Let X = smallest angle
largest 3x
middle=2x. add the 3 angles of any triangle and you get ,180
x+2x+3x=180
6x=180
x= 30
smallest =30
middle=60
largest=90
Answer:
x² + 8
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 2x² + 1 - (x² - 7)
= 2x² + 1 - x² + 7 ← collect like terms
= x² + 8
Answer:
Numbers greater than or equal to 0.
Step-by-step explanation:
The domain of this function is {x∈R | x≥0}, meaning that x can be anything greater than or equal to 0.
not possible because the area of a square is always a square of it's length and a square cannot be a prime number
Answer:
B
Step-by-step explanation:
The chances of the first student walking to school is 7/30.
Without replacement, there are 29 students left. Hence the chance of the second student walking to school is 6/29 of the original 7/30 chance.
![(\frac{7}{30} )(\frac{6}{29} )=\frac{7}{145}](https://tex.z-dn.net/?f=%28%5Cfrac%7B7%7D%7B30%7D%20%29%28%5Cfrac%7B6%7D%7B29%7D%20%29%3D%5Cfrac%7B7%7D%7B145%7D)
