Answer:
(-2, 0)
Step-by-step explanation:
Use elimination: add the two systems. Because the left is equal to right, you are adding the same thing and it's legal.
-x+3y=2
+ (x+y=-2)
Add each term
-x+x + 3y+y = 2+ -2
4y=0
y=0
x+y=-2
x+0=-2
x=-2
Answer: 5931.8m^2
Explanation:
Explanation:
85.9 x 48 + 3.14 x 24^2
= 4123.2 + 1808.64
= 5931.8m^2
Triangle angles add to 180 degrees; geometry over.
x + 10 + x + 3x - 5 = 180
5x + 5 = 180
5x = 175
x = 35
