Hey is it meant to be just a black screen kinda confused
Answer:
150.8
Let me know if you need an explanation.
Answer:
A is false it said it could be greater than 35 or equal to and 100 x 5 = 500 + 1 = 501 therefore a is false
B is false 6.8 could be possible and it could be a decimal it can't only be a whole number
C is false 6 4/5 is a solution so c is false
D is I'm not sure, I think infinite except for 7 and below so maybe true
E is false because any number greater than 7 that are multiplied to 5 can be as long as its greater than or equal to 35
Ok this is what I think. Id rather wait for more answers to be sure thank you.

Answer:
x² + 4x + 20 = 12x - 5
x² + 4x - 12x + 20 + 5 = 0
x² - 8x + 25 = 0
Δ = √b² - 4ac
= √(-8)² - 4×1×25
= √64-100
= √(-36)
x ∉ R
