Answer:
C. 41
Step-by-step explanation:
180 - 81 = 99
99+40 = 139
180 -139 = 41
Step-by-step explanation:
The Answer Is
-4d + 7 = 3d
So, 7 = 3d + 4d
Then, 7 = 7d
•d = 7/7
= 1
So D = 1.
The distance around an object is called the perimeter. To get the perimeter, you add up the sides. So, 2/18 + 3/12 + 2/12 = your answer.
-10d^2 + 11d - 2
To find this, distribute the - to 7d^2 - d - 6.
This will give you a new equation of:
-3d^2 + 10d - 8 -7d^2 + d + 6
Combine like terms to get the answer above.
Hope this helps!
