7x-6=5(x+4)
7x-6=5x+20
-5x -5x
2x-6=20
+6 +6
2x=26
/2 /2
X=13
Answer:
It isn't very relaible, to insure that you get answers correct try to do them yourself or ask your teacher,
Step-by-step explanation:
Question one is y( Insert sign) -9
Explanation:
4²+4²≠8²
(4+4)²=8²
If you use PEMDAS you can find that 4²+4²=32 not 8² which equals 64
You can also find that (4+4)²=(8)²
Simple...
if f(x)= -5x-4 and g(x)=6x-7
And you want f(x)+g(x)
then just add.....f(x)+g(x)
-5x-4+6x-7
1x-11
This is the answer to f(x)+g(x)=1x-11
Thus, your answer.
