What is the GCD of 5x and 40x?
5x
Factor 25x2 plus 40x plus 16?
25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
3 over 5x plus 22 equals 28?
3/5x + 22 = 28 To solve this: Subtract 22 from both sides: 3/5x = 6 Multiply by 5x: 3 = 6*5x Divide by 6: 3/6 = 5x Divide by 5: (3/6)/5 = x Work it out: 3/6 = 0.5 0.5/5 = 0.1 x = 0.1
15x2 plus 58x plus 48?
15x2 + 58x + 48= 15x2 + 18x + 40x + 48= 3x(5x + 6) + 8(5x + 6)= (3x + 8)(5x + 6)
When 10 is added to the product of 5 and a number the result is 50 what is the number?
10 + 5x = 505x = 40x = 8
What is the GCD of 5x and 40x?

How do you solve 8 parentheses 1 plus 5x parentheses plus 5 equals 13 plus 5x?
8(1+5x) +5 = 13+5x => 8+40x + 5 = 13 +5x => 13+40x = 13+5x => 13-13+40x = 13-13+5x => 40x = 5x => 40x - 5x = 0 => 35x = 0 => 35x/35 = 0/35 => x = 0
What are the factors of 25x2 plus 40x plus 16?
The factorization of 25x2 + 40x + 16 is (5x+4)(5x+4).
Factor 25x2 plus 40x plus 16?
25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
