Answer:
The quotient is 2x^2 - x + 1.
Step-by-step explanation:
If x + 1 is the divisor in long division, then -1 is the divisor in synthetic division:
-1 / 2 1 0 1
-2 1 -1
----------------------
2 -1 1 0
The quotient is 2x^2 - x + 1. The coefficients were obtained through synthetic division.
8÷(3-(8÷3))
8 divided by 3 minus 8 divided by 3.
Make sure to include the brackets otherwise the answer will not work.
The original price was 725.
Explanation:
"36% less than" means taking 36% away from 100%. 100-36 is 64, so 64% remains when 36% is taken away. So, 64% of the original table's price is 464.
So, if the original price was x, 464=0.64x
Solve this by dividing both sides by 0,64:
725=x
So, the original price was 725.
Answer:
Step-by-step explanation:
Original rectangle
L = 2*w
w = w
New rectangle
2w + 4
w - 3
Area New rectangle
(2w + 4)(w - 3) = 600 Remove the brackets
2w^2 - 6w + 4w - 12 = 600 Combine the left
2w^2 - 2w - 12 = 600 Subtract 600 from both sides
2w^2 - 2w - 600 - 12 = 0 Combine
2w^2 - 2w - 612 = 0 This factors.
(w- 18)(w + 17) = 0
w + 17 will produce nothing useful. What is - 17 m ? Can you measure it?
w = 18
check
Original Triangle
w = 18
L = 36
Derived Triangle
L = 36 + 4 = 40
w = 18 - 3 = 15
LW = 600
