Answer:
(x, y) = (8, 6)
Step-by-step explanation:
given the 2 equations
2x - y = 10 → (1)
2x - 2y = 4 → (2)
rearrange equation (1) expressing y in terms of x
y = 2x - 10 → (3)
Substitute y = 2x - 10 in equation (2)
2x - 2(2x - 10) = 4
2x - 4x + 20 = 4
- 2x + 20 = 4 ( subtract 20 from both sides )
- 2x = - 16 ( divide both sides by - 2 )
x = 8
substitute x = 8 in equation (3)
y = (2 × 8) - 10 = 16 - 10 = 6
solution is (8 , 6)

Answer:
15.8
Step-by-step explanation:
First off, I think you mean area. You can't find the perimeter of a triangle with only two sides listed, neither can you find that side unless you have the perimeter.
1. Area of the triangle formula is axb/2= (9.9x3.2)/2, which when put in a calculator is 15.84.
2. Rounded to 1DP makes it 15.8
