Answer:
4n-8=3n+4
Step-by-step explanation:
4n-8=3n+4
+8 +8
4n=3n+12
-3n -3n
n=12
Answer:
19/24
Step-by-step explanation:
3/8=36/96
5/12=40/96
36/96+40/96=76/96
76/96=19/24
Answer:
Part a) The length of the rectangle is 
Part b) The area of rectangle is 
Step-by-step explanation:
step 1
Find the length
Let
L-----> the length of the rectangle
W---> the width of the rectangle
we know that
The perimeter of rectangle is
so
----> equation A
-----> equation B
substitute equation B in equation A
solve for W
Find the value of L
step 2
Find the area
The area of rectangle is equal to
substitute the values
True. A rational number is a number that can be put into a fraction and all real numbers can in the form of x/1
Answer: Between <u>2</u> and <u>2.5</u> seconds
How am I getting those values? Those values are selected from the 't' column on the left side of the table. These are time values in seconds. Note how t = 2 corresponds to h = 0.4; while t = 2.5 corresponds to h = -10.6
The change in sign for the height, from positive to negative, means that the height h must be zero at some point between t = 2 seconds and t = 2.5 seconds. We don't know where exactly, but we know that h = 0 at least once in this interval. This is because the height is a continuous function. There are no jumps or gaps in the height (the object can't teleport or anything)
