Step-by-step explanation:

I am going to label each picture based on it's color.

For the yellow net, it is a rectangular prism. You can tell because when you fold the pieces together, it forms a rectangular prism. Also, all the parts fo teh net are rectangles.

For the green net, it is a square pyramid. For a square pyramid the base is a square. In the picture, the base is a square.

For the purple net, it is a triangular prism. For a triangular prism, it has a ractangle as a base. The purple shows a rectanlge base and triangle sides.

For the blue net, it is a triangular pyramid. A triangular pyramid has a triangle base. The blue has a triangle base.

Solve the system of equations by substitution.

n200080 [17]

Answer:

x = -8

y = -6

Step-by-step explanation:

y = -2x - 22

y = x + 2

x + 2 = -2x - 22

x + 2x = -22 - 2

3x = -24

x = -24 : 3

x= -8

y = -8 + 2

y = -6

A real estate broker acting as a property manager leased a building for 10 years at an annual rent of 48,000. They will receive

Eddi Din [679]

Answer:

Question... is the commission given 10 times or 3?

If the commission is 10 then

5*(48,000 * .075) + 3*(48,000 * .05) +2*(48,000 * .035)

5*(3600) + 3*(2400) +2*(1680)

= 28560

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If the commission is 3 then (once for first five years, once for the next three,

and once for the last two

(48,000 * .075) + (48,000 * .05) +(48,000 * .035)

=7680

What is the equation of the axis of symmetry for the function shown below?

Gennadij [26K]

Answer:

x=2

Step-by-step explanation:

The axis of symmetry can be calculated using the following formula:

$Xv= \frac{-b}{2a}$

In order to use this formula, we need to have the function written in it's polynomial formula:

$f(x)=ax^{2} +bx+c$

In order to do so, we have to isolate Y from the excercise's formula.

$y=-2(x-2)^2-5$

Then we resolve the square of the binomial knowing that (a+b)^2=a^2+2.a.b+b^2

$(x-2)^2= x^2+2.x.(-2)+(-2)^2$

$(x-2)^2= x^2-4x+4$

Now we have that:

$y=-2.(x^2-4x+4)-5$

$y=-2x^2+8x-8-5$

$y=-2x^2+8x-13$

As we have now the polynomyal formula, we know that a=-2, b=8 and c=-13. We supplant on the formula and get:

$Xv= \frac{-b}{2a}$

$Xv= \frac{-8}{2.(-2)}$

$Xv= \frac{-8}{-4)}$

$Xv= 2$

Given the figure as marked, find the perimeter and area.

Kazeer [188]

Answer:

Step-by-step explanation:

Left triangle: it has two congruent legs because has an angle of 45 degrees

AB = $\sqrt{ 2 * 6^2} = 6\sqrt{2}$ cm

the triangle on the the right is half on an equilateral one

BC = 12 cm

CH = 6√3 cm

AC= (6 + 6√3) cm

2p = 6 + 6√3 + 12 + 6√2 = 18 + 6√3 + 6√2 = 6(3 + √3 + √2) cm

Area = [6(1+√3) * 6]/2 = 18(1+√3) cm^2
