Answer:
well i think the answer is B.
49x^2 = 36
take square roots of both sides:-
7x = +/- 6
x = 6/7, -6/7.
Answer:

Answer:
C. x = 1
Step-by-step explanation:
To solve this problem the best way is to use the quadratic formula. First make everything equal to 0 by adding 3 to both sides.
3x^2 - 6x + 3 = 0
The quadratic formula is:
. Substitute the values of a, b, and c into the formula. Keep in mind:

Therefore, x = 1.
Answer:
x = 32
y = 16sqrt(5)
z = 8sqrt(5)
Step-by-step explanation:
x/16 = 16/8
x/16 = 2
x = 32
y^2 = 16^2 + 32^2
y^2 = 1280
y = 16sqrt(5)
z^2 = 8^2 + 16^2
z^2 = 320
z = 8sqrt(5)
