Step-by-step explanation:

With parallelograms like this, you an just multiply the width and length to find the area. If you cut the shape up in a certain way, it would make a rectangle, so the formula length*width=area would also apply to parallelograms.

In this diagram, what is ac?

Answers

Answer:

AC = 10 units .

Step-by-step explanation:

Given : Triangle ABC.

To find : What is AC.

Solution : We have given Triangle ABC.

Triangle BCD is right angle triangle .

By the Pythagorean theorem :

$(BC)^(2) = (BD)^(2) + (CD)^(2)$ .

Plug the values .

$(17)^(2) = (BD)^(2) + (8)^(2)$ .

289 = $(BD)^(2) + 64$ .

On subtractin g 64 from both sides.

289 - 64 = $(BD)^(2)$ .

225 = $(BD)^(2)$ .

Taking square root .

BD = $√(225)$ .

BD 15 units .

AB = AD+ BD

21 = AD + 15

AD = 21 -15

AD = 6 units .

Now , Triangle ACD is right angle triangle .

$(AC)^(2) = (6)^(2) + (8)^(2)$ .

$(AC)^(2) = 36 +64$ .

$(AC)^(2) = 100$ .

Taking square root

AC = 10 units .

Therefore, AC = 10 units .

$\sqrt{17 {}^(2) { - 8}^(2) } = 15 \n 21 - 15 = 6 \n \sqrt{8 { }^(2) } + √(6 ) {}^(2) = 10 \n c.10$

What is the greatest common factor of the terms of 3y2 – 21y + 36?

Answers

Answer:3

Step-by-step explanation:

Final answer:

The greatest common factor of the terms of the polynomial 3y2 – 21y + 36 is 3. This is because 3 is the highest number that can divide each term of the polynomial evenly and only the first two terms have 'y', so 'y' cannot be considered as a common factor for all terms.

Explanation:

The greatest common factor (GCF) of the terms of a polynomial is the highest number or variable that divides each term of the polynomial evenly. In this case, to find the GCF of the terms of the mathematical expression 3y2 – 21y + 36, we need to look at each term separately.

For the terms 3y2, -21y, and +36, the GCF in numerical terms is 3. However, since only the first two terms have y as a variable, y is not a common factor for all terms. Hence, the greatest common factor of the terms of the polynomial 3y2 – 21y + 36 is 3.
