What is the factored form of 3x + 21x-24?
anastassius [24]

Answer:

factorize form of the equation is  24(x-1)=0  , where  x=1

Step-by-step explanation:

Given Equation:

                        3x + 21x-24=0    

  Adding the terms of 'x' and taking constants on the other side.                        

                    24x-24=0

The sign of the constant will change on changing the side of it.                

                         24x=24

                           x=\frac{24}{24}

                            x=1

So, the value of  'x' is 1

The factorized form of the equation can be made by taking the common value from the equation i.e  

                      24x-24=0\\

                   24(x-1)=0

I need help with the photo below.
PSYCHO15rus [73]
Here, 30/360 * 2πr = 10
1/12 * 2 * 3.14 * r = 10
r = 10*12 / 6.28
r = 19.11

Now, Area = 1/12 * 3.14 * (19.11)²
= 3.14/12 * 365.16
= 95.5 Ft²

In short, Your Answer would be Option C

Hope this helps!
