Factor 6x^3 + 33^2 - 63x

This factors out to 3x (x + 7) (2x - 3)=0.

First, notice that the greatest common factor of this set is 3x.

Once you factor that out, you have a quadratic 2x^2+11x-21=0.

You can solve this by factoring using the ac method, to find two factors whose product is -42 and whose sum is 11. These factors are 14 and -3. 

You can split the middle term b to write 2x^2+14x-3x-21=0.

Then, you can factor to write 2x(x+7)-3(x+7)=0 \\ (2x-3)(x+7)=0. Finally, don't forget the 3x from earlier!

This factors out to 3x (x + 7) (2x - 3)=0.

A grocery store is offering a sale on bread and soup. Khalil buys four cans of soup and loaves of bread for $11.67. Ronda buys e
Annette [7]

Answer:

a. The equation should be

4x + 3y = $11.67

8x + y = $12.89

b. The price of one can of soup and the price of one loaf of bread is $1.355 and $2.09

The calculation is as follows:

here we assume the soup be x and bread be y

So, the equations are

4x + 3y = $11.67 .........(1)

8x + y = $12.89.........(2)

Here we need to multiply by 2 in equation 1

8x + 6x = $23.34

8x + y = $12.89

5y = $10.45

y = $2.09

Now x should be

8($2.09) + y = $12.89

x = $1.355

Hope this helps :)
