Answer:
X = - 2 or X = 2
Step-by-step explanation:
*completing the square*
X^2 - 4 = 0
X^2 = 4
X = +-√4
x = +-2
x= -2, 2
*factoring*
X^2 - 4 = 0
(x-2)(x+2) = 0
|. |
x = 2, x = -2
________________________________
(x-2)(x+2) = x(x+2) - 2(x+2) = x^2 + 2x - 2x - 4 = x^2-4
Answer:
<h2>
8.72</h2>
Reasoning:
(7^2)-(3^2)= (6.32^2)
(6.32^2)+(6^2)=(8.72^2)
I hope this helps and good luck
Answer:
B
Step-by-step explanation:
Answer:
how to find them
Step-by-step explanation:
1. The sine of the angle = the length of the opposite side. the length of the hypotenuse.
2. The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
3. The tangent of the angle = the length of the opposite side. the length of the adjacent side.
Y ÷ 2 • 4 – 10 ÷ x + 6 where x = 5 and y = 16
16÷2x4-10÷5+6=
32-2+6=36 so A
