6x+4y=20 I’m here to help buddy and give me that Brainly answer bro
So firstly, you'll want to multiply 1/2 and (n-4) and also reverse the signs in (2n+3), and your equation will look like this:

Next, you'll want to combine like terms, and your equation will look like this:

Next, subtract 1/2n on each side. Your equation will look like this:

Lastly, you'll divide 1.5 on each side, and your answer should be
Step-by-step explanation:
step 1. a polynomial must have whole non negative exponents
step 2. A, B, D have negative exponents
step 3. C is a polynomial.
Answer:
The slope will be:
slope = 0.3
Step-by-step explanation:
As we know that the slope of a certain line is basically the measure of its steepness.
Mathematically, the slope can be calculated as 'rise over run'.
In other words, the 'rise' is 'change in y', and 'run' is 'change in x'.
Given
The roof of the school has a rise = 3.6 meters = rise = change in y
The roof of the school has a run = 12 meters = run = change in x
So the slope will be:
slope = rise ÷ run
= 3.6 ÷ 12
= 0.3 ∵( 3.6 ÷ 12 = 0.3)
Therefore, the slope will be:
slope = 0.3
