Explanation:

We can use the information given about the perimeter of the triangle to set up an equation:

PQ + QR + PR = 75

Substituting the given expressions for each side, we get:

(4y + 2) + (y + 3) + (5y) = 75

Simplifying the left-hand side, we get:

10y + 5 = 75

Subtracting 5 from both sides, we get:

10y = 70

Dividing both sides by 10, we get:

y = 7

Now that we know the value of y, we can substitute it back into the expressions for each side of the triangle to find their lengths:

PQ = 4y + 2 = 4(7) + 2 = 30

QR = y + 3 = 7 + 3 = 10

PR = 5y = 5(7) = 35

Therefore, the lengths of the sides of the triangle are:

PQ = 30

QR = 10

PR = 35
