In this case this "of" means we will multiply the two fractions "4/5 × 3/4" exists 3/5.
<h3>What are fractions?</h3>
That operation exists utilized to 'simplify' a fraction (reduce it to lower terms).
When there exists no number that goes into both the top and bottom numbers, then the fraction is in simplest form (lowest terms).
We are looking for 4/5 of 3/4. In this case this "of" means we will multiply the two fractions. To multiply fractions, we multiply
top × top and bottom × bottom
4/5 × 3/4 exists 4 × 3 on top and 5 × 4 on the bottom.
= (4 × 3)/(5 × 4)
= 12 / 20
= 3 / 5
Therefore, the correct answer is 3/5.

45=k√5
times both sides by √5
45√5=5k
divide both sides by 5
9√5=k
Answer:
Step-by-step explanation:
2x² + 3x - 20 = 0
a = 2 ; b = 3 ; c = -20
[ -b ± √(b² - 4ac) ] /2a = [-3±√(3²-4*2*-20]/2*2
= [-3±√(9+160)]/4
= [-3±√169 ]/4
= [-3± 13]/4
=
