None of the above. To form a standard triangle, all 3 sides must be of equal length.
Answer:
that would be the third one 12 ft, 12 ft, 20 ft because the lengths of 12+12 have enough to reach the 20 length compared to 30+30 which would only equal 60 and no more making it a line.
D
Step-by-step explanation:
Let's solve your equation step-by-step.
x2+4=3x+8
Step 1: Subtract 3x+8 from both sides.
x2+4−(3x+8)=3x+8−(3x+8)
x2−3x−4=0
Step 2: Factor left side of equation.
(x+1)(x−4)=0
Step 3: Set factors equal to 0.
x+1=0 or x−4=0
x=−1 or x=4
