i ran through it by the other answer is wrong

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

the answer is 13 cm

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
