Answer:
f(-5)=28
Step-by-step explanation:
f(x)=x²-2x-7
f(-5) means that we have to replace x by -5.
f(-5)=(-5)²-2(-5)-7=25+10-7=25+3=28
Answer: 1,904.92308 if you round it that will be 1904.9 or 1904.92

Step-by-step explanation:
Answer:
x = - 4, x = 2
Step-by-step explanation:
Given
3x² + 6x - 24 = 0 ( divide through by 3 )
x² + 2x - 8 = 0 ← in standard form
(x + 4)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
