Can a triangle have sides with the given lengths 1ft,5ft,11ft
Scilla [17]
Let a,b and c is side of a triangle where:
a = 1
b = 5
c = 11

a^2 + b^2 = c^2. if the following statement is right, then triangle have these side.

1^2 + 5^2 = 11^2
1 + 25 = 121
26 != 121 ( != means not equal to)

Therefore, triangle can't have side length of 1, 5 and 11 ft.

What is the solution to this system of linear equations? x − 3y = −2 x + 3y = 16
True [87]

Answer:

so x=5 1/3 and

y= -2 2/3

Step-by-step explanation:

x-3y= -2x+3y=16. First we need to move all variables to one side of the equation and whole numbers to the other side of the equation. I see

x-3y+2x-3y=16. -3y-3y equals to -6y. 2x+x=3x. so 3x-6y=16. Lets take out the -6y so our equation would be 3x=16. x would equal 5 1/3. Now lets put back -6y into our equation. Let's now substitute x as 0. 3 times 0 equals 0 so our equation would now be -6y=16 which equals to -2 2/3.

so x=5 1/3 and

y= -2 2/3
