An integer is one more than four times another. if the product of two integers is 39, then find the integers

The integers are 3 and 13

Step-by-step explanation:

Let the integers are x and y.

Then from the given directions we can frame two equations.

From equation 2, the value of x is

On substituting this value in equation 1, we get

Applying the quadratic formula, we get

Among these two values, 3 is an integer.

Hence, y= 3

The value of x is x= 39/3 = 13

Therefore, the integers are 3 and 13

Step-by-step explanation:

By Pythagoras' Theorem, z^2 + (2.7)^2 = (4.2)^2.

This means that z^2 = (4.2)^2 - (2.7)^2 = 10.35.

So z = 3.2 (1 d.p.)
