Answer: x = ±√145

Step-by-step explanation:

√(17 + x) × √(17 - x) = 12

√(17 + x) (17 - x) = 12

Squaring both sides,

(√(17 + x) (17 - x))^2 = 12^2

(17 + x) (17 - x) = 144

17(17 - x) + x(17 - x) = 144

289 - 17x + 17x - x^2 = 144

x^2 = 289 - 144

x^2 = 145

x = ±√145

Answer: 1/3 (p+45)

Step-by-step explanation:

when you multiply p by 1/3, a fraction, it kinda divides. the parentheses come first so that’s p+45=45p. 45px1/3 (or divided by three), is 15p

Y = 4x - 3
y = mx + b
m = 4
b = -3
y intercept = (0,3)
(x,y) = (0,3)
(x,y) = (1,1) - substitute in ori equation
