2√20=2((√4)(√5)=2((2)(√5)=4√5
now we have
4√5-3√5=1√5=√5
So percent means parts ouf of 100
x%=x/100
so marked up form original to new price
100%=original
marku=35%
new price=100+35=135%
new price=59.40
so therefor
59.40=135/100 of original price
'of' means mutiply
replace 'origional price' with x
59.40=135/100 times x
simplify 135/100 to 27/20
59.40=27/20 times x
mutiply both sides by 20/27 to clear fraction
1188/27=x
44=x
original price=$44

Answer:
4x^3 - 15x^2 - 10x + 24
Step-by-step explanation:
FOIL (x-4)(4x^2+x-6)
= x(4x^2+x-6) -4(4x^2+x-6)
= 4x^3+x^2-6x-16x^2-4x+24
=4x^3-15x^2-10x+24
