Given that a side length is that means its parallel side is also 16. So 16 + 16 is 32 and 72 - 32 is 40 and 40 divided by 2, for two sides of the rectangle youll get 20. With the length being 20 and width being 16, 20 times 16 will get you 320m^2 which is the area.
Do you mean greater than or least than?
If you're not sure then here are them in greater and least than,
2.647 < 2.648 (Least than)
2.648 > 2.647 (Greater than)
Answer:
Harper is 17 and Cadence is 44.
Step-by-step explanation:
First, we can set up an equation to displays the sum of both ages.
Let x = Harper's age and y = Cadence's age
x+y=61
8 years ago, this means the sum will decrease by a total of 16 as we have to subtract 8 from both variables
The equation to represent 8 years ago is: x+y=45
Now we can write another equation to represent Cadence being 4 times older than Harper (8 years ago)
y=4x
We can substitute this back into the equation we had for the ages 8 years ago.
x+(4x) = 45
5x=45
x=9
Now, Harper's age 8 years ago is 9 years old. We add 8 to this number to determine that Harper is currently 17 years old.
We can insert this into the original equation to determine Cadence's age.
17+y=61
y=44
Thus, Cadence is currently 44 years old
