Answer:
C) y-2x=-5
Step-by-step explanation:
you want the equation y=mx+b. Your b is going to be where the line meets the y-axis, so 5. y=mx+5. Add 2x to both sides to get this form. y=2x+5. This might not make much sense sorry.
8430cm²
=2(63 x 30) + 2(25 x 30) + 2(63 x 25)
= 3780 + 1500 + 3150
= 8430 cm²
