T=2A+4
S=5A-8
If Tom and Sara are 10 years old,
10=2A+4
6=2A
3=A
Not sure though
Answer:
y = ±
Step-by-step explanation:
step 1: substitute 'x' for 'y'
x = y² + 3
y² = x - 3
last step: solve for 'y'
y = ±
E is the midpoint so it's HALF of DF
Since it's half that means DE and EF have the same length.
Therefore DE multiplied by 2 is DF.
Considering DF is the full length.
