What is the LMC for 2x^2 - 8x + 8 and 3x^2 + 27x -30?

Vsevolod [243]

Answer:

Step-by-step explanation:

1st step: solve the exponential number

2x^2=4x

3x^2=9x

2nd step: rewrite the number sentence with the exponent solved

4x-8x+8 9x+27x-30

3rd step : solve

4x-8x=-4x 9x+27x=36x

-4x+8= 36x-30=

4 6

Step 4: See what least common multiples they have in common

4 LCM =2 * 2= 4 6 LCM= 2*3=6

So the LCM is 2

Lynette buys candy at the grocery store. she gives half of the pieces to her son and 2 pieces to her daughter. if she has 4 piec

nevsk [136]

Let Lynette has originally candies in hand = x

She gave half to her son means x/2 given to son.

2 candies gave to daughter and left with 4.

x - x/2 - 2 = 4

adding 2 both sides

x - x/2 - 2 + 2 = 4 + 2

x - x/2 = 6

x /2 = 6

x = 12

Means she have 12 candies originally : Answer

Hope it will help :)
