Answer:
a = 35
c = 85
Step-by-step explanation:
85 + 60 + a = 180 as they are all supplementary angles (together they form an angle of 180°)
therefore a = 35.
a + ( 180 -(a+85)) + c =180 (as the angles of a triangle add up to 180°. our triangle is NMT, the angles are a, c and 180°-(a+85°) for a theorem about lines secant to parallel lines)
therefore c = 85
-8
2(4) is 8, and because you are multiplying a negative by a positive, the result is negative.
Answer:
In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.

Answer:
x=2, x=-2
Step-by-step explanation:
3x²-3+4x²-12=13
7x²=13+12+3
7x²=28
x²=4
x=-2
x=2
a. 21.141 for this pi is 3.14 so you add that and 18
b. 6.75 for this one the square root of 25 is 5. you just add 5 and 1.75
c. 7.232 sqaure root of 3 is 1.73 so add those too
d. 4.5558 pi is 3.14 and square root of 2
