Answer:
Ok the answer is 3.6 because if 1 side is 1.8 feet then 2 sides would be 3.6 feet because I added 1.8 + 1.8 = 3.6 you can also just multiply 1.8 times 2.
Step-by-step explanation:
You just need to substitute x with 1/2
Your answer will then be 3(1/2) which is 3/2 or 1.5
The like terms are the variables which are being multiplied by different coefficients.
In this case, the like terms are:
3a, a
----------
Now, 3a + a = 4a
----------
Therefore:
3a + a + 5
= 4a + 5
A false hypothesis helps to understand what factors are not related to a certain outcome. This helps center experiments around hypotheses that are more relevant.
