Answer:
-2X-4 -3X-24
-2X-3X-24-4
-5X-28
Step-by-step explanation:
To find the perimeter of a square, just add up all the lengths of the sides: The area of a square: To find the area of a square, multiply the lengths of two sides together... Another way to say this is to say "square the length of a side!" and for the rectangle, The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.
46.8/0.002 = 23,400
Hope this helps!
Answer:
y = (-16t-2)(t-1)
To find the zeros, let's set y = 0 and separate these two expressions in parenthesis with the zero product property.
0 = -16t-2
0 = t-1
Now let's solve for t and get two zeros.
0 = -16t-2
2 = -16t
<u>t = -1/8</u>
0 = t-1
<u>t = 1</u>
1. Our two zeros are t = -1/8 and t = 1.
2. The two zeros are not both meaningful! Remember that this is modeling time, and we don't really care about -1/8 seconds. We don't need that negative time measurement, so we just want to know what's happening at 1 second. And at one second, the ball is on the ground. Great, so we know that height of ball = 0 after 1 second.
