Answer: I got

5.8*5.8*5.8= 195.11

Step-by-step explanation:

The volume of a cube is found by multiplying the length of any edge by itself twice. So if the length of an edge is 4, the volume is 4 x 4 x 4 = 64

Or as a formula:  

volume = s3  

where:

s  is the length of any edge of the cube.  

Read as "s to the power 3"

Identify whether each of the following expression is a quadratic expression in one variable. Give reason for your anwser
ladessa [460]
I believe anything that is squared (^2) is a quadratic. so a, b, e and f are quadratics. you could also check on desmos to see if they are parabolas (u shape).

What is the GCF of 15 and 30
anygoal [31]
The greatest common factor (GCF) of 15 and 30 is: 15

Factors of 15: 1, 3, 5, 15
Factors of 30: 1, 2, 3, 5, 6, 10, 15

The common factors between the two numbers are 1, 3, 5, and 15, but considering 15 is the highest number out of them all, it is the greatest common factor.

Marcie solved the following inequality and her work is shown below:. . −2(x − 5) − 12 ≤ 4 + 6(x + 3). −2x + 10 − 12 ≤ 4 + 6x + 1
BartSMP [9]

All steps that Marcie did are right, but she forgot to change sign in last step.

Consider the inequality

-2(x - 5) -12 \le 4 + 6(x + 3).

Then

-2x+10-12 \le 4 + 6x+18.

Group the numbers:

-2x-2 \le 6x+22.

Separate terms with x and without x in different sides:

-2x-6x \le 22+2.\\-8x\le 24.

The coefficient at x is -8 and it is negative, then dividing the inequality by -8 you have to change sign in opposite:

x\ge -3.

Answer: Marcie forgot to change sign in last step.

How does the length of the hypotenuse in a right triangle compare to the lengths of the legs?
gavmur [86]

we know that

In a right triangle we have

two legs and one hypotenuse

Let

a,b -----> the legs of the right triangle

c-----> the hypotenuse of the right triangle (the greater side)

Applying the Pythagoras Theorem

c^{2}=a^{2}+b^{2}

therefore

<u>the answer is</u>

The length of the hypotenuse squared is the length of one leg squared plus the length of another leg squared
