Answer:

Step-by-step explanation:

40a²b =  2* 2 * 2 * 5 * a² * b      =  2³ * 5 * a² * b

48ab⁴ = 2 * 2 * 2 * 2 * 3 * a *b⁴  = 2⁴ *  3 * a * b⁴

LCM = 2⁴ * 3 * 5 * a² * b⁴

       = 16 * 3 * 5 * a² * b⁴

       = 240a²b⁴

Can u solve the answer

Answer:

She needs 50 ft² of wood to cover the table

Step-by-step explanation:

You need to know the formula for area of a trapezoid, which is

A = (B1 + B2)h/s     (add the bases together, multiply by the height, then divide

                                by 2)

We are given B1 = 12, B2 = 8, and h = 5, so plug them in and simplify

A = (12 + 8)(5)/2

 

    A = (20)(5)/2

       A = 100/2

         A = 50 ft²
