Answer:
The value of π = 22/7 = 3.14
So here the Equation given we can examine those
1. 3π -1 > 9
=> (3 * 3.14 ) -1 > 9
=> 9.42 – 1 > 9
=> 8.42 > 9 , which is false
2. 7π > 21
=> (7 * 3.14) > 21
=> 21.98 > 21 , Which is true
3. π + 4 < 7
=> 3.14 + 4 <7
=> 7.14 <7 , Which is false
4. (12/ 4π) > 1
=> {12/ (4 * 3.14)} > 1
=> (12/12.56) > 1
=> 0.955 > 1 , Which is false

Step-by-step explanation:
Answer:
x^2+11x+30
Step-by-step explanation:
Answer:
y =52
Step-by-step explanation:
We know that the angles 4x and 5x make a straight line
4x+5x = 180
9x = 180
Divide by 9
9x/9 = 180/9
x = 20
The three angles of a triangle make 180
y + 48 +4x = 180
y + 48+4(20) =180
y + 48 +80 = 180
Combine like terms
y +128 = 180
Subtract 128 from each side
y + 128-128 = 180-128
y =52
