Answer:

(x+3)(x+4)

Step-by-step explanation:

x²+7x+12

12 we can rewrite as a multiplication: 1*12 or 2*6 or 3*4

7 we can rewrite it as a sum of which 2 numbers you see above?...3+4

x² +3x+4x +12 , write 7x as 3x+4x

x(x+3) + 4(x+3) , factor x from first 2 terms x²+3x and 4 from last 2 terms 4x+12

(x+3) (x+4) , factor x+3

Answer:

60

Bill found a book he wanted on sale for $20.80. The original price of the book was $32. Find the discount rate.
Maurinko [17]

Answer:

35% discount

Step-by-step explanation:

We can first find what percent of 32 20.80 is.

This can be shown by using a percent proportion.

\frac{20.80}{32} = \frac{x}{100}

We can cross multiply to find the value of x.

20.80\cdot100=2080\\\\2080\div 32 = 65

So 20.80 is 65% of 32.

However, this is the percent of the original price. To find the discount, we have to subtract 65 from 100.

100 - 65 = 35

So the book was on a 35% discount.

Hope this helped!
