Answer:
See below.
Step-by-step explanation:
Squaring a number means to multiply the number by itself.
For example, 3^2 means 3 * 3.
8^2 means 8 * 8.
(-6)^2 means (-6) * (-6).
In each case above, you see that the number that is squared is multiplied by itself.
In this case, (-4.5)^2, squaring the number -4.5, means multiply the number -4.5 by the number -4.5
(-4.5)^2 = (-4.5) * (-4.5)
Now we need to actually multiply -4.5 by -4.5
When you multiply a negative number by a negative number, the result is positive, so the product of -4.5 and -4.5 is a positive number. To find that number, you multiply 4.5 by 4.5
4.5 * 4.5 = 20.25
Therefore, (-4.5)^2 = 20.25
Well, there are 12 inches in a foot.
We have 3/12 inches (3 inches of a foot). Now, let's simplify!
What is the GCF (greatest common factor) of 12 and 3? Well, let's list out the factors (what a number divides into) of each of them.
1*12
2*6
3*4
1*3
The largest factor that we see in both of these numbers is 3, so let's divide 3/12 by 3!
3/3=1
12/3=4
So, 3 inches are 1/4 of a foot :).
You can check your answer by multiplying 12 by 1/4. Your answer will be 3!
I hope I helped! :)
Answer:
you have to figure out the number for X because X could be any number
Step-by-step explanation:
Put each variable's value in parentheses:
P = 2(2.5) + 2(3 2/5)
Solve and get P = 5 + 6 4/5 which as 11 4/5.
The mixed number answer is 11 4/5
