Simple, solve straight across, its either 4n or 2n
I hope this helps you
3x-5+5=9+5
3x=14
x=4,66666....
Activity 3
1) 2m^2(4m^2 + 3m + 2)
2) (x + 4)^2 (x - 4)
3) (x + 9)(x - 7)
4) 5y(17y - 4z)
5) (2x - y)(6x + 5y)
Activity 4
1) 80 units because when you sub h = 9, you get 400 as the answer and because it’s a square, you square root 400 which is 20 units per side.
2) x = 7cm because when you multiply (x + 5)(x - 3), you get x^2 + 2x - 15 = 48 and when you solve it you get x is equal to 7, -9, because the length of the rectangle is positive x is equal to 7.
3) the binomial would be (9x + 1)^2.
Solution: We are given data points and associated residuals:
Data Point Residual Absolute value(Residual)
(20,6) -2.00 2.00
(15,5) 6.75 6.75
(5,3) -1.25 1.25
(10,10) 4.50 4.50
From the above absolute value(Residual) column, we clearly see the data point (15,5) has the residual with greatest absolute value of 6.75.
Therefore, the data point and its associated residual is:
(15,5) and 6.75
