Answer:
−25x+54−32rx+64r−x^2
Step-by-step explanation:
(−28−32r−x+1)(x−2)
Add −28 and 1 to get −27.
(−27−32r−x)(x−2)
Apply the distributive property by multiplying each term of −27−32r−x by each term of x−2.
−27x+54−32rx+64r−x^2+2x
Combine −27x and 2x to get −25x.
−25x+54−32rx+64r−x^2
Answer:
3:2
Step-by-step explanation:
Reduce both numbers to their smallest form and put into ratio format
According to the rules of math: multiplying comes before substraction(minus) so first multiply...
90×35×12455680= 39235392000
then minus 80 from the answer you got from multiplying.
39235392000-80= 39235391920
