Step-by-step explanation:
By Pythagoras' Theorem, 6^2 + 8^2 = x^2.
x^2 = 36 + 64 = 100, x = 10.
Answer:
d or 4x²-12x-9
Step-by-step explanation:
factoring d you get (2x-3)²
which is a perfect square trinomial so
d or 4x²-12x-9
Answer:
x = 34°
y = 15
Step-by-step explanation:
x + 146 = 180
x = 34°
4y + 8 + 5y + 3 + 34 = 180
9y + 45 = 180
y = 15
The answer is -8 (-8=2*-4)
