Answer:
Expression to represent the total number of balls:
T = 37 +16x
Step-by-step explanation:
Number of baseballs present in the summer camp = 14
Number of tennis present in the summer camp = 23
Number of boxes of tennis bought by the manager = x
Number of tennis balls in 1 box = 16
Number of new tennis balls bought = 16 × x
So, the expression of total number of balls in the summer camp = T
T = 14 + 16x + 23 = 37 +16x
X squared + 5x -6
X squared - 2x15
X squared -7x +12
Answer:
Step-by-step explanation:
In each case, you're looking for divisors of the constant that have a sum equal to the x-coefficient. Those divisors are the constants in the binomial factors.
1) -6 = -1·6 = -2·3 . . . . . (-1)+(6) = 5, so these are the constants of interest.
x^2 +5x -6 = (x -1)(x +6)
__
2) -15 = -1·15 = -3·5 = -5·3 . . . . . (-5)+(3) = -2, so these are the constants of interest
x^2 -2x -15 = (x -5)(x +3)
__
3) 12 = -1·-12 = -2·-6 = -3·-4 . . . . . (-3) +(-4) = -7, so these are the constants of interest
x^2 -7x +12 = (x -3)(x -4)
b)3+9i
c)7+16i
d)-1+2i
