<span>1) Solve for x:
2x=12
divide both sides by 2
2x/2 = 12/2
  x = 6


2) If x=10, what is x+2x+7?

</span>10 + 2(10) + 7 = 10 + 20 + 7 = 37

<span>3) A petting zoo always brings 5 goats to a birthday party. They also bring two chickens per guest. If there are 20 guests, how many animals in total will be brought?

</span>two chickens per guest and there are 20 guests
so 2 x 20 = 40 (40 chicken for 20 guests)

40 chicken + 5 goats = 45 animals

answer
45 animals in total

1) if 2x=12
so x=12/2
=6
2) if x=10
then x+2x+7
=10+(2×10)+7
=10+20+7
=37
3) it will be
5+(2×20)
=5+40
=45

a rock is thrown from the top of a tall building. the distance, in feet, between the rock and the ground x seconds after it is t
frez [133]

Answer:

1.5 seconds

Step-by-step explanation:

Since f(x) represents the distance from the ground to the rock (in feet), we just need to find the values of x for which f(x) = 340. Substituting f(x) = 340 into f(x) = -16x² - 4x + 382 gives us:

340 = -16x² - 4x + 382

0 = -16x² - 4x + 42 (Subtract 340 from both sides)

16x² + 4x - 42 = 0  (Multiply entire equation by -1, "flip" equation)

8x² + 2x - 21 = 0    (Divide entire equation by 2)

(4x + 7)(2x - 3) = 0  (Factor LHS)

4x + 7 = 0 or 2x - 3 = 0 (Zero Product Property)

4x = -7 or 2x = 3 (Subtract -7 and add 3 from/to both sides, respectively)

x = -\frac{7}{4} = -1.75 or  x =\frac{3}{2} = 1.5

x = -1.75 is an extraneous solution because in the context of the question, you can't have negative seconds so therefore, the final answer is 1.5 seconds.

Hope this helps!
