1 mile is equal to 5280 feet
Add 900 to it:
5280 + 900 = 6180
6180 is less than 6200, so 1 mile and 900 feet is less than 6200 feet.
Answer:
9,500,000 950,000,000
Step-by-step explanation:
Each number is 100 times the previous. Basically, add 2 zeros to get the next number.
- 9.5
- 950
- 95,000
- 9,500,000
- 950,000,000
Step-by-step explanation:
well,
(y - 7)² = (y - 7)(y - 7)
remember how to multiply 2 expressions ?
you have to multiply every term of one expression with every term of the other expression and sum the results all up (incl. considering their individual signs, of course).
so, when we do the multiplication, we get
(y - 7)(y - 7) = y×y - 7×y - 7×y + (-7)×(-7) =
= y² - 14y + 49
and that is clearly different to y² - 49
FYI
y² - 49 is the result of
(y - 7)(y + 7)
because
y×y + 7×y - 7×y + (-7)(7) = y² - 49
The answer to your problem is x=3
