Answer:
d. 4x^2-20x-25
Step-by-step explanation:
So, we have to multiply (2x-5) by itself. That gives:
(2x-5) (2x-5) = 2x (2x-5) - 5 (2x-5) = 4x² - 10x -10x + 25
so, the correct answer is 4x² - 20x + 25
It's just important to multiply each component carefully by using the distributive property.
remove parenthesis : 2/3 - 5/6 + 9/4 - 3/5
add fractions based on lcm : 40/60 - 50/60 + 135/60 - 36/60
equal denominator so combine fractions : 40 - 50 + 135 - 36 / 60
add/subtract : 40 - 50 + 135 - 36 = 89
answer ; 89/60
18,-2,-14 just plug in for x
