<h3>Answer: </h3>

about 1.768 seconds

<h3>Explanation:</h3>

Since the phone is <em>dropped</em>, the first equation applies. The final height is assumed to be zero, so we have ...

... h(t) = 0 = -16t² +50

... 16t² = 50 . . . . . . . . add 16t²

... t² = 50/16 . . . . . . . . divide by 16

... t = √3.125 . . . . . . . take the square root

... t ≈ 1.768 . . . . . . . . round to milliseconds

2 + 3(3x - 6) = 5(x - 3) + 15 I'm in Algebra 1 and I still can't seem to get this problem, I use Slader to find how to do this b
Wewaii [24]

Answer:

x = 4

Step-by-step explanation:

2 + 3(3x - 6) = 5(x - 3) + 15

Expand the parenthesis:

2 + 9x - 18 = 5x - 15 + 15

Simplify:

9x - 16 = 5x

Subtract 5x from both sides:

4x - 16 = 0

Add 16 to both sides:

4x = 16

Divide both sides by 4:

x = 4

The perimeter of the new m-phone is 16 inches. The phones length is 5.25 inches. What is the width of the phone
True [87]
Perimeter is all the sides added up together.
Divide 16 by 2, so that you can get just a measurement of the length and the width.

16/2 = 8

Since the length is 5.25, subtract that by 8.

8-5.25 = 2.75

The width of the phone is 2.75 inches.
