Step-by-step explanation:
Option A is the correct answer
f(x)=8x+2
put x=-4
then out =8(-4)+2 = -32+2= -30
Yes it is a function Bc the x values don’t repeat
Area= 1/2 base x height
Area= 1/2 8x5
Area= 40/2
Area= 20cm^2
Answer:

Step-by-step explanation:
Start by making the denominators of both fraction the same. This can be done by multiplying one fraction's denominator by the other.
After simplifying and combining the two fractions together, check if the numerator can be factorised such that there is a common factor in the denominator and numerator. In this case, the numerator cannot be factorised.
Lastly, expand the denominator.
