I don't see a mistake. You solve in parentheses first, then you solve exponents. If the exponent is 0 in this context, the answer would be 0.
Answer:-2
Step-by-step explanation:
Answer:
4x - 4y - 7z
Step-by-step explanation:
x - 3y + 4z + y - 2x - 8z + 5x - 2y - 3z =
(x - 2x + 5x) + (y - 3y - 2y) + (4z - 8z - 3z) =
4x + (- 4y) + (-7z) =
4x - 4y - 7z <===
Answer:
x = 26°
Step-by-step explanation:
The measure of the secant- secant angle x is one- half the difference of the measures of the intercepted arcs , larger subtract smaller
x = (66° - 14°) = 0.5 × 52° = 26°
