5. which of the following is a solution to x2 – x – 6 = 0?
a
b
c
d
-3
-2
-1
2

x² - x - 6 = 0

x²- (3 - 2)x - 6 = 0

x² - 3x + 2x - 6 =0

x(x - 3) + 2(x - 3) = 0

(x - 3) (x + 2) = 0

x - 3 = 0

x = 3

x + 2 = 0

x = -2

x= 3 and x = -2

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
