Answer:
Step-by-step explanation:
With two congruent sides the third side is greater against a greater angle.
<u>34 < 36, therefore:</u>
<u>And, the angle should have a positive value:</u>
<u>Combined, we get:</u>
Answer:
-9A · √(5yA)
Step-by-step explanation:
The coefficient -3 stays the same.
45 factors into 5·9, which is helpful because 9 is a perfect square.
Thus, √45 = 3√5.
y cannot be factored. It stays under the radical.
A³ can be factored into A² (a perfect square) and A.
Thus,
-3√(45yA³) = -3 · 3√5 · √y · A · √A, or
= (-3)(3)(A) · √(5yA), or
= -9A · √(5yA)
Answer:
x=12!
Step-by-step explanation:
Difference of two squares will be
16y^2 -x^2 = (4y -x)(4y +x)
so the second choice
Answer:
Step-by-step explanation:
Since 
have the same denominators, we add them first. We then add 
to the result.
