Factor 5 de 5t - 5
5(t - 1)
¡Espero que esto ayude! :)
Answer: The correct answer is Choice B.
To factor this expression, we should first factor out the variable x.
We will have:
x(x^2 + 4x - 5)
Now, all we have to do is factor x^2 + 4x - 5.
The factors of this are (x + 5)(x - 1).
If you put all of the factors together, you have: x(x + 5)(x - 1) or Choice B.
Answer:
Small no. is 15
Larger no. is 15 + 27 = 42
Step-by-step explanation:
Let the small no. be x
Larger no. will be x + 27
5x + x + 27 = 117
6x + 27 = 117
6x = 117-27
x = 90/6
x = 15
Answer:
No
Step-by-step explanation:
n₁=4
n₂=9
n₃=16
We can see that all three numbers are perfect squares of one higher than the figure number
So, n₁₅=(15+1)²=16₂=256
256≠225
