Answer:

r³ + 15r² - 10r - 4

Step-by-step explanation:

First, note you can remove the brackets, in this case they contribute nothing at all.

Then, group the like terms and add them, e.g., we have 3r³ and -2r², they add up to r³.

Finally, order them from greatest power of r to smallest power of r.

That's all!

A car entering the freeway accelerates from 10.2 m/s with a constant acceleration of 4.4 m/s 2 . What is the car's final velocit
Ilya [14]

Givens

a = 4.4 m/s^2 This is an acceleration and is positive.

vi = 10.2 m/s

t = 4.2 seconds

vf = ????? The cruising speed in this case is vf.

Formula

a = (vf - vi)/t Notice the 3 givens and what you seek determine the formula

Solve

4.4 m/s^2 = (vf - 10.2)/4.2 Multiply both sides by 4.2

4.4 * 4.2 = vf - 10.2

18.48 = vf - 10.2 Add 10.2 to both sides

18.48 + 10.2 = vf 8.28 is the second best answer.

28.68 = vf This is your cruising speed.

If Line DE is parallel to Line FG, and Line KL is perpendicular to Line DE, what is angle GCJ equal to?
Svetach [21]
∠JAL is 65° because vertical angle to ∠IAK
So angle ∠JAE is 90° - 65° (total angle measure is 90°)
∠JAE is 25°
Therefore ∠ACB is also 25° because alternate interior angles
And ∠JCG is 25° because vertical angles
