What are the partial products that resault from multiplying 15×32​
Eva8 [605]

Answer:

Partial products are 300, 150, 20 and 10. The value of 15×32 is 480.

Step-by-step explanation:

We need to find the partial products of 15×32​.

First write each number as the sum of their place values.

15=10+5

32=30+2

Now, write 10 and 5 in first row, and 30 and 2 in first column as shown below:

                          10                           5

30              30×10=300              30×5=150

2                  2×10=20                   2×5=10

Therefore partial products are 300, 150, 20 and 10.

Add these partial product to get the value of product.

15\times 32 = 300+150+ 20+10

15\times 32 = 480

The value of 15×32 is 480.

2x^2+5x+3/x^2-3x-4 divided by 4x^2+2x-6/x^2-8x+16
Masja [62]

Answer: \frac{x-4}{2x-2}

Step-by-step explanation:

\frac{2x^2+5x+3}{x^2-3x-4} divided by \frac{4x^2+2x-6}{x^2-8x+16} is the same thing as multiplying \frac{2x^2+5x+3}{x^2-3x-4} by \frac{x^2-8x+16}{4x^2+2x-6}.

The equation we get is:

\frac{2x^2+5x+3}{x^2-3x-4}*\frac{x^2-8x+16}{4x^2+2x-6}

With this equation, we can factor each equation:

\frac{(x+1)(2x+3)}{(x+1)(x-4)} *\frac{(x-4)(x-4)}{2(x-1)(2x+3)}

We can cancel out like terms since they would be dividing each other:

\frac{x-4}{2x-2}
