The general formula for the sides of right triangle is
a² + b² = c²
Subtitute the equation of a and b to the formula a² + b², evaluate if the answer will be the same as the equation of c²
a² + b²
= (m² - n²)² + (2mn)²
= (m² - n²)(m² - n²) + (2mn)(2mn)
= (m⁴ - 2m²n² + n⁴) + 4m²n²
= m⁴ + 2m²n² + n⁴
Factorize the result
m⁴ + 2m²n² + n⁴
= (m² + n²)(m² + n²)
= (m² + n²)²
= c²
It's proven by the formula that c² = (m² + n²)²
so the c will be m² + n²
Answer:
£10.91
Step-by-step explanation:
72p is 1kg of potatoes
1kg of carrots is 62p
10kg of potatoes is £7.20 add 3 extra kg's
which is £2.16
add £2.16 with £7.20 = £9.36
2kg of carrots is £1.24 add an extra half of kg an you get £1.55
