Answer:
3(2 - y)(2 + y)(4 + y²)
Step-by-step explanation:
48 - 3y⁴
Take 3 common:
3(16 - y⁴)
16 is 4² and y⁴ is (y²)²
3(4² - (y²)²)
Using a² - b² = (a - b)(a + b)
3(4 - y²)(4 + y²)
Again, 4 = 2²
3(2² - y²)(4 + y²)
3(2 - y)(2 + y)(4 + y²)
Answer:
A: 12
Step-by-step explanation:
Using the pythagoreom theorem, a^2+b^2=c^2. We can plug in the lengths of 5 and 13 which is 5^2+b^2=13^2. Now we can square the numbers to get 25+b^2=169. Subtract 25 from 169 to get 144. Now find the square root of 144 which is 12.
The answer is D.137
