Answer: -13w - 7
Step-by-step explanation:
-6w + (-8) + 1 + (-7w)
Combine the like terms
-8 + 1 = -7
-6w + (-7) + (-7w)
-6w + (-7w) = -13w
-13w + (-7)
However, because adding a negative number is the same as subtracting the number as a positive, you can just make it -13w - 7
Add 4 they were supposed to subtract 4. The subtraction sign is actually represented as a negative 2x. I think..
This equation in word form would be 7x -6 = -20, and the solution to that equation is x = -2
Answer: 12
Explaining: 2 times 4 is 8 so makes it reasonable to say 3 times 4 is 12. Also both of the triangles are similar just the left is smaller and the right is larger.
The answer is -22! Good luck! :DD
