1 times 108 because the normal height for a skyscraper is usually way more than any of those
Given expression is x² - 121
This is called Difference of Squared terms, we have a formula that is given as :-
a² - b² = (a - b) · (a + b)
Now using the above formula in the given expression, we get :-
x² - 121
x² - (11)²
here a = x and b = 11
x² - (11)² = (x - 11) · (x + 11)
but it says that student gave the answer as (x - 11) · (x - 11).
So, student's answer should be (x - 11) · (x + 11) instead of product of two (x - 11) terms.
101 ÷ 5 = 20 with a remainder of 1
So 20 is your whole number and 1 becomes your numerator and 5 remains your denominator.
20 1/5
Hope this helps. :)
Answer:
2. 18 3. 220 4. 11 5. 9 6. 18
Step-by-step explanation:
The answer is 25 children and 75 adults. Equation 1: A+C= 100 and equation 2: 2c+3a= 275
25(2)=50 75(3)=225.
225+50=275
Also 75+25=100
