If you use metric conversion (shown below), you will find that 9 meters = 90 cm. Tell me if you need further explanation.
Answer:
-3x^2-22x-7
Step-by-step explanation:
You determine whether the parabola opens upward, with a positive x^2. It opens downward with a negative x^2.
f(x) is a maximum
g(x) is a minimum
the second one, and the third one
X2-2x-35=0x2-7x+5x-35=0x(x-7)+5(x-7)=0(x-7)(x+5)=0x-7=0 or x+5=0x=7 or x=-5 Check: x=7 ,LHS = 49-14-35 =0 =RHS x=-5, LHS = 25+10-35 =0=RHSAns: x=7 or x=-5
