I rounded 9.27 repeating to 9.28 to make it easier to solve. It would be 232/25 as an improper fraction and 9 and 7/25 as a mixed number.
Answer:
4x-15
Step-by-step explanation
You just multiply -5 and -3 to simplify this.
Answer:
no because for right angle triangle the sum of the sq of the two smallest side is equal to the sq of biggest side
Answer:
-3.
Step-by-step explanation:
= 6(Sum+8) = 30
= 6Sum + 48 = 30
= 6Sum = -18
= Sum = -3
Hope this helps you :)
You just have to plug in each thing:
So f(0):
3(0)^2 - 4 = -4
so its not A
f(-2) and f(2):
3(-2)^2 - 4
3(2)^2 -4
now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4
B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.
