1.

(Create a table then plot the points)


X | 0 | 1 | 2 | 3 |

-------------------------

Y | -1 | 3 | 7 | 11 |


4 (0) -1 => 0 - 1 = -1

4 (1) -1 => 4 - 1 = 3

4 (2) -1 => 8 - 1 = 7

4 (3) -1 => 12 - 1 = 11


Just apply the table method to the others and you should be fine! :)

26. If the area of the rectangle shown below is given by the expression 3x + 7x - 6,
Crazy boy [7]

Answer:

D=(3x-2)

Step-by-step explanation:

Area=length×width =3x²+7x-6

thus a=3 b=7 c=-6

W=(x+3)

since c is -6 it has to be the product of 3(from W)=-2

since a=3 multiply by x (from W) 3×x=3x

=3x-2

check if its correct.

3x-2×x+3

x(3x-2)+3(3x-2)

3x²-2x+9x-6

3x²+7x-6 thus its true
