If the function h(x) is defined as vertical stretched by a factor of 2 followed by a reflection in the x-axis of the function f(x) then h(x)=

the first one

step-by-step explanation:

just id the test.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

pls refer ro the top for answer

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
