Answer:
7d +d +d=45
Step-by-step explanation:
The length shown for the green line is shown as 45 therefore the black line also has 45
to prove your answer:
7d + d + d = 45
9d = 45
you need to get the letter d on its own so you
9d ÷9 = 45 ÷ 9 (what you do on the one side,you do on the other)

= 5+ 35 + 5
= 40 +5
= 45
