Simplify combining like terms: 21b - 32 + 7b - 20b

Simplify combining like terms: 21b – 32 + 7b – 20b

Simplify combining like terms: 21b-32b+7b-20b

Simplify combining like terms: p-(p-q) -q-(q-p)

Simplify combining like terms: p - (p -q) - q - (q - p)

Simplify combining like terms: p – (p – q) – q – (q – p)

Simplify combining like terms and find q if p=2: p − (p − q) − q − (q − p)

In an AP the pth term is q and the (p+q) th term is zero, then the qth term is (i) -p (ii) p (iii) p+q (iv) p-q

Simplify (p vv q) ^^ (p vv ~q) .
