Answer:

$(x-7)(x+4)$

Step-by-step explanation:

To factor the equation, break it into two binomials which multiply to make the equation. To write these binomials (x+a)(x+b), find factors which multiply to -28 and add to -3 for a and b.

28: 1,2,4,7,14,28

-7+4 = -3

$x^2-3x-28 = (x-7)(x+4)$

MatroZZZ [7]

Answer:

240.

Step-by-step explanation:

Here is the correct question: Three sister are getting new outfits. shirts cost 11 each,skirts coat 25 each and shoes cost 44 a pair. what is the total cost of the new outfits for all of the sisters?

Given: Cost of each shirt is 11

Cost of each skirts coat is 25

Cost of each pair of shoes cost is 44.

Now, finding total cost of shirt, skirt coat and shoes as cost of one new outfit.

= $11+25+44 = 80$

∴ Total cost of one new outfit is 80.

Next, finding cost of new outfit for all, three sisters.

Cost of new outfit for three sister = $\textrm { cost of one outfit}\times \textrm{ number of sisters}$

∴ Cost of new outfit for three sister = $80\times 3= 240$

240 is the total cost of new outfit for all the sisters.

4/3 is the ratio between fruit punch and orange juice. For every 3 cups of orange juice she makes, she can make 4 fruit punches. An example:
If you replace x (orange juice) with 2, that'd mean there'd be 6 cups of orange juice because you'd multiply 3 and 2. Same goes to 4. 4 multiplied by 2 is 8, which means if she makes 6 cups of orange juice, she can make 8 cups of fruit punch.
