Step-by-step explanation:
Square root is equivalent to 1/2 power:

Square root of 9 is 3. Multiply the exponents by 1/2 to get:

Supposing you know about the derivative, notice that

so that when
, the limit is equal to
and the answer is A.
You are given the area of both cupboards.
The total area would be found by adding the two areas together:
3a^2 − 5y + 15 + 4a^2 + 5y + 5
Combine like terms:
3a^2 + 4a^2 = 7a^2
-5y + 5y = 0y
15 +5 = 20
The area of both cupboards would be 7a^2+20
• 47.51 seconds * 8 times = 380.08 seconds total
Answer:
Yes, because by dividing x by his equivalent y, you find a constant of proportionality being 10.
x / y = 10
Step-by-step explanation:
20 / 2 = 10
50 / 5 =10
60 / 6 = 10
70 / 7 = 10
