Answer:
Step-by-step explanation:
With this question, we just have to group the terms, so in this case, we can remove the common term (x - 4), and then group the rest of them
If we do that we get:
(x - 4) (2x + 7)
Hope this helps,

2x + 3 = 9 Move all terms not containing x to the right side of the equation.
2x = 6 Divide each term by 2 and simplify.
x=3
Answer:
ill give you a idea to answer the question
Answer:
-15
Step-by-step explanation:
3^2 - 3 x [(5^2 - 9) / 2 ]
9 - 3 x [(25 - 9) / 2]
9 - 3 x (16/2)
9 - 3 x 8
9 - 24
-15
Answer: 6
SOLUTION
∵segment
is tangent to the circle at point C.
∴∠MCA=∠MCB=90°
Suppose 
From the Pythagorean theorem
MA²=9²+
²
MB²=4²+
²
∴MA²+MB²=AB²
i.e. 
We conclude that
