Answer:

1. C. Yes, because a sum of cubes can be factored

2a. false

2b. false

2c. true

2d. false (based on what is written in the equation; refer to step-by-step)

Step-by-step explanation:

1. Both 3 and 8 can be cubed, which is why x^3+8 can be factored (x+2)(x^2-2x+4)

2a. a^2-b^2 can be factored by the perfect square rule, so it should be (a-b)^2

2b. both terms are perfect squares, so you can factor, making it (a+b)(a-b)

2c. You can factor using the perfect square rule, making it (a+b)^2

2d. Most of what is in the equation is true, yet the correct solution would be (a-b)(a^2+ab+b^2)

Identify the factors of 9x^2+24x+16

Goryan [66]

Hi friend,

This is a perfect square trinomial.

It can be recognised because it is of the form:

a^2−2ab+b^2=(a−b)^2

with a=3x and b=4

9x2−24x+16=(3x)2−(2⋅(3x)⋅4)+42

=(3x−4)2

The perimeter of a rectangle is 46in and the diagonal is 17 in

dmitriy555 [2]

Answer + explaination

p=2*(L+l)=46

L+l=46:2

L+l=23

(L+l)^2=529

(L^2+l^2)+2l*L=529

D= V L^2+l^2= 17

L^2+l^2=289

so 289+2l*L=529

2l*L=529-289=240

l*L=240:2

A=120

Please answer this question i really want answers :(

Based on the hints of distinguishing between radical and non-radical numbers, we have the following lists:

$\sqrt{3}$ , $2.\overline{2}$ , 2.5, $\sqrt{5}$
3.01, $3.\overline{01}$ , $3.\overline{1}$ , $\sqrt{9}$
$-4.\overline{1}$ , - 4.1, 4.01, $\sqrt{17}$
- 2.5, $-\sqrt{5}$ , $\sqrt{6}$ , 2.5

<h3>How to order numbers from least to greatest</h3>

In this question we must order sets of numbers in ascending order. A hint consists in comparing non-radical numbers with the closest radical numbers whose results are integers.

In consequence, we obtain the following orders:

$\sqrt{3}$ , $2.\overline{2}$ , 2.5, $\sqrt{5}$
3.01, $3.\overline{01}$ , $3.\overline{1}$ , $\sqrt{9}$
$-4.\overline{1}$ , - 4.1, 4.01, $\sqrt{17}$
- 2.5, $-\sqrt{5}$ , $\sqrt{6}$ , 2.5

A hobby store marks up remote-controlled cars 25%. The original

aksik [14]

Answer: $37.50

Explanation:
1. Turn 25% into a decimal by removing the “%” and placing a “0.” in front of it. (0.25)
2. Multiply the decimal (0.25) by the original price of the car (30). (0.25x30=7.5)
3. Add 7.5 to 30 to get the answer. (7.5+30=37.5=$37.50)
