Sorry don’t know! Hope u find someone that does know
Step-by-step explanation:
I think what is meant in the triangle ABC we have the three angles.
the sum of all angles in a triangle is airways 180 degrees.
so,
180 = A + B + C
180 = 42 + B + C
now, we know also that
B = 5×C
so, we can use that above
180 = 42 + 5×C + C
138 = 6×C
C = 138/6 = 23 degrees
B = 5×C = 5×23 = 115 degrees
Answer:
-3x²+17x-20
Step-by-step explanation:
When you apply the distributive property (which you did correctly), you simply multiply each number or variable in which you have to distribute it to (which again you wrote correctly) and then you add them all together.
(3x)(-x)=-3x²
+
(3x)(4)=12x
+
(-5)(-x)=5x
+
(-5)(4)=-20
Add those and you will get your answer. Hope this helped :)
Answer: The sum =14
Step-by-step explanation:
Given that n=2
And
sum = cube of a number, n, and 16 which can be expressed mathematically as
n^3 + 6
2^3 + 6
8 + 6= 14
