Question

a number is multiplied by half of itself and then 32 is added to the product.If the final rwsult is 130 then find the original number

Answer 1

let the no be x
x * 1/2x +32 = 130
1/2 x^2 = 98
x^2 = 196
x = 14

so the original no is 14 .
☺️hope it helps☺️

Answer 2

Let the number be x. Then,

x × x/2 + 32 = 130

= x × x/2 = 130 - 32 = 98

= x × x = 98 × 2

= x² = 196

= √x² = √196

= x = 14.
