8.5 is the nearest one
square root of 72 is about 8.48
rounding to the nearest tenth gives you 8.5
Answer:
60 ≥ T ≥ 52
Step-by-step explanation:
The temperature will never be more than 60°, but no less than 52°. So we would use the "more than or equal to" symbol (≥) on the left of T to show that the temperature (T) will be less than or at 60°. And we use the "less than or equal to" (≤) on the right of T to show that the temperature (T) will be more than or at 52°. Hope this helps! Feel free to ask any questions!
Answer:
The answer is 40a+14c
Step-by-step explanation:
Step 1: Open the brackets
7a-9c+12a+33c+21a-10c
Step 2: Group all the like terms
Like terms are terms with similar variables, for example;
(7a, 12a, 21a) are all like terms since they have a common variable (a)
(-9c, 33c,-10c) are also like terms since they have a common variable (c)
Step 2: Solve
(7a+12a+21a)+(33c-10c-9c)=40a+14c
The answer is 40a+14c
Answer: 2a -5 + h
<u>Step-by-step explanation:</u>
f(x) = x² - 5x
f(a + h) = (a + h)² - 5(a + h)
= a² + 2ah + h² - 5a - 5h
f(a) = a² - 5a
f(a + h) - f(a) = a² + 2ah + h² - 5a - 5h - (a² - 5a)
= a² + 2ah + h² - 5a - 5h - a² + 5a
= 2ah - 5h + h²
= 2a - 5 + h
