Answer:

Step-by-step explanation:

3 ( y + 8) = 2y - 6

3y + 24 = 2y - 6

3y - 2y = - 6 - 24

y = - 30

(x^2–x–4)multiplied by(x–5)

Sergio [31]

$(x-5)(x^2-x-4) =x^3-6x^2+x+20$

Step-by-step explanation:

Given polynomials are:

$x^2-x-4\\and\\x-5$

Both polynomials have to be multiplied. We will use distributive property for the said purpose

So,

$(x-5)(x^2-x-4)\\=x(x^2-x-4)-5(x^2-x-4)\\=x^3-x^2-4x-5x^2+5x+20$

Combining alike terms

$=x^3-x^2-5x^2-4x+5x+20\\=x^3-6x^2+x+20$

Hence,

$(x-5)(x^2-x-4) =x^3-6x^2+x+20$

Find the volume of a regular triangular pyramid if it has height h=12 cm, base edge b=10 cm and height of the triangular base hb

almond37 [142]

Answer:

116 cubic cm

Step-by-step explanation:

Volume of any pyramid is given by = 1/3(area of base* height of the pyramid)

To find the volume of given pyramid given are step

step 1:

Base of pyramid is triangular

base edge = 10 cm

height of triangular base = 8.7 ( This base is height of triangle and should not be confused with height of pyramid)

formula for area of triangle = 1/3(base * height)

substituting the value given above into the formula for area of triangle we have

area of base of pyramid = 1/3(10 * 8.7) = 29

____________________________________________________

step two : find the volume of prism

height of prism = 12 cm

Volume of any pyramid= 1/3(area of base* height of the pyramid)

=> Volume of the given pyramid= 1/3(29* 12) = 116 cubic cm

Lucas is walking around the edge of the playground shown. How far will lukas have to walk when he finishes one loop around the p

Tanya [424]

Answer:

See Explanation

Step-by-step explanation:

Required

Determine how far he walked in one loop

This question is incomplete, as the playground diagram and dimensions are missing. However, I'll answer on a general terms.

What this question requires is to calculate the perimeter of the playground.

Assume that the playground is rectangular and the dimensions are: 2 meters by 3 meters.

The distance walked will be calculated using the following perimeter formula.

$Distance = 2(2m + 3m)$

$Distance = 2(5m)$

$Distance = 10m$

If it is a square with 5m as the length of one of its side, the distance would be:

$Distance = 4 * 5m$

$Distance = 20m$

So basically, all you need to do is calculate the perimeter of the playground.

NEED HELP!!!!!! How can speeding impact the government officials?

dexar [7]

Answer:

IF people begin to speed over the limit, it causes other drivers to get distracted. It will most likely end in a crash. The government has to issue fines, and put it on their record to make sure it doesn't happen again. The answer is the government is behind all the paperwork for YOUR doing.
