(x+1)(2x+1)(x-2)
= (2x+1)(x+1)(x-2)
= (2x+1)(x² -x - 2)
= 2x³ - 2x² - 4x + x^2 - x - 2
= 2x³ - x² - 5x - 2
Answer: 2x³ - x² - 5x - 2
Answer: i am sorry but the picture wont load-
Step-by-step explanation:
Answer:
Step-by-step explanation:
3+x-3= - 5x
combine like terms
3 += 4
x -5x = -4x
then combine 4 and -4x
Answer:
$27.2
Step-by-step explanation:
A cake that costs $32 is on sale for 15% off and there are no taxes. Explain why the expression (0.85).32 represents the final price of the cake in dollars.
This is explained in the calculation below
= A cake that costs $32 is on sale for 15% off
The amount off the cake is calculated as
= 15% of $32
= 15/100 × 32
= $4.8
The amount he is paying for the cake =>$32 - $4.8
= $27.2
The above expression is obtained as
(0.85).32
= (100% - 15%) × 32
=( 1 - 0.15) × 32
= 0.85 × 32
= $27.2
The final price of the cake = $27.2
Answer:
$500
Step-by-step explanation:
substitute the values for X & S in the equation from part A:
y=20x + 0.15s
x=($20x25) + (0.15x$0)
= $500
