Noah started with a number, x.
Four times the number x is 4x
The difference of four times the number and three is 4x - 3
The difference of four times the number and three cubed is
Thus, the expression representing Noah’s new number is
99+3b
The original equation would be 3(33+b), but simplifying it would get 99+3b.
8
Let's call the missing side as xBase on the pythagorean theorem, we have : 17² - 15² = x²289 - 225 = x²x² = 64So, x equals 8.Hope it helps
2x² +7x - 4
(2x-1)(x+4)
2x² + 8x - x - 4
simplify:
