Answer:
9409
Step-by-step explanation:
Let's rewrite 97 as 100 - 3.
Identity used :
<u><em>(a - b)² = a² - 2ab + b²</em></u>
Now, evaluating the expression :
⇒ (100 - 3)²
⇒ (100)² - 2(100)(3) + (3)²
⇒ 10000 - 600 + 9
⇒ 9400 + 9
⇒ 9409

Answer:
30
Step-by-step explanation:
30/100 *150
30*15/10
450/10
45
The formula for rate is distance (D)=r(rate)/t(time) so it would be 637.5=150/t and you would solve for t
