Solve. 3x2 − 6x = 24 A) x = 2, x = 4 B) x = 3, x = 4 C) x = −2, x = 4 D) x = −4, x = 3

Oduvanchick [21]

3x^2 − 6x = 24
3x^2 − 6x - 24 = 0
3(x^2 - 2x - 8) = 0
3(x - 4)(x + 2) = 0
x - 4 = 0; x = 4
x + 2 =0; x = -2

answer
C) x = −2, x = 4

Help meee will give brainly! Find the domain of the function f(x)=5x−9 . DONT SAY I DONT KNOW

Agata [3.3K]

Answer and Step-by-step explanation:

$\frac{5}{x-9}$

The domain is all real numbers except 9 (positive)

This is because we can't have 0 in the denominator, and when x equals 9, then the denominator is 0. Anything divided by 0 is undefined, which is why 9 (in this equation) is not included.

Will mark brainliest help!

Answer:

52.5

Step-by-step explanation:

Since ED ≈ AD, ∆AED is a isosceles triangle where <EAD and <AED has same angle measurement

Now, m<B = 105°, since ABCD is a parallelogram, <B = <D

so, m<ADC = 105° so, m<ADE = 180°-105° = 75°

Now, m<EAD+m<AED+m<ADE = 180°

or, m<AED+m<AED+m<ADE = 180°

or, x+x+75°=180°

or, 2x=180+75°

or, 2x=105°

or, x=52.5°

Student Practice: Follow the steps in the example.

Sergio039 [100]

Answer:

1) Option B - 25.12 ft

2) Option C - 24.1 ft

Step-by-step explanation:

1) Given : The circular rug has a diameter of 8.2 feet.

To find : Which measurement is closest to the circumference of the rug in feet?

Solution :

The circumference of rug is given by $C=\pi d$

Where, d is the diameter = 8.2 feet.

$C=3.14\times 8.2$

$C=25.748\ ft$

The most closest measurement is 25.12 ft.

Therefore, option B is correct.

2) Given : A circle has a diameter of 5.2 feet.

To find : Which measurement is closest to the circumference of the circle in feet?

Solution :

The circumference of circle is given by $C=\pi d$

Where, d is the diameter = 5.2 feet.

$C=3.14\times 5.2$

$C=16.328\ ft$

The most closest measurement is 24.1 ft.

Therefore, option C is correct.
