Answer:
C
Step-by-step explanation:
Since all triangles' angles have a sum of 180 degrees, it can't be A, because that would make it 240 degrees. That leaves us with B and C. While B <em>could</em> be true, we don't know it for sure. Therefore, C is the correct answer because adding them should equal 60 degrees, which, adding them to the first angle (which was 120 degrees), would 180 degrees.
Answer:
a
Step-by-step explanation:
Well in the first you buy 5P+2B+3L
but then you buy 3P +1B+2L
and you add then up
"2x2 + 3x = −5" should be re-written as 2x^2 + 3x +5 = 0. This is a quadratic equation with a=2, b=3 and c=5. Thus, the roots are:
-3 plus or minus √(9-4[2][5])
x = ---------------------------------------------
4
or:
-3 plus or minus √(-31)
x = ----------------------------------
4
or:
-3 plus or minus i*√31
x = ----------------------------------

Answer:
10
Step-by-step explanation:
2/3x15
as 3 and 15 are multiples they can be cancelled.
so 2x5=10
