I just took the test and the answer is
Answer:
7
Step-by-step explanation:
1. Lets Combine Like Terms. The only combineable terms are 8 and 8. So if we combine them they will equal 16. And we will have (2n+2)=16
2. Let's isolate the variable. We can do this by subtracting 2 from both sides. This will come out to 2n+14.
3. Let's further isolate the variable. We can do this by dividing both sides by two, which will finally come out to n=7
1....2470, 2474
2....2471,2473,2477
3.....340, 341, 342, 343, 344
Area of a triangle= bh/2b=4in h=8in8x4/2=16in
there are 4 triangles
4x16=64
area of a rectangle=bh
4x4=16
64+16=80in^2
Answer:
D
You use algebra and solve it for y.
Step-by-step explanation:
4x-3y=18
3y=4x+18
y=4/3x +6
