Y=16x²/9 ....................................
B is the correct answer to this question
Answer:
A
Step-by-step explanation:
the standard form of a quadratic equation is
ax² + bx + c = 0 : a ≠ 0
obtain (5 + x)(5 - x) = 7 in this form by expanding the factors
25 - x ² = 7 ( subtract 7 from both sides )
18 - x² = 0 ( multiply through by - 1 )
x² - 18 = 0 ← in standard form
with a = 1, b= 0 and c = - 18 → A
Answer:

Step-by-step explanation:
equation of a circle

we know the center is (-7, 3)
the radius is 2
we replace (h,k) with the center coordinates
and input the radius

simplify to this:

The midpoint of a line divides the line into equal segments.
The option that proves PQ = LO is (a)
The given parameters are:




P is the midpoint of LM.
So, we have:



Q is the midpoint of NO.
So, we have:



Distance PQ is calculated as follows:

This gives:



Distance LO is calculated as follows:



So, we have:


Thus:

Hence, the correct option is (a)
