1) Factor out the coefficient 2: 2x^2+12x=4 => 2(x^2 + 6x) = 4
2) Complete the square of x^2 + 6x: x^2 + 6x + 9 - 9. Then:
2(x^2 + 6x + 9 - 9) = 4
3) Rewrite the square as the square of a binomial:
2( [x+3]^2 - 9) = 4, or
2([x+3]^2) = 22, or
2( [x+3]^2 ) - 22 = 0
The value of q is -22.
40x+30x=315
70x=315
315/70=
4.5 hours
12:00 noon + 4.5 hours = 4:30 pm
Answer:
slope = 1
Step-by-step explanation:
slope = (y2 - y1)/( x2-x1)
slope = -2-3/-3-2
slope = -5/-5
slope = 1
Answer:
Option B. f(2) = 12.0
Step-by-step explanation:
we have
we know that
The second term is f(2)
For n=2
substitute the value of n in the formula
we have
substitute
Sum means add so: 24 + 36 + 13 = 73
