Answer:
B 65 sq. units
Step-by-step explanation:
The area of a triangle is equal to base times height divided by 2
the base is 13 and the height 10
13 times 10 is 130. 130 divided by two is equal to 65
So right now you see that you have x and y intercept right? Then plug those intercepts in equation that you have and solve for z. Which means z=5(1)(1) will be 5, 5(4)(1) will be 20, and 5(1)(2) will be 10. So, overall you have 5, 20, 10.

Step-by-step explanation:
Answer:33
Step-by-step explanation:
x-y=4 or x=y+4
2x=3y+3 or x=1.5y+1.5
x=y+4 and x=1.5y+1.5 so
y+4=1.5y+1.5 or 2.5=0.5y or y=5
plug y=5 into x=y+4 and you get x=9
plug in y=5 and x=9 into 2x+3y and you get 2*9+3*5=18+15=33
