Which polynomial expression represents a sum of cubes? (6 – s)(s2 + 6s + 36) (6 + s)(s2 – 6s – 36) (6 + s)(s2 – 6s + 36) (6 + s)

Nadusha1986 [10]

Answer:

Option 3 is correct that is $(6+s)(s^2-6s+36)$

Step-by-step explanation:

We have general formula for sum of cube which is

$a^3+b^3=(a+b)(a^2+b^2-ab)$

Here, we have a=s and b=6

on substituting the values in the formula we will get

$6^3+s^3=(6+s)(s^2+6^2-6s)$

After simplification we will get

$6^3+s^3=(6+s)(s^2+36-6s)$

After rearranging the terms we will get

$6^3+s^3=(6+s)(s^2-6s+36)$ which exactly matches option 3 in the given options.

Therefore, option 3 is correct that is $(6+s)(s^2-6s+36)$

Point slope graph y+2÷4(x+5)

ladessa [460]

Answer:

See attachment for graph

The slope intercept form is $y=4x+18$

Step-by-step explanation:

Assuming you want to graph the straight line given in point-slope form as

$y+2=4(x+5)$

Then we need at least two points on this line

When we compare to the point-slope formula $y-y_1=m(x-x_1)$ then we obtain (-5,-2) as a point on this line so we plot it.

When x=0, y=4(0+5)-2=18 so we plot (0,18)

We then draw a straight line through as shown in the attachment.

On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:

$y+2=4x+20$

$\implies y=4x+20-2$

$\implies y=4x+18$

Please help me fast and show all your work please thx

choli [55]

Okay so the first thing you for for is to see if you can reduce your numbers and you can in this problem. You can reduce the 8 and 12 by 4, meaning that you can divide them by 4. So your problem would now be 2x7/3. Now to calculate your product you just times 2x7 and you’re answer is 14/3 :)
