Answer:
b = 87°
Step-by-step explanation:
In order to answer this question, we need to utilise an important angle fact which is <em>angles in a quadrilateral add up to 360° </em>
Using the information we can set up an equation to find the value of b
→ Form equation
63 + 140 + 70 + b = 360
→ Simplify
273 + b = 360
→ Minus 273 from both sides isolate b
b = 87°
One meter is 3.28 feet, so anything shorter than that. A basketball, maybe a very young child?

Use FOIL (First, Outside, Inside, Last)
x(x) = x²
x(9) = 9x
-2(x) = -2x
-2(9) = -18
x² + 9x - 2x - 18
simplify by combining like terms
x² + 9x - 2x - 18
x² + 7x - 18
x² + 7x - 18 is your answer
hope this helps
