Answer:
5
Step-by-step explanation:
thanks for the points
9 times 8 equals 72
72 plus 2 equals 74
74 minus 1 equals 73
your answer would be 73
2x^2 + 7x + 3 ; you multiple each the terms in the first set or parentheses by the other
Let the solutions be a and b.
a = -2; b = -10
a + b = -2 + (-10) = -12
ab = (-2)(-10) = 20
(x - a)(x - b) = 0
(x - (-2))(x - (-10)) = 0
(x + 2)(x + 10) = 0
x^2 + 10x + 2x + 20 = 0
x^2 + 12x + 20 = 0
-h = 12
h = -12
4k = 20
k = 5
If we simplify like terms on left and right sides we gwt
16x + 9 = 4x
Its B
