC, the measure of sides c is 3.9 cm If DEF is a dilation ABC with a scale factor of 2.5 what is the measure of side f

White raven [17]

Answer:

$F = 9.75cm$

Step-by-step explanation:

Given

In ABC;

$C = 3.9cm$

$Dilation = 2.5$

Required

Determine side F

In the given question;

DEF is a dilation of ABC

Comparing both triangles side by side,

Side F is a direct dilation of side C and this is calculated as follows

$F = Dilation * C$

$F = 2.5 * 3.9cm$

$F = 9.75cm$

The hypotenuse of a right triangle measures 6cm and one of its legs measures 3cm.Find the measure of the other leg. If necessary

belka [17]

Answer:

5.2

Step-by-step explanation:

a^2+b^2=c^2

Where c is the length of hypotenuse

and a, b are lengths of the legs.

Put in 6 for c,

Put in 3 for a and you get 9+b^2=36

Subtract 9 from both sides and get b^2= 27

Then find the square root of both sides to get b, so the answer is the square root of 27.

The cloest square root is 5, then apporixmate the tenths value and see if they work.

Answer: 5.2
