What is the value of x?

Mathematics
1 answer:
katovenus [111]3 years ago
4 0

Answer:

x = 15

Step-by-step explanation:

Using the Altitude on Hypotenuse theorem

( leg of large Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse )

Thus

x² = 9 × (9 + 16) = 9 × 25 = 225 ( take the square root of both sides )

x = \sqrt{225} = 15

Which angles are linear pairs? Check all that apply.
AlexFokin [52]
Linear pairs are when 2 lines intersect, and are adjacent angles.

The measure of a straight angle is 180 degrees, so a linear pair<span> of angles must add up to 180 degrees.

-2k+13=-8k-35<br> What’s k
max2010maxim [7]

Answer:

k = -8

Step-by-step explanation:

-2k+13=-8k-35

Add 8k to each side

-2k+8k+13=-8k+8k-35

6k +13 = -35

Subtract 13 from each side

6k+13-13 = -35-13

6k = -48

Divide by 6

6k/6 = -48/6

k = -8

a rectangle has an area that is represented by 9x²-4. the length of the rectangle is 3x-2. what is the width?
PSYCHO15rus [73]

Step-by-step explanation:

the area is

length × width

(3x - 2) × width = 9x² - 4

to find width we could do a real polynomial division or simply recognize the fact that

(a + b)(a - b) = a² - b²

and we see that in our area calculation we are missing the (a + b) factor.

so, width = (3x + 2)

but if you want the division :

9x² - 4 : 3x - 2 = 3x + 2

- 9x² - 6x

-----------------

0 6x - 4

- 6x - 4

----------------------

0 0

again, width = (3x + 2)
