Find XY if XM = 20 − 2 x XM=20−2x , MY = 3 x + 5 MY=3x+5 , and MM is the midpoint of XY ‾ XY .

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag
