Smallest to biggest 0.43,3/7,43.8%,7/16
Snezhnost [94]
First, we need to convert all the givens to decimal numbers. This will ease the arrangement process.
0.43 is already given as a decimal
3/7 is equal to 0.428
43.8% is equal to 0.438
7/16 is equal to 0.4375

Now, it has become easy to arrange the givens from smallest to biggest as follows:
0.428 , 0.43 , 0.4375 , 0.438

Changing the decimals back to the given form, we will find that the arrangement from the smallest to the biggest is as follows:
3/7 , 0.43 , 7/16 , 43.8%

Marat540 [252]

Answer:

(x-5)(x+8)=x^2+3x-40

Step-by-step explanation:

So we have the expression:

(x-5)(x+8)

To multiply, distribute the left to the terms on the right:

=(x-5)(x)+(x-5)(8)

Distribute:

=(x^2-5x)+(8x-40)

Combine like terms:

=(x^2)+(-5x+8x)+(-40)

Simplify:

=x^2+3x-40

Therefore:

(x-5)(x+8)=x^2+3x-40
