Answer:

Perimeter of Triangle: $6x+15$

$x=12.5$

Step-by-step explanation:

The perimeter is the sum of all of the sides of the triangle.

Hence, the perimeter $=3x+3x+15=6x+15$

Since the perimeter is 90, $6x+15=90$ .

Subtract 15 from both sides:

$6x+15-15=90-15$

$6x=75$

Divide both sides by 6:

$\frac{6x}{6}=\frac{75}{6}$

$x=12.5$

Plz help and show work plz

Answer:

3rd option

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (- 1, - 25 ) , then

f(x) = (x - (- 1) )² - 25 , that is

= (x + 1)² - 25 ← expand using FOIL

= x² + 2x + 1 - 25

= x² + 2x - 24

The measure of x in both parts is: 120°

Step-by-step explanation:

Part A:

We can clearly see that the figure in part a has six equal sides. So the given figure is a hexagon.

A hexagon has six equal sides in six equal interior angles.

Sum of interior angles of hexagon is 720°

So,

$Measure\ of\ one\ agnle=\frac{Sum\ of\ interior\ angles}{number\ of\ angles}\\=\frac{720}{6}\\=120$

Part B:

The figure is a Dodecagon with 12 sides.

The Dodecagon has 12 equal sides and angles.

The sum of internal angles of Dodecagon is 1440°

So,

$Measure\ of\ one\ angle=\frac{Sum\ of\ angles}{Number\ of\ angles}\\=\frac{1440}{12}\\=120$

The measure of x in both parts is: 120°

Nicki has 30 pencils. for every green pencil, she has 5 purple pencils. how many pencils of of each color could she have

Hatshy [7]

Answer:

Step-by-step explanation:

(1) P = 5G

(2) G + P = 30

Substituting (1) into (2) gives:

G + 5G = 30

6G = 30

G =5

So there are 5 green pencils.

Now using that in (1) gives us P = 5 x 5 = 25

So there are 5 green pencils and 25 purple pencils.
