Answer:
9m^2 + 18m + 9
Step-by-step explanation:
(3m + 3)2
Square ;
(a + b)^2 = a2 + b2 + 2ab
(3m + 3)2
= (3m)^2 + (3)^2 + 2 (3m)(3)
= 9m^2 + 9 + 18m
= 9m^2 + 18m + 9
Answer:
y = -1/2x + 2.5
Step-by-step explanation:
- slope of a perpendicular line is the negative reciprocal of the original slope (2 in this case) so y = -1/2 x + c
- to find c we substitute the values from the given point into the equation
(0) = -1/2*(5) + c
- rearrange and calculate and you'll get c = 5/2 or 2.5
- replace the value of c and now you've got y = -1/2x + 2.5
2x + 2x + x = 180°
5x = 180°
x = 36° (C)
