5 0

Answer:

Step-by-step explanation:

If the smallest number is 'x', then the other number = x +1

x*(x+1)= 420

Use distributive property

x*x + x*1 = 420

x² + x - 420 =0   ------> this is the required quadratic equation.

dezoksy [38]

Answer:

x = − 1 ,   2 √ 3 /3 , and − 2 √ 3 /3

Step-by-step explanation:

3x^3+3x^2-4x-4=0

By factoring, I can get simpler equations to get the roots.

x + 1 = 0, or x = -1

√ 3 x + 2 = 0, or − 2 √ 3 /3

√ 3 x - 2 = 0, or 2 √ 3 /3

How to put percent into decimal
fiasKO [112]

Answer:

There are multiple ways to do so:

You can divide the number by 100 to convert it to a decimal

You could take your percentage and add a decimal two places to the left.

Examples of both:

For division its as simple as 75 divided by 100 = 0.75

If we are going to use the decimal method, lets say we have 45%, so we can do this:

45% =45.00

Move the decimal two places to the left.
