Answer:
The solution of given expression = 5 , -3
Step-by-step explanation:
Given expression;
15 - 4x = x² - 6x
Find:
The solution of given expression
Computation:
15 - 4x = x² - 6x
x² - 6x + 4x - 15 = 0
x² - 2x - 15 = 0
x² - (5 - 3)x - 15 = 0
x² - 5x + 3x - 15 = 0
x(x - 5) + 3(x - 5) = 0
(x - 5)(x + 3) = 0
So,
x - 5 = 0 and x + 3 = 0
x = 5 and x = -3
The solution of given expression = 5 , -3
Answer:
Fernado saves $90.
Step-by-step explanation:
40% of $150 ( original price ) = $60
$150 - $60 ( original price - discounted price ) = $90 ( savings )
The question asks about the 40% markdown only, so I'd assume you wouldn't reduce it by $25.
But if you did Fernando would save $115 :
40% of $150 ( original price ) = $60
$60 - $25 ( mail-in rebate ) = $35
$150 - $35 ( original price - discounted price ) = $115 ( savings )
Answer: 2x2(2x+1)(2x-1)
