Use the triangle angle theorem:
All interior angles of a triangle equal 180 degrees.
If you use the theorem you should get the first one 19,70,91
Let the width be w
Width = w
Length = w + 6
Area = a
a = w(w + 6)
a = w² + 6w
Answer: a = w² + 6w
2. They are both straight lines. The solution of a linear system is where the two lines intersect, and if they're both straight lines, then they can only cross once.
See the picture attached.
y = 6x - 4
Substitute the given x values to solve for y.
x = 1:
y = 6(1) - 4
y = 6 - 4
y = 2
1 = 2
x = 3:
y = 6(3) - 4
y = 18 - 4
y = 14
3 = 14
x = 10:
y = 6(10) - 4
y = 60 - 4
y = 56
10 = 56
x y
