It's C. move all terms to the left side and set equal to zero. then set each factor equal to zero.
The number of bacteria in a culture is increasing according to the law of exponential growth. There are 125 bacteria in the culture after 2 hours and 350 bacteria after 4 hours.
Explanation:
Sum of all angles= 180 degrees
So,
3x + 75= 180
3x= 180 - 75
3x= 105
x= 105/3
x= 35
Answer= 35 degrees
25-4x=16-4x
25-4x+4x=16-4x+4x
25=16

Answer:
- angle at A: 51°
- base angles: 64.5°
Step-by-step explanation:
The measure of the inscribed angle BAC is half the measure of the intercepted arc BC, so is 102°/2 = 51°.
The base angles at B and C are the complement of half this value, or ...
90° -(51°/2) = 64.5°
The angle measures in the triangle are ...
∠A = 51°
∠B = ∠C = 64.5°
