Answer:
(x+3) (x-4) aka x^2 - 1 - 12
Step-by-step explanation:
The weather forecaster means -5 +/- 10

The least possible temperature is -15 Celsius
4 2/7 30/7=4 with a remainder of two. The 2 goes as the numerator over the denominator of 7.
The problem ask to find the value of the cos(infinity) and the best answer, base on my further calculation and formulation that came up to a solution that leads me to an answer that the cos(infinity) is undefined but it has a range of (-1,1). I hope you are satisfied with my answer and feel free to ask for more
Answer:
x=4 x=-1
Step-by-step explanation:
x^2-3x-4=0
x^2-4x+x-4=0
x(x-4) + 1(x-4)=0
x+1=0
x=-1
x-4=0
x=4
