Answer:
It can be almost ANYTHING but 2nd and 3rd length have to be bigger than 4
Step-by-step explanation:
You got the 1st length of the triangle, which is 4. And then we can "guess" what those length are. But whatever the length is, it won't be 0, and 2 length add up together will not be equal or less than 4, if you don't understand, draw it on the paper and you will get a straight line.
Answer:
x = -13, y = -3
Step-by-step explanation:
let a number = x; the other = y
x = 3y - 4
x + y = -16
Isolate the y in the second equation. Subtract x from both sides
x (-x) + y = -16 (-x)
y = -16 - x
Plug in -16 - x for y
x = 3(-16 - x) - 4
Simplify. Distribute 3 to all terms within the parenthesis
x = -3x - 48 - 4
x = -3x - 52
Isolate the x. Add 3x to both sides
x (+3x) = -3x (+3x) - 52
4x = -52
Divide 4 from both sides
(4x)/4 = (-52)/4
x = -52/4
x = -13
Plug in -13 for x in one of the equations:
x + y = -16
(-13) + y = -16
Isolate the x. Add 13 to both sides
y - 13 (+13) = -16 (+13)
y = -16 + 13
y = -3
Answers: x = -13, y = -3

Answer:
D
Step-by-step explanation:
4x - 2(x + 3) = 8
Use distributive property
4x -2x - 6 = 8
2x - 6 = 8
2x = 8 + 6
2x = 14
x = 14 ÷ 2
x = 7
