- the number 0 — additive identity
- a(b+c) = ab+ac — the distributive property
- an equation containing more than one variable — literal equation
- the number 1 — multiplicative identity
- the reciprocal of a number — multiplicative inverse
If x ≠ 0, then 1/x is its multiplicative inverse — true.
The product of a number and its multiplicative inverse is 1 — true.
Hi,
Let the
Youngest brothers age = x+2
Middle brothers age = x+4
Oldest brothers age = x+6
So,
Youngest brothers age = x+2 = 28+2 = 30 years of age
Middle brothers age = x+4 = 28+4 = 32 years of age
Oldest brothers age = x+6 = 28+6 = 34 years of age
Have a great day!
