Describe how to find linear expressions for the possible dimensions of a rectangular prism with a volume of 8k^3 +26k^2+ 6k.

Mashutka [201]

8k ^ 3 + 26k ^ 2 + 6k
For this case, the first thing you should do is rewrite the expression.
We have then:
Step 1:
Take out common factor.
8k ^ 3 + 26k ^ 2 + 6k
2k * (4k ^ 2 + 13k + 3)
Step 2:
Factor quadratic expression.
2k * (4k ^ 2 + 13k + 3)
2k * (4k + 1) * (k + 3)
Answer:
to find linear expressions for the possible dimensions of a rectangular we rewrite the expression:
2k * (4k + 1) * (k + 3)

A store sold a case of scented candles for $17.85 that had been marked up 110%. What was the original price?

Salsk061 [2.6K]

$17.85 is 110% of the original price.

To find 1% divide this by 110:

17.85/110 = 0.16% (rounded).

Original price is 100% so 0.16*100 = $16.23 (rounded).

Check:

$16.23*1.1=$17.85 (1.1 is decimal equivalent of 110%).

Write the equation of a circle with center (-2, 0) and area = 64 pi

kozerog [31]

Answer:

The required equation in standard form is $(x+2)^2+y^2=64$

Step-by-step explanation:

The equation of a circle with center (h,k) an radius, r units is given by the formula;

$(x-h)^2+(y-k)^2=r^2$

The given circle has center (-2,0) and radius squared can be calculated from the given area, which is $64\pi$

$\pi r^2=64\pi$

$\implies r^2=64$

We substitute these values into the formula to obtain;

$(x--2)^2+(y-0)^2=64$

We simplify to get;

$(x+2)^2+y^2=64$
