<u>Answer:</u> The value of x will be 2.
<u>Step-by-step explanation:</u>
To calculate the value of 'x' or solve for x, we need to isolate x from 8.
In the equation, 8 is in addition with 'x' so for isolating it, we need to apply the reverse operation of addition.
Reverse operation of addition is subtraction.
We need to subtract 8 from both sides of the equation, we get:

By doing this, we get the value of 'x' as 2.
Error done by Alice was that she added 8 and it did not led to the isolation of 'x'.
Answer:
the answer is w
^2
+
9
w
+
20
Step-by-step explanation:
(5+W)(W+4)
multiply w by w and get w^2 and the 5+w=5w and 4+w=4w and get 9w and then multiply 5*4=20 and then put all together in order of greatest exponent to smallest
w^2+9w+20
hope this helps :) plz give brainiest
