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
Jesos it’s all pixelated I can’t see anything on mi phone br
So normally it is
if 8x is to 6y, then how many x is to 42y?
it could be
if 8x:6y then how many x:42y or
if 8x:6y then how many y:42 x
I will solve for both
if it is
x:42y go to AAAAAAAA
if it is
y:42x then go to BBBBBBBBBB
AAAAAAAA
how many concerts are equal to 42 symponies
arrange in concerts to symponies format
8:6=x:42
fractionify
8/6=x/42
multiply boht sides by 42
336/6=x
56=x
56 concerts equals 42 symponies
BBBBBBBBBB
how many symponies are equal to 42 concerts
areange in symponies:concerts
6:8=x/42
fractionify
6/8=x/42
multiply boht sides by 42
252/8=x
31.5=x
31.5 symponies to 42 concerts
so it could be
56 concerts to 42 symponies
or
31.5 symonies to 42 concerts
