Factorized form:
(7m - 2u)(7a - 10m)
The answer is 8 + 2m cubed. hope this helped.
For x=5 y=4 so we can calculate the slope m=(y1-y)/(x1-x)=(5-0)/(4-0)=5/4
then use (y-y1)=m(x-x1) and you get
y=(5/4)x-5
I dont know exactly your answer but ill tell you how to solve add all your numbers together and then divide it by 45 (the number of numbers u have)
Answer:
Width =9 cm
Length =6 cm
Step-by-step explanation:
Let x be width, then length is x − 3
Let area be E. Then we have: E = x ⋅ (x −3)
54= x^2-3x
x^2-3x-54=0
We then do the Discriminant of the equation:
D=9+216
D=225
X1=3+15 over 2. which is 9
X2= 3-15. over 2. which is -6 Which is declined, since we can't have negative width and length.
Therefore x is 9. So width
So width = x = 9cm and length is x-3 = 9-3cm=6 cm
