4x = 3y + 9, y = x + 1. 4x = 3(x + 1) + 9 4x = 3x + 3 + 9 x = 12. y = 13.
(2x - 3)(4x + 9)(2x + 3) = (2x - 3)(2x + 3)(4x + 9) = [(2x)^2 - (3^2)](4x + 9) = (4x^2 - 9)(4x + 9) = (4x^2)(4x) + (4x^2)(9) - (9)(4x) - (9)(9) = 16x^3 + 36 x^2 - 36x - 81
4x+5 = -9 4x = -9-5 4x = -14 x = -3.5
4x(7+9)= 28+36=64.

4x = 3y + 9, y = x + 1. 4x = 3(x + 1) + 9 4x = 3x + 3 + 9 x = 12. y = 13.
5x - 9 = 4x 5x - 4x - 9 = 4x - 4x x - 9 = 0 x - 9 + 9 = 0 + 9 x = 9
(2x - 3)(4x + 9)(2x + 3) = (2x - 3)(2x + 3)(4x + 9) = [(2x)^2 - (3^2)](4x + 9) = (4x^2 - 9)(4x + 9) = (4x^2)(4x) + (4x^2)(9) - (9)(4x) - (9)(9) = 16x^3 + 36 x^2 - 36x - 81
4x+5 = -9 4x = -9-5 4x = -14 x = -3.5
4x - 9 = 35 4x = 35 + 9 4x = 44 4x/4 = 44/4 x=11
4x(7+9)= 28+36=64.
She isn't. 4x squared is 4 times (x squared). That is, 4 times (3 squared) = 4 times 9. If you want it to be the square of 4x (which would be the square of 4 times 3, ie, 12), you have to write it as (4x)squared.
4x+9=25 4x+9=25-9 4x/4=1 16/4=4 4x+9=26 4(4)+9=25 16+9=25 The answer is 4
4x × 4x = (4x)² = 16x²
4X - 1 = 9 Is an equation. 4X - 1 = 9 4X = 10 X = 5/2 =====
Let's represent the unknown number as "x." The quotient of -36 and 9 can be expressed as -36/9. The equation can be written as (-36/9) > 4x + 8. Simplifying, we get -4 > 4x + 8. By further simplifying, we find -12 > 4x, which can be written as x < -3.
