Answer:
q = ± 
Step-by-step explanation:
We are to solve for q in:
16pq² = 25
q² = 
= ±
= ± 
For this case we have the following definition:
A real number can be a rational number or an irrational number.
The rational numbers are those that can be expressed as the quotient of two integers, such as 3/4, -21/3, 5, 0, 1/2, while the irrational numbers are all the others.
Between 0.1 and 0.11 we have:
Rational number: 105/1000 = 0.105
Irrational number: 01057685429832687
The coefficients are -7, 8, -3, 1, and -9
The area of the trapezoid is 45 cm²
