Answer:
g(f(4)) = 9
Step-by-step explanation:
Fill in gf(x) for where x is in g(x): (x-7)²
Then, fill in 4 for where x is: (4-7)²
Square it: (-3)²
9
Answer:
2x
Step-by-step explanation:
1.Put all of your variables together like (7x+5x+2x) and the other like numbers
2. you add up everything okay
3.when are solving dont put the ones that arent the same in the correct category
4.put both answers together and then subtract from the last number to both numbers
5.Lastly you have received your answer
A-1.5 yards
We can figure this out by using the formula of inches to yards. Which is divide by 36 so 54/36 is 1.5. So that is how the answer is solved.
I hope this helps!
there could be a calculator online to solve it
Let a and b be odd number.
Because they are odd, by definition:
a = 2n + 1
b = 2m + 1
If we add them up:
a + b = 2n + 1 + 2m + 1
= 2n + 2m + 2
= 2(n + m + 2)
= 2k where k = n + m + 2
therefore a + b is always even.
