Answer:
2[(1 + 5x) (1 - 5x)]
Step-by-step explanation:
Given:
Expression
2 - 50x²
Find:
Factorization of the given expression
Computation:
2 - 50x²
By taking 2 as common
⇒ 2[1 - 25x²]
⇒ 2[(1)² - (5x)²]
We know that;
⇒ a² - b² = (a + b)(a - b)
In given expression;
⇒ a = 1
⇒ b = 5x
⇒ 2[(1)² - (5x)²]
2[(1 + 5x) (1 - 5x)]
Factorization of the given expression
2[(1 + 5x) (1 - 5x)]
Answer:
the blue whale weighs 143.5 more tons than an African elephant
Step-by-step explanation:
an adult blue whale is 300,000 pounds, an adult African elephant is 13,000 pounds
300,000 pounds = 150 tons
13,000 pounds = 6.5 tons
150-6.5= 143.5 tons
