Bishwant thought of a number He doubled it and added 5.if
he got 13, find the number
thought.​

The number Bishwant thought of is 4.

Step-by-step explanation:

First, let's think about what we can eliminate.

If Bishwant doubled the number and added 5, getting 13--then the number he thought of is obviously less than 13, 12, 11, 10, 9, 8, and 7.

Now, let's do some trials!

6 + 6 = 12; 12 + 5 = 17 <-- Incorrect

5 + 5 = 10; 10 + 5 = 15 <-- Incorrect

4 + 4 = 8; 8 + 5 = 13 <--Ah!

4 is the answer! (If you have any questions about this riddle, feel free to comment--but, please stay respectful everywhere, all the time.)

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

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

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
