2. 1/3
3. 112
Step-by-step explanation:
Answer:
a = 12
Step-by-step explanation:
<u>Pythagoras’ Theorem</u>
a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
From inspection of the triangle:
- leg a = a
- leg b = 9
- hypotenuse c = 15
Substituting these values into the formula and solving for b:
⇒ a² + 9² = 15²
⇒ a² + 81 = 225
Subtract 81 from both sides:
⇒ a² + 81 - 81 = 225 - 81
⇒ a² = 144
Square root both sides:
⇒ √(a²) = √(144)
⇒ a = 12
I believe that n represents the starting number. so if you replace n with 7 the expression should look like this :
2(7+8) = ??
you would first add what is in the parenthesis so :
2(15) = ??
then just multiply 2 x 15
Max's final number is 30.
