Answer:
2 x^2 - 3 x + 6
Step-by-step explanation:
Simplify the following:
-(3 x^2 + 4 x - 17) + 5 x^2 + x - 11
-(3 x^2 + 4 x - 17) = -3 x^2 - 4 x + 17:
-3 x^2 - 4 x + 17 + 5 x^2 + x - 11
Grouping like terms, 5 x^2 - 3 x^2 + x - 4 x - 11 + 17 = (5 x^2 - 3 x^2) + (x - 4 x) + (-11 + 17):
(5 x^2 - 3 x^2) + (x - 4 x) + (-11 + 17)
5 x^2 - 3 x^2 = 2 x^2:
2 x^2 + (x - 4 x) + (-11 + 17)
x - 4 x = -3 x:
2 x^2 + -3 x + (-11 + 17)
17 - 11 = 6:
Answer: 2 x^2 - 3 x + 6
Scale is 1:1000
Thus 9.3cm the actual is 9.3×1000= 9300cm = 93m
One centimeter equals 10 millimeters.
Answer:
53°
Step-by-step explanation:
With reference angle A
perpendicular (p) = 9.6
base (b) = 7.2
Now
tan A = p / b
tan A = 9.6 / 7.2
A = tan^ - 1 ( 9.6 / 7.2)
A = 53°
