Answer:

p= -3

Step-by-step explanation:

3p - 6 = 3(2p + 5)

3p-6=6p+15

Add 6 to each side

3p=6p+21

subtract 6p from each side

-3p=21

dived each side by -3

p=-7

What is the length of the altitude of the equilateral triangle below
AVprozaik [17]

Answer

Find out the altitude of the equilateral triangle .

To proof

By using the trignometric identity.

tan\theta = \frac{Perpendicular}{base}

As shown in the diagram

and putting the values of the angles , base and perpendicular

tan 60^{\circ} = \frac{a}{4\sqrt{3}}

tan 60^{\circ} = \sqrt{3}

solving

\sqrt{3} = \frac{a}{4\sqrt{3}}

a = \sqrt{3}\times 4 \sqrt{3}

As

\sqrt{3}\times \sqrt{3} = 3

put in the above

a = 4 × 3

a = 12 units

The  length of the altitude of the equilateral triangle is 12 units .

Option (F) is correct .

Hence proved

What type of association would you expect between a persons age and hair length
hjlf

Answer:

The length of their hair reduces. This is because the length of hair is dependent on the growth phase (anagen phase) of the hair follicles. When one is young, the cells of the papilla divide more rapidly and hence cause the length of the hair to be long before reaching transitional phase (catagen phase) and then shed off in the telogen phase. The older one gets, the papilla cells do not divide as rapidly and the length of the hair shortens with age.

Find the slope of (2,3) and (6,7)
Brut [27]
To find the slope, we must use the formula stated below.

Slope = Change in Y / Change in X = (Y1 - Y2) / (X1 - X2)

Since our coordinates are given as (X, Y), we must pick a coordinate to be #1, and the other coordinate will be #2.

I'll use the first coordinate as our #1.

(3 - 6) / (2 - 7) = (-3) / (-5) = 3/5 which is our answer

The area of a rectangle is expressed as (14x + 28) square feet. If the width of the rectangle is 7 feet, write an expression to
DochEvi [55]

Answer:

The expression for the length of the rectangle is 2x + 4

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = length × width

The area of a rectangle is expressed as (14x + 28) square feet. If the width of the rectangle is 7 feet, then the expression for the length of the rectangle would be

Length = Area/ width

= (14x + 28)/7

The numerator has a common factor of 7. Therefore, if we factorize 7 out, it becomes

7(2x + 4)/7

Length = 2x + 4
