Observe the squares... 13 is attainable owing to it being expressible as the sum of two squares (integers) 9 + 4.. utilize (0,3) and (2,0)... derive the square roots and assign them to different coordinate axes... for a more straightforward value. However, no such representation exists for 15... There is a representation available for 18... 18 = 3^2 + 3^2... try (0,3), (3,0), (3,6), (6,3).
The findings are probably not valid since it is improbable that the tires fitted in just one hour on Monday accurately reflect the whole population of tires.Step-by-step explanation: Out of 8 hours, do you truly believe that one hour could stand for all? This is the reason the results are likely invalid (I also participated in the quiz).
Cubing both sides of an equation is a reversible process. Detailed explanation: Squaring both sides isn't reversible because squaring a negative number produces a positive result, thus making it impossible to retrieve the original negative base, as square roots of negative numbers do not exist within real numbers. In contrast, cubic powers allow for reversibility; the cubic root of a negative number remains negative. For example, if we cube both sides and wish to revert to the original equation, we can do so using the cubic root on each side. Hence, cubing both sides is reversible.
Answer:
7 years
Step-by-step explanation:
Suri is 17 years old.
Her cousin's age is c.
Suri's age is stated to be 4 less than 3 times her cousin’s age.
This means we take 3 times her cousin’s age and subtract 4.
17 = 3c - 4
We now need to solve for c, which represents her cousin's age.
Add 4 to each side:
17 + 4 = 3c - 4 + 4
17 + 4 = 3c
21 = 3c
Now divide both sides by 3:
21/3 = 3c/3
7 = c
Thus,
Her cousin is 7 years old.
His annual savings over 52 weeks amounts to $867.
