Answer:
Hence we prefer the distributive method when multiplying trinomial by a binomial.
Step-by-step explanation:
Explanation
- We have to explain when multiplying a trinomial by a binomial which method we prefer from the Distributive Property or the Vertical Method.
- We prefer the Distributive method because the method is the quickest than the vertical method methods as the vertical method has more steps than the distributive property also the vertical method is a bit complicated than the distributive method.

Answer:
He did not check for extraneous solutions.
Step-by-step explanation:
He solved the equation correctly and obtained solutions -2 and -5, but there is one final step he did not do.
Every time you square both sides of an equation to solve it, you must check for extraneous solutions. If he did, he would have eliminated x = -5.
Answer: He did not check for extraneous solutions.
Parallel never cross
perpendicular is a 90 degree angle
its neither if its not 90 degree or never crossing
Answer:
shs92800
Step-by-step explanation:
Let the money owned by the man be x.
Hence the man gave ⅝of his money to his son;
Meaning the son gets:
⅝ × x = ⅝x
¾ of the remaining to his daughter,
Meaning his daughter gets :
¾ ×(x-⅝x) = ¾×3/8 x = 9/32X
the remaining to his wife,
Meaning his wife gets:
x-(5/8x + 9/32x) = x - 29/32x = 3/32 x
But his wife's amount is Shs8700
Meaning 3/32x = Shs8700
x= Shs8700 × 32/3 = shs92800
