The answer is “122“ 180-58 = 122
Answer:
B. -1
Step-by-step explanation:
If we have a parabola whose equation is:

The line of symmetry is calculated as:

Now, we have the equation
and the line of symmetry is 
Where:

So, we can replace
by -4 and
by -2 and solve for
using the following equation as:

It means that the equation of the parabola is equal to:

Answer:
B.25
Explanation:
The figures are similar. This means that corresponding sides have the same ratio.
This helps us set up a proportion.
We know that ML corresponds with DC, which gives us the ratio
8/40
EF will correspond with NH; this gives us the ratio
5/x
The proportion is then
8/40 = 5/x
Cross multiplying, we have
8(x) = 40(5)
8x = 200
Divide both sides by 8:
8x/8 = 200/8
x = 25
