What multiplies to 4 and adds to 2?

Answers

Answer 1

Answer:

The numbers are $x=1{\pm√(3)i }\n$ which multiplies to 4 and adds to 2.

Let x and y be two numbers which is multiplied to 4 and adds to 2.

So, x×y = 4...(1)

x + y=2...(2)

So, y=2-x

Put y=2-x in (1), we get

x×(2-x ) = 4

$2x-x^(2) =4\nx^(2) -2x+4=0\nx=(2\pm√(4-16) )/(2) \nx=(2\pm2√(3)i )/(2)\nx=1{\pm√(3)i }\n$

Therefore numbers are $x=1{\pm√(3)i }\n$ which multiplies to 4 and adds to 2.

3 5\16 in decimal form

Answers

The decimalform is 3.312.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

Example:

22 + 3x + 4y = 7 is an expression.

23 + 4 is an expression.

2 - 6 + 8 is an expression.

We have,

$3(5)/(16)$

= $(48 +5)/(16)$

= $(53)/(16)$

This can be written as,

16 ) 53 (3.312

= 3.312

Thus,

The decimalform is 3.3125.

First you convert the whole number into a fraction. Since you already have a fraction of 5/16, convert 2 into 16th's, which would be 32/16. Add 5/16 to 32/16 and you have 37/16. Divide 16 into 37, and your result will be a decimal. Your final answer will be 2.3125. I hope this helps!
