Helloooo, Your answer for part A is 13 cm
You answer for part b is 2600
13 x 10 x 20 = 2600
(-1.5,3) Y=3 which is up 3 and a horizontal line and 2x+y=0 can be written as y=-2x so in order to get -1.5 you have to make y=3 cause y=3 and when you do that it should look like 3/-2=-2/-2x so x=-1.5
You should search it on youtube becouse pepople cant really explain or draw the shape to show you
Step-by-step explanation:
first inequality :
x + 2y ≥ 10
second inequality :
x - y ≤ -2
