Answer:
1, -1, -3
Step-by-step explanation:
6(x+x+2+x+4)=-18
6(3x+6)=-18
18x+36=-18
18x=-54
x=-3
so x=-3, x+2=-1, and x+4=1

Answer:

Step-by-step explanation:
The initial dimensions of the paper are:
(length)
(width)
After the paper is cut along the diagonal, we remain with a right triangle, of which the length and the width corresponds to the base and the height.
For a triangle, the area is calculated as

where
b is the base
h is the height
Here we have:

Therefore, the area of the triangle is:

Area of big rectangle =8x7=56cm²
area of small rectangle =5x4=20cm²
hence area of shaded region=56-20=36cm²
Answer:
x=5, y=10. (5, 10).
Step-by-step explanation:
12x+6y=120
4x+y=30
-------------
2x+y=20
4x+y=30
----------------
y=20-2x
4x+(20-2x)=30
4x+20-2x-30
2x-30-20
2x=10
x=10/2
x=5
4(5)+y=30
20+y=30
y=30-20
y=10
