1. B put 4 into the g(x) equation the result is your x for the f(x) equation
2. C reverse of what is stated above
Answer:
50ft^2
Step-by-step explanation:
area of triangle ABC=25ft^2
both triangle have equal area and all together it makes a rectangle ABCD so ,
rect. ABCD=25+25=50FT^2
Answer:

Step-by-step explanation:
Using quadratic formula

we will have two solutions.
2x^2 - x - 4 = 0
So, a=2 b=-1 c=-4, we have:

Finally, we have two solutions:

The answer is 11 when you add everything up it makes 44 divided by how many numbers there are so 44/4=11
