Write the next number in this pattern.10,11,20,21,30,31

40,41

Step-by-step explanation:

It starts out with 10 then it increses by 1 to 11 then it incresses by 9 to 20.

so with this information we can conclude that at 30 it will increese by 9 to 40 then by 1 to 41

answer: a.   one is a factor of every whole number since every number is divisible by itself.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
