The Absolute value bars act as the P in PEMDAZ (The P = Parenthesis but it really just means any containing symbols ( (), {}, [], || ) so you distrubute -2 into the bars resulting in the numbers becoming negative then you follow the steps down :)

Step-by-step explanation:
The equation used to represent the height of the ball, h in feet after t seconds is expressed as
h = -16t^2 + 48t + 4
A) The height of the ball after 2 seconds would be
h = - 16 × 2² + 48 × 2 + 4
h = - 64 + 96 + 4
h = 36 feet
B)The equation is a quadratic equation. The plot of this equation on a graph would give a parabola whose vertex would be equal to the maximum height travelled by the rocket.
The vertex of the parabola is calculated as follows,
Vertex = -b/2a
From the equation,
a = -16
b = 48
Vertex = - - 48/32= 1.5
So the ball will attain maximum height at 1.5 seconds.
C) The maximum height of the ball would be
h = -16 × 1.5² + 48 × 1.5 + 4
h = - 36 + 72 + 4
h = 40 feet
Answer: perimeter = 6x+15
EXPLANATION
The perimeter of the triangle is the distance around the triangle.
We need to apply our ability to convert word problems in to mathematical expressions.
we were told that the bottom of the triangle is units.
From the diagram perimeter
Four times the length of the bottom will be .
12 more than 4 times the bottom will be
Hence another side of the triangle is
Finally we were told that the last side is 3 more than the bottom, that will be
