Answer:
B. A triangle can have only 1 right angle.
Step-by-step explanation:
Think of a right angle as an L. If you have an L connecting to a backwards L, you have an open shape. Triangles have 3 sides and are closed shapes. If a triangle has two right angles, you could connect the two ends but that would give you a square or triangle.
Hope this helped!
The first and the third one because they equal each other
2x+2=2(x+1) and 3(x-1)=3x-3
Answer:
(-2, 5/3)
Step-by-step explanation:
Step 1: Write out systems of equations
y = 2/3x + 3
x = -2
Step 2: Substitution
y = 2/3(-2) + 3
y = -4/3 + 3
y = 5/3
Step 3: Write solution
(-2, 5/3)
Answer:
x = 13
Step-by-step explanation:
(11x - 15) + (5x - 13) =180
16x -28 = 180
16x = 208
x = 13
15 is the greatest common factor.
