Answer:
<em>2(x+3)</em>
Step-by-step explanation:
when adding, take the constant aside and group the similar variables together. In this case, the constant was 6 and the variable was x.
x+ x+ 6, can also be written as (2 times x) + 6.
= 2x + 6, which can also be written as 2(x+3)

40 - 12 = 28
28 / 40 = 0.7
0.7 * 100 = 70%
The percentage decrease is 70%.
Answer:
94°
Step-by-step explanation:
This is a quadrelateral, and so all the sides must equal 360.
Set the equation: F + 66 + 132 + 68 = 360
Isolate the variable F. First, simplify. Combine like terms: F + (266) = 360
Isolate the variable F. Subtract 266 from both sides:
F + 266 (-266) = 360 (-266)
F = 360 - 266
F = 94
94 is your answer.

Z^2 - 2z - 35 = 0
(z - 7)(z + 5) = 0
z - 7 = 0
z = 7
z + 5 = 0
z = -5
solution is : z = 7,-5
