3x^2 + 21x
Is the answer without a doubt.
Answer:
72 degrees.
Step-by-step explanation:
If the angle is x degrees its complement is 90-x degrees and it's supplement is 180-x degrees.
4(90-x) = 2/3(180 - x)
360 - 4x = 120 - 2/3 x
360 - 120 = -2/3 x + 4x
240 = -2/3 + 12/3 x
240 = 10/3 x
x = 240 * 3/10
x = 72 degrees.
The answer would be A because 3.90 x 3.5 is equal to 13.65
(x) = 95x + 25 is correct, since the $25 cost is fixed, but the $95 cost increases as x increases.
Answer:
2.35×10^9
2350 million = 2,350,000,000
1 million= 1,000,000
