Answer:
Step-by-step explanation:
f(x) = (x - 4)(x + 2)
f(x) = x^2 + 2x - 4x - 8
f(x) = x^2 - 2x - 8
-14a-5=-12
+5 +5
-14a=-7
Divide -7 by -14a
a=2
Answer:
x=3
Step-by-step explanation:
3(x-2) + 6 = 3x - 2(3-x)
Using distributive property,
3x-6 + 6 = 3x - 6 + 2x
Subtract 3x from both the sides,
-6+6 = -6+2x
=> 2x-6 = 0
Add 6 on both the sides,
2x-6+6 = 0+6
2x = 6
Divide by 2 on both the sides,
x = 6/2 = 3
x = 3
I think its 0.6 because 2-5=3 and 2-(-3)=5 and 3÷5=0.6
Answer:
the answer will be 3.5 i think
