Answer:
a = 29
b = 64
c = 87
Step-by-step explanation:
Let the angles be a (smallest), b, and c (largest).
We know that a triangle's angles must add up to 180 degrees, so we can construct the following equations.
a + b + c = 180
c = 3a
b = a +35
With some solving and substitution...
a + (a + 35) + c = 180
2a + c = 145
2a + (3a) = 145
5a = 145
a = 29
and therefore,
b = 29 + 35 = 64
c = 3(29) = 87
Answer:
x^3+9x^2-3x^2-3
Step-by-step explanation:
You can use a various of methods but when you use the box method you multiply each separately.
Like you would multiply x² by x, 8x by x, -3 by x (thats the first row)
x² by 1, 8x by 1, -3 by 1 ( for the second row)
Then you get those final variables and combine like terms getting the answer above

Answer:
Left apples = 2
Step-by-step explanation:
The given problem is "If pierino has 4 apples and eats two, what is left".
Total no of apples = 4
He eats 2 apples = 2
We need to find no of apples left.
Left apples = total no of apples - eaten apples
= 4 - 2
= 2
Hence, there are 2 apples left.
