प्रश्न
The sides of a triangle are 2x + 3y, x + 5y and 7x – 2y, find its perimeter.
उत्तर
Sides of a triangle are 2x + 3y, x + 5y, 7x - 2y
∴ Perimeter = sum of three sides of the triangle
= 2x + 3y + x + 5y + 7x - 2y
= 2x + x + 7x + 3y + 5y - 2y
= 10x + 8y - 2x
= 10x + 6y

Identify the numerical coefficient of term (other than constant) in the following expression:
5 − 3t2
Constant is only 8 other is variable a3 – 3ab2 x c
Subtract the second expression from the first:
a2 + ab + c2, a2 - d2
Simplify: 6a – (- 5a – 8b) + (3a + b)
Simplify: a + (b + c – d)
Simplify: `10 – {4"a" – (7 – bar ("a" - 5) - (5"a" - bar(1 + "a")))`
Simplify: `7"a" ["8a" - (11"a" - (12"a" - bar"6a - 5a"))]`
