Log_(10)(x² - 4x + 7) = 2
Take the base 10 anti log of both sides.
x² - 4x + 7 = 10² = 100
x²- 4x - 93 = 0
Quadratic Formula
x = [4 ± √(4²-4(1)(-93))]/[2(1)] = [4 ± 2√97)]/2 = 2 ± √97
How am I supposed to know..... you think I'm smart.
A. -17.1
the minus sign makes the first number a negative, and a negative plus a negative you add normally but put a negative sign in your answer
Step-by-step explanation:
sin theta =p/h
sin 42=x/13
0.66×13=x
x=8.69
