musickatia [10]

Answer:

$36*x^6-24*x^3$

Step-by-step explanation:

We can simplify the expressio using the product rule. The exponents will add up when multiplied with each other:

$=12*x^2*(3*x^4-2*x)$

$=12*3*x^(2+4)-12*2*x^(2+1)$

$=36*x^(6)-24*x^(3)$

The answer is B

$36*x^6-24*x^3$

A flying squirrel lives in a nest that is 9 meters high in a tree. To reach a fallen acorn that is 4 meters from the base of the

Luba_88 [7]

Answer:

Flying squirrel have to glide is for 9.8 meters approximately.

Step-by-step explanation:

Here we can use Pythagoras theorem.

Height is 9 , base is 4.

We need to find the hypotenuse measure.

So, let's use Pythagoras theorem $a^{2} +b^{2}= c^{2}$

Plug in a as 9 and b 4.

$9^{2} +4^{2}=c^{2}$

Simplify the left side of the equation

$81+16=c^{2}$

$97=c^{2}$

Take square root on both sides.

c=9.8 meters.

The table gives the boiling point of water at different altitudes.

stich3 [128]

Slope = raise / run

(211.1 - 212.0) / (0.5-0) = - 1.8

(210.2 - 211.1) / (1.0-0.5) = - 1.8

(208.4 - 210.2) / (2.0 - 1.0) = - 1.8

You can check, the other points. The slope is constant because the function is a linear equation,

Answer: - 1.8
