Answer:
No I don't agree with their solution; both their answers are wrong.
Correct answer is
.
Step-by-step explanation:
Given:

Now given:
According to Mai
and According to Tyler 
Now we need to find which of them is correct.
So we will solve the given equation we get;

Subtracting both side by 1 we get;

Now Multiplying both side
we get;

Hence both of them are incorrect, correct answer is
.
2x^2-12x+18 this is the answer from my friend
Answer:
6.67 yards
Step-by-step explanation:
20 feet. The builder asks him to give the measurements in yards. What will be the length in yards?
Please note that:
1 foot = 0.333 yard
20 feet = x yards
Cross Multiply
1 foot × x yards = 20 feet × 0.333 yards
x yards = 20 feet × 0.333 yards/1 foot
x yards = 6.66667 yards
Approximately = 6.67 yards
Therefore, the measurements in yards is 6.67 yards.
1/20 is the fraction that you'll have left
The last terms must multiply to the last terms (confusing)
example
if ax^3+bx^2+c+d=(ex+f)(gx+h)(jx+k) then
d=fhk
so
70 is last term
we got 2 and 5
2*5*?=70
10*?=70
divide by 10
?=7
the missing number is 7
