Perimeter

4x-7 plus 4x-7 plus 10x^2 + 4x - 2 plus 10x^2 + 4x -2.

8x - 14 plus 20x^2 + 8x - 4

<u>20x^2 + 16x - 18</u>

(x + 36) (x+10)

x = {36, 7}

gotta go, so I cannot do the rest. I hope that helps a bit.

Just add up the lengths of the four sides, and you have the perimeter.

The perimeter is:
(4x-7)*2 + (10x^2+4x-2)*2 =
8x-14 + 20x^2+8x-4 =
20x^2 + 16x - 18

Solve the inequality<br> 3/10 ≥ k - 3/5
balandron [24]

Answer:

The answer to your question is    k \leq  \frac{9}{10}   or    (-∞ , 9/10]                                      

Step-by-step explanation:

To solve inequality is similar to solve and equation, we just need to find the values of "k" in order than the inequality be true.

                                         k - \frac{3}{5} \leq  \frac{3}{10}

Solve for "k"

                                        k \leq  \frac{3}{10} + \frac{3}{5}

                                        k \leq  \frac{3}{10} + \frac{6}{10}

                                        k \leq  \frac{9}{10}

Then the answer is

                               k \leq  \frac{9}{10}   or    (-∞ , 9/10]

What is the volume of the rectangular prism? A prism has a length of 5 centimeters, height of 8 and one-half centimeters, and wi
nlexa [21]

Answer:

<em>Option D: 159 3/8 cm^3 </em>

Step-by-step explanation:

1. Let us rewrite the dimensions, and the options to make this a little more clear ~ (dimensions) 5 cm, 8 1/2 cm, 3 3/4 cm ⇒ (options) 17 1/4 cm^3, 18 3/4 cm^3, 27 1/4 cm^3, and 159 3/8 cm^3

2. To find the volume of most 3-dimensional figures, you would have to multiply the Base * height, so for a rectagular prism ⇒ <em>Base * height = length * width * height</em>

3. Substitute and compute the volume through algebra:

5 cm * 8 1/2 cm * 3 3/4 cm =

5 cm * 17/2 cm * 15/4 cm =

85/2 cm^2 * 15/4 cm =

1275/8 cm^3 =

<em>159 3/8 cm^3</em>

4. This means that the<em> Volume of the Rectangular Prism = 159 3/8 cm^3 (Option D)</em>
