Step-by-step explanation:
Area of the square = a²
= 20²
= 400cm²
Area of the circle = πr²
= 22/7 × 9²
= 22/7 × 81
= 254.57cm²
Area of the shaded region = Area of the square - Area of the circle
= 400cm² - 254.57cm²
= 145.43cm²
Because z is the unknown that we need to find, we treat t and a as constants (or numbers).
a(t+z)= 45z+67
⇒ at+ az= 45z+ 67 (distributive property)
⇒ at- 67= 45z- az
⇒ at- 67= z(45- a) (distributive property)
⇒ (at -67)/ (45- a)= z
Final answer: z= (at- 67)/ (45- a)

Step-by-step explanation:
Answer:
I believe the answer is C, the area of a circle, because pi is irrational, and anything multiplied by it will always result in an irrational number.
