The simplest form is 63/100 <span />
Answer:
A. 10 cm
Step-by-step explanation:
In a right angled triangle, a² + b² = c² where c is the diagonal or hypotenuse. If you split a rectangle diagonally into two right angle triangles, the a and b of both triangles would be the same length. Therefore, the c or diagonals would also be the same length - 10 cm.

Answer:
36) A, 396
37) D, 114 km per lit
Step-by-step explanation:
36) 404 - 8 = 396
37) 112 / 8 = 14
Answer:
The answer is 9
Step-by-step explanation:
Given that a = √3 + √2 and b = √3 - √2 . To be more easier, we do it one by one :
First, a² :
(√3 + √2)(√3 + √2)
= 3 + √6 + √6 + 2
= 5 + 2√6
Second, ab :
(√3 + √2)(√3 - √2)
= 3 - √6 + √6 - 2
= 1
Third, b² :
(√3 - √2)(√3 - √2)
= 3 - √6 - √6 + 2
= 5 - 2√6
Then, evaluate a² - ab + b² :
5 + 2√6 - 1 + 5 - 2√6
= 9
