Answer:
One rational solution
Step-by-step explanation:
proof
5x2 - 2x - 3=0, the sum of coefficients is 5-2-3=0, so the equation has exactly two solutions, x=1, and x = -3/5 this last is the one rational solution
Let n = number
"3 times the sum of a number and 7" translates to 3(n + 7)
"2 less than five times the number" translates to 5n - 2
The word "is" becomes the equals sign.
3(n + 7) = 5n - 2
I think you already asked this one.
195 sq meters. Area of triangle is......
Base times Height divided by Two
25 = 5.2 + 8 + x
5.2 + 8 = 13.2
25 = 13.2 + x
25 - 13.2 = 11.8
11.8 = x
The unknown side is 11.8 ft.
