8.6 * 7.5 divided by 2 is 32.25
Hi! Multiply -0.25 by the inner numbers.
-0.25 times 84 = 21
-0.25 times -32n = -8n
Then take the -n and add that
21 -8n - n
-8n - n (or -1n) = -9n
therefore, answer would be a) 21 - 9n
Answer:
the fist one is A and the second one is D
Step-by-step explanation:
Answer:
(f+g)(x) = x² - x + 6
Step-by-step explanation:
We can find (f+g)(x) by adding f(x) and g(x).
f(x) = x² + 1
g(x) = 5 - x
(f+g)(x) = f(x) + g(x)
(f+g)(x) = (x² + 1) + (5 - x)
(f+g)(x) = x² + 1 + 5 - x
(f+g)(x) = x² - x + 6
Answer: 180 is the sum of the tringles
Step-by-step explanation:
2x+7x+11x=180
20x=180
x=9
Now you should put the the value of x to get the angles
2x=2x9=18
7x=7x9=63
11x=11x9=99
Now to double check add all of them together
99+18+63=180
Hoped I helped!
