To simplify the expression (3m - 10 \cdot 2(4m - 5)), first calculate (10 \cdot 2 = 20). Then, distribute (20) across (4m - 5): (20(4m) - 20(5) = 80m - 100). Now, combine this with (3m): (3m - (80m - 100) = 3m - 80m + 100 = -77m + 100). Thus, the simplified expression is (-77m + 100).
4m + 3m = 180 7m = 180 m = 25 5/7
2(3m-5)
It simplifies to -10-4m
Every one of them could be a side of a rectangle. It is not possible to give an answer in respect of an unspecified rectangular object. however, i feel the question is incorrect as it should be sides of the triangle and according to it 3rd is the answer as 3+5<9 :)
3m + 7 = 5 Subtract 7 from both sides: 3m = -2 Divide both sides by 3: m = -2/3
The value of m in the equation: 4m-5 = 3m +7 is 12.
It is: 4m+5
4m + 3m = 180 7m = 180 m = 25 5/7
5*4*3 60?

(3m + 2)(2m - 5)
3m + 15 = 45 3m = 30 m = 10
3m+2=17 First, subtract 2 to get m on one side. 3m+2-2=17-2 3m=15 Divide by 3 to get m by itself. 3m/3=15/3 m=5 m equals 5.
3m + 7 = 5 Subtract 7 from both sides: 3m = -2 Divide both sides by 3: m = -2/3
m2-3m=-1 => m2-3m+1=0 Delta = (-3)2 - 4 * 1 * 1 = 5 m = (3 + sqrt(5)) / 2 or m = (3 - sqrt(5)) / 2
