using
<span>a^3 + b^3 = (a+b)(a^2 − ab + b^2)
</span>so
w^3 + 125z^3
= w^3 +(5z)^3
= (w + 5z)(w^2 - 5wz + 25z^2)
hope it helps
Step-by-step explanation:
<u>to </u><u>evaluate</u><u> </u><u>the </u><u>difference</u><u> </u><u>between</u><u> </u><u>them </u><u>so,</u>
<u>subtract </u><u>1</u><u>.</u><u>8</u><u> </u><u>by </u><u>5</u><u>.</u><u>1</u>
<u>so,</u>
<u>5</u><u>.</u><u>1</u><u> </u><u>-</u><u> </u><u>1</u><u>.</u><u>8</u><u> </u><u>=</u><u> </u><u>3</u><u>.</u><u>3</u>
<u>so </u><u>difference</u><u> </u><u>between</u><u> </u><u>them </u><u>is </u><u>3</u><u>.</u><u>3</u>

Answer:
1.4x10^-7
Step-by-step explanation:
For Problem 6
First we would divide the first numbers together so 7.84 / 5.6 = 1.4
We then would add the exponenites together so -3+-4=-7
Leading our awnser to be 1.4x10^-7
<span>the answer is ,Yes, at negative and positive x-coordinates. </span>
Before we can make sure that E is correct, we need to make the denominator is equal with questions and the choices or convert into decimal.
2/3 = 0.66
1/3=0.33
1/5=0.2
2/6=1/3 = 0.33
1/2 = 0.5
7/10 = 0.7
7/9 = 0.77
The question is :
2/3 < x < 7/9
0.66 < x < 0.77
We need to divide into 2 parts :
0.66 < x
x < 0.77
So we need to find the answer that x is greater that 0.66 and we got 7/10. And 7/10 is less than 7/9.
