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

Which linear function has the steepest slope?

miskamm [114]

Answer: The correct option is A.

Explanation:

The slope intercept form is,

$y=mx+c$

Where m is slope.

The point slope form is,

$y-y_1=m(x-x_1)$

Where m is slope.

On Comparing the first equation with slope intercept form, we get m = -8.

On Comparing the second equation with point slope form, we get m = -2.

On Comparing the third equation with slope intercept form, we get m = 7.

On Comparing the Fourth equation with point slope form, we get m = 6.

The steepest line have greatest absolute slope value.

Since the equation 1 has greatest absolute slope value,i.e., 8 therefore option A is correct.
