Answer:
x-intercepts: (2, 0) and (−5, 0)
y-intercept: (0, −10)
Step-by-step explanation:
y = x^2 + 3x − 10
y-intercept when x = 0 so y = -10, so y-intercept : (0, -10))
x-intercept when y = 0 so
x^2 + 3x − 10 = 0
(x +5)(x - 2) = 0
x + 5 = 0; x = -5
x - 2 = 0; x = 2
So x-intercepts: (-5, 0) and (2,0)

Answer:
30
Step-by-step explanation:
You set up the equation, 2x + x + 10=55 and then combine the 3x + 10=55. Minus 10 to both side and that gives you 3x = 45 and divide 3x to 45 and then x = 15 and plug x in 2x(Measure 2) and that equals 30
