Factor the algebraic expression -

7x+63=

7(x + 9)

Step-by-step explanation:

To factor this algebraic expression, you must take out the GCF (Greatest Common Factor) that 7x and 63 both have.

In this case, the GCF is 7, because 7x can be divided by it (giving you x), and so can 63 (giving you 9).

7x + 63 =

7(x + 9)

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

answer is x<
