Wirte a decimal for each of the following 9x100+2x10+3x0.1+7x0.001

borishaifa [10]

We need to perform multiplication and addition property for this problem to represent the final result in decimal form. So, the expression is,

9x100+2x10+3x0.1+7x0.001 .

Now 9 x 100= 900

2 x= 10= 20

3x0.1= 0.3

7x 0.001=0.007

Now we can all the numbers. Hence,

900+20+0.3+0.007=920.307

So, the decimal number is 930.307.

Foil (x+9)(3x-4) I have been stuck for ever

Bess [88]

Answer:

$3x^2+23x-36$

Step-by-step explanation:

The foil method is used when multiplying 2 binomials. One is (x+9) and another is (3x-4). The steps of FOIL are:

Multiply the first terms
Multiply the outer terms
Multiply the inner terms
Multiply the last terms
Combine like terms

Let's do the steps on our problem:

1. multiply x and 3x. So we have x * 3x = 3x^2

2. multiply x and -4. So we have x * -4 = -4x

3. Multiply 9 and 3x. So we have 27x

4. Multiply 9 and -4. So we have -36

Listing the terms, we have: 3x^2 -4x + 27x - 36

We combine like terms and have: 3x^2 + 23x - 36

That's our answer.
