Grace, Chelsea, And Roan Are Simplifying The Same Polynomial Expression. Which Students Work Is Correct

Answers

Answer 1
Grace is correct.

Chelsea has an error in the first step (it has to be 6 - 3x - 12x + 16 bc minus multiply by minus is positive)

Roan also has an error in the first step (has to be 6 - 3x - 12x + 16)

Question 10 (2 points)
Find the missing length.
a
2.1 cm
2.9 cm
I NEED HELPPPP PLSSSS ITS FOR A MASTERY TEST PLSSSS HELPPPP

Answers

Answer:

a = 2

Step-by-step explanation:

To find the missing length we can use the Pythagorean theorem. Also, because it's a right triangle it makes it the perfect candidate!

The Pythagorean Theorem states:

a^2 + b^2 = c^2

Next, we substitute the letters with our given numbers (keep in mind that c is the hypotenuse which is the side facing the right angle)

a^2 + 2.1^2 = 2.9^2

Finally, we solve our equation (hint: use the calculator if needed)

a^2 = 4 (your answer is not final yet. You have to take the square root of both numbers)

a = 2 (Now that's the final answer!)

Answers

Answer:

18 sides

Step-by-step explanation:

(N x 180) - 360 = 160N

180N -360 = 160N

Jesse needs to decide which metric unit he should use to weigh a bowl of books and documents.

First, think about the size and weight of the objects in the bowl.

Milligrams would be far too small of a unit. The books alone would probably weigh a few million milligrams. Even grams is really not ideal, since the total weight would be thousands of grams.
