Find two numbers whose gcf is 90

180 and 90

Step-by-step explanation:

We are given that gcf of two numbers is 90.

We have to find those numbers which gcf is 90.

GCF: It is also called HCF.It is highest common factor of two numbers

Suppose , we have a=8 and b=4

HCF=

If GCF=90

HCF=

Therefore, the numbers are 90 and 180 whose gcf is 90.

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.
