Answer:
D
Step-by-step explanation:
They are all multiplied by 3 which is proportional
When you make the product of a binomial of the kind x + a times other binomial that is of the kind x - a, you obtain another binomial (not a trinomial), so any example with that form will be a counterexample that disproves the conjecture:
(x + a) * (x - a) = x^2 - a^2
For example, (x +3) * (x - 3) = x^2 - 9. So, not always the product of two binomials is a trinomial.
You would know when one number is also a multiple when the other number is a factor of it as well. For example when we see a prime number like 2, there are no factors for this number so it is just a multiple of 1 and 2.
However for numbers like 15 and 25.
We would know ( if you have your times tables memorized) that 15 is a multiple of 1,3, and 5 and 15. 25 is a multiple of 1, 5, and 25.
The three numbers are: 17, 88 and 22
Step-by-step explanation:
We need to find three numbers.
Let Third number = x
Second number = 4x (given in question: The second number is 4 times the third)
First number x-5 (given in question: The first number is 5 less than the third.)
And We are also given in question that:
The sum of 3 numbers is 127. i,e
Solving and finding x,
So, third number x = 22
Second number = 4x = 4(22) = 88
First number = x-5 =22-5 = 17
SO, the three numbers are: 17, 88 and 22
