Step-by-step explanation:
x² + 4x - 32
= (x + 8)(x - 4).
Hence the x-intercepts are (-8, 0) and (4, 0). (B)

Answer:
a) 36°
b) 37°
Step-by-step explanation:
a) x=14 y=10
tan(0) = 10/14
0 = tan-1 (10/14)
0 = 36
b) x=17 y=13
tan(0) = 13/17
0 = tan-1 (13/17)
0 = 37
Two integers are 26 and 28
Step-by-step explanation:
- Step 1: Let the two consecutive positive integers be x and x + 2. Product = 728
x(x + 2) = 728
x² + 2x - 728 = 0
x = -2 ±√4 - 4 × 1 × -728/2 (using quadratic formula)
= -2 ±√4 + 2912/2
= -2 ±√2916/2 = -2 ± 54/2
= -56/2, 52/2
= -28, 26 (negative value is neglected)
∴ x = 26
x + 2 = 28
