Answer:
Sharon is 36
Her daughter is 7 years and 2 months
Step-by-step explanation:
sharon is 5× as old
her daughter is written as 1 (because we dont know about her age)
then square root of 256 to find square which is equal as said in the queston:which is 16
algebraic equation would be:5n+16 (n represents the years and 5 is how many times older sharon is and 16 is how old their square sum of agewas 4 years ago)
Their present age would be:
