19x4=76
Answer:
Not a factor
Step-by-step explanation:
We can use Factor Theorem to answer this question. According to this theorem, in order to find if (x - a) is a factor of a polynomial f(x), calculate f(a). If f(a) comes out to be equal to zero, this will mean that (x-a) is factor of f(x).
Here, the expression we have is (x + 7), so we need to find f(-7) in order to check if (x+7) is a factor of f(x) or not

Substituting x = -7, we get:

Since f(-7) ≠ 0, (x + 7) is not a factor of the polynomial f(x)
To find how many cm are in a ft, you have to use the method of unit rate:
so we know that 12 in. equals a ft. so,
1 ft
------
12 in.
and 2.25 cm equals an in. so,
1 in.
-------
2.54cm
then we put the rates together and get:
1ft 1 in.
---- X -------................we cancel out the in. units and get:
12 in. 2.54 cm
Solve and get 1 ft = 30.48 cm
