Answer:
n=9
Step-by-step explanation:
You use reverse PEMDAS.
First you would divide by 3 on both sides. This should give you:
n²=81
Then you would find . Which is 9.
Use the distributive property and then combine like terms to simplify this expression: 9x + 5(x + 4)

Answer:
is the slope intercept form for 16x+9y=40
Step-by-step explanation:
Here, the given equation is 16 x + 9 y = 40
Now, the slope intercept form of an equation is y = mx + c,
here m = slope of the equation, b = y - intercept
So, now 16x + 9y = 40 on simplification gives
9y = 40 - 16x
or
or, is the slope intercept form of the given equation.
Here, m = (-16/9) and y- intercept = 40/9
