Answer:
all real numbers or 
Step-by-step explanation:
since both f(x) and g(x) are polynomials, neither of them have restrictions on their domains. Since they can be defined for all real numbers. It's not like the square root which has a domain of (0, infinity), or log x which is defined only from (0, infinity). So adding these two polynomials would result in a domain of all real numbers.
Answer:
Step-by-step explanation
I think it is $170 a month.
Is subtracted 8,500-6,460 and that gave me 2,040.
I divided that by 12 and it gave me 170
Angles can be used to estimate the side lengths of a shape.
The letters in order of greatest to least are (a), (b) and (c)
The sum of angles at side (a) is:


The sum of angles at side (c) is:


The sum of angles at side (b) is:


So, we have:



The smaller the base angles, the longer the side.
Hence, the letters in order of greatest to least are (a), (b) and (c)

Area of a trapezoid
1/2(a+b)(h) where a and b are the parallel sides and h is the height.
a = 12.9, b = 8.6, h = 6.4
A = 1/2(12.9 + 8.6)(6.4) = 68.8 cm²
