Answer: Hence, the value of expression is 30 when p = 8.
Step-by-step explanation:
Since we have given that

and we have p = 8.
So, we substitute the value of p in the above expression.
so, it becomes,

Hence, the value of expression is 30 when p = 8.
Answer:
100 - 12/n
Step-by-step explanation:
quotient means division so
12/n
and subtracted from means say x - 12/n so
100 - 12/n
If you're looking to evaluate it then it would be
4(25n - 3) / n

Answer: Angle A = 120° and angle C = 45°
Step-by-step explanation: The first thing to note at the back of our minds is that the sum of the interior angles of a triangle equals 180°. Given that the three angle are available, we can start by adding them all together. Hence,
{12x + 12} + 15 + {3x + 18} = 180
12x + 12 + 15 + 3x + 18 = 180
By collecting like terms, we arrive at,
12x + 3x + 12 + 15 + 18 = 180
15x + 45 = 180
Subtract 45 from both sides of the equation
15x = 135
Divide both sides of the equation by 15
x = 9
At this point, we can now substitute for the value of x = 9 in the expressions representing angles A and C.
Angle A = 12x + 12
= 12(9) + 12
= 108 + 12
= 120
Angle A = 120°
Angle C = 3x + 18
= 3(9) + 18
= 27 + 18
= 45
Angle C = 45°
