Step-by-step explanation:
Answer:
1. 5b^2-b-2 (so option 3)
2. 4x-1 (so option 2)
Step-by-step explanation:
For the first one you need to just simplify the expression
For the second one you need to combine like terms
Answer:
141
Step-by-step explanation:
The interior angles of a polygon with <em>n</em> sides is 180(<em>n</em> - 2) and the polygon has 7 sides, so the sum of its interior angles is 180(7 - 2) = 180(5) = 900.
125 + (x + 7) + 107 + (x - 15) + x + 131 + 122 = 900
Combining like terms,
3x + 477 = 900
3x = 423
x = 141
Answer:
9
Step-by-step explanation:
use the formula m = y2- y1 / x2 - x1
