Answer:

The answer to your question is 9. (2x - 3)(3x - 4) 10. (x + 4)²

Step-by-step explanation:

9. 6x² - 17x + 12

-Multiply 6 by 12 and find the prime factors of the result

6 x 12 = 72

72 2

36 2

18 2

9 3

3 3

-Find two numbers that added gives -17

-These numbers are -8 and -9

-Substitution

6x² - 9x - 8x + 12

-Factor by grouping

3x(2x - 3) - 4(2x - 3)

(2x - 3)(3x - 4)

10. x² + 8x + 16

-Find two numbers that added gives 8 and multiply gives 16

-These numbers are 4 and 4

-Factor like a perfect square trinomial

(x + 4)²

Cade gets his phone bill and finds out that he is charged a 20 dollar flat rate and then must also pay .05 cents per minute. Wri

Klio2033 [76]

Answer:

1100 minutes

Step-by-step explanation:

Equation: 35=.05x-20

Why? x is the amount of minutes on his phone. Each minute is 0.05 hence 0.05x. Subtract 20 because that is the flat rate

55=.05x

x=1100

Therefore he was on his phone for 1100 minutes

All ratios remains same

$\\ \rm\hookrightarrow sinX=\dfrac{P}{H}=\dfrac{30.8}{34}=0.9$

$\\ \rm\hookrightarrow cosX=\dfrac{B}{H}=\dfrac{14.4}{34.4}=0.42$

$\\ \rm\hookrightarrow tanX=\dfrac{sinX}{cosX}=\dfrac{0.9}{0.42}=2.14$

Charlize wants to measure the depth of an empty well. She drops a ball from a height of 3 feet into the well

pentagon [3]

Answer:

about 151 feet

Step-by-step explanation:

The height of the ball at a time of 3.1 seconds is given by Charlize's equation as ...

h(3.1) = -16(3.1)^2 +3 = -150.76 . . . feet

The well is about 151 feet deep.

_____

Comment on this measurement

The speed of sound is sufficiently slow that it will make a difference in the time Charlize records. She would get a more accurate measurement if she were able to see the ball hit bottom.
