Number 7 is not a factor of the number 49t + 30.
<h3>What is defined as the factor?</h3>
A factor is a number which divides another number by itself and leaves no remainder.
In other sayings, if multiplying 2 whole numbers yields a product, the numbers being multiplied are factors of a product because of product is divisible by them.
- Every integer has a limited number of factors.
- The factor of a number is often less than or equal to that number; it can never be greater than the number.
- With the exception of 0 and 1, each integer has at least two factors: 1 as well as the number itself.
- Division and multiplication are used to find factors.
For the given problem,
The equation is given as 49t + 30
For any value of t the number (49t will get completely divide by 7 leaving no remainder behind).
But 30 is not the factor of 7 as it will leave the remainder 2.
Thus, adding number 30 with 49t will result in a number which is not completely divisible by 7.
Thus, 7 is not a factor of number 49t + 30.

Answer:
f(x) = (x+10)^2 - 4
Step-by-step explanation:
vertex form is y = a(x-h)^2+k
to complete the square, we want to add a number on both sides so x^2+20x+whatver the number is, is the square of something
to find that number take 20, divide by 2, and then square it to get 100.
so, you would get f(x)+100 = x^2+20x+100+96
subtract 96 on both sides: x^2+20x+100 = f(x) + 4
factor: f(x) = (x+10)^2 - 4
