|4b - 4| + |3 - b³| + 2b³
subtitute b = 2 to the expression
|4·2 - 4| + |3 - 2³| + 2·2³ = |8 - 4| + |3 - 8| + 2·8 = |4| + |-5| + 16 = 4 + 5 + 16 = 25
---------------------------------------------
|4b - 4| + |3 - b²| + 2b³
|4·2 - 4| + |3 - 2²| + 2·2³ = |8 - 4| + |3 - 4| + 2·8 = |4| + |-1| + 16 = 4 + 1 + 16 = 21
Answer: B and E

Hello!</h3>
In order to find the vertex of a parabola, we use the following formula:
Remember, a parabola looks like so:
Now we know what a and b stand for.
In this case, b is -4, and a is -1:
Simplify:
Divide:

Answer:
Step-by-step explanation:
Given the dimension of the homeowner's backyard to be width 18 yards long and length 16 yards long, the area of the rectangular backyard id expreesed as;
Area of rectangle = Length * Width
Area of the rectangular backyard = 18yards * 16yards
Area of the rectangular backyard = 288yards²
If they plan to put in a square pool with side length 5 yards long in the backyard, the area of the pool = 5yd*5yd = 25yd²
The remaining area that will contain the tiles = Area of the rectangular backyard - area of the pool
The remaining area that will contain the tiles = 288yd² - 25yd² = 263yd²
<em>Note that we cannot determine the amount of tiles they need to buy since we are not given the dimension of each tile to use</em>. The area needed for the tiles for the rest of the backyard is therefore 263yd².
Amount of tiles needed to buy can be expressed as 263/dimension of a tile.

Find the zero term:
Plug in 0 for n.
a = 8 + 3(0 - 1)
a = 8 + 3(-1)
a = 8 + (-3)
a = 5
Answer: 5
-------------------------------
Find the first term:
Plug in 1 for n.
a = 8 + 3(1 - 1)
a = 8 + 3(0)
a = 8 + 0
a = 8
Answer: 8
-------------------------------
Find the 40th term:
Plug in 40 for n.
a = 8 + 3(40 - 1)
a = 8 + 3(39)
a = 8 + 117
a = 125
Answer: 125
