The ratio of the number of marbles in box a to that in box b is 4: 3. if 1/2 of the marbles in box a are moved to box b, what will be the new ratio of the number of marbles in box a to box b? this is all about changing ratios by the way

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

4 inches will get you 10.16 centimeters, but you can either do 10.1 or round up to 10.2. good luck and hope this : )

3x^3-2x^2+4x-3= -3

x^2+3x+3= 3

-3÷3= -1
