Pleaa helll jack father 4 times old his son five years later both age diffrence is 10 find both age.

Step-by-step explanation:

Let Jack's present age be x

Hence, his fathers present age=4x

Jacks age after 5 years= (x+5)

Jacks Fathers age after 5 years= (4x+5)

We know.. that the difference between their ages fives years later is 10.. hence

4x+5-(x+5)=10

4x+5-x-5=10

3x = 10

x= 3.3 years old...

Hence,

Jacks present age = 3.3 years

Fathers present age= 13.2 years...

Hope it helps .. I know that the answer comes in decimals... but the questions' like that..

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

if you was gonna solve for a, a is a   < -12
