Answer:
√x^2-4
Step-by-step explanation:
Given the expression
√(x+2) * √(x-2)
= √(x+2)(x-2)
Expand
= √x(x)-2x+2x-2(2)
= √x^2-4
Hence the product of the expression will give √x^2-4
For x to be acceptable x^2 - 4 = 0
x^2 = 4
x = ±√4
x = ±2
Acceptable value of x are values that are greater than or equal to ±2
Answer:
X= 11 Y= 7 Z= 55
Step-by-step explanation:
125+ z= 180. Z= 55.
55+ (8x+37) =180. —> 92 +8x = 180. Subtract 92 from both sides. 8x = 88. Divide both sides by 8. X =11. 8(11) + 37 = 125 for that angle. Then 125+(6y+13) = 180 —>138 + 6y = 180. Subtract 138 from both sides. 6y= 42. Divide both sides by 6. Y = 7
Subtract 7 from both sides leaving you with
26=-2a
Divide -2 from both sides leaving to you then with
-13=a and this is the answer
