The sum of twice a number and 5 is at least 12. How do I write it?

3.5

Step-by-step explanation:

let x represent the number.

twice the number = 2x

2x + 5 = 12

2x = 12-5

2x = 7 ; divide both sides by 2.

x = 3.5

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
