Answer:
1.203125
Step-by-step explanation:
431 ≈ 400
115 ≈ 100
400 - 100 = 300

Answer:
1. 2m+2n+7
2. 3m-2
3.-2m+2-2n
Explanation:
To find the sum of given polynomials (m+n+3) +(m+n+4)
Firstly, open the parenthesis we will get m+n+3+m+n+4
After simplification we will get 2m+2n+7
To find the difference of given polynomials (10m-6)-(7m-4)
Firstly, open the parenthesis we will get 10m-6-7m+4
After simplification we will get 3m-2
Again to find the difference of the polynomials (4m-5)-(6m-7+2n)
Firstly, open the parenthesis we will get 4m-5-6m+7-2n
After simplification we will get -2m+2-2n
Slope intercept form
y = mx+b
y = -7x + 9
m = -7
