Solve the equation for all real solutions.

Step-by-step explanation:

You can use the quadratic formula for any quadratic. The quadratic formula is given by , and yields both real and non-real solutions.

In the given equation , we have:

Substituting given values into the quadratic formula, we have:

The attempt in the problem is correct. Sometimes with auto-grading, the solutions need to be in a specific order to be marked correct. I'd suggest submitting the solutions in a different order to check if that's the issue.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

y > 1/3x

y < = -x + 4

hope this : )
