Lorelei evaluates the expression to determine how many different groups of ten she can make out of twelve items. her solution: subtract within parentheses and simplify: expand: divide out common factors: because 6 divided by 2? 1 is 3, there are 3 ways to choose the groups. which statements describe lorelei's solution? check all that apply. her work is correct. her answer is correct. in step 1, the subtraction cannot be completed before the factorial of each number is calculated. in step 1, 12! divided by 10! is not equivalent to 6! divided by 5! . in step 3, the dividing out of common factors was performed incorrectly. there are sixty-six ways to choose ten items from twelve.

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
