Answer:
Step-by-step explanation:
To find the Scale factor we use this formula:
Scale factor / K = Dimension of the new shape ÷ Dimension of the original shape
Substitute any 2 corresponding sides into the formula:
I took 1 and 4:
K = 1 / 4
K = 0.25
I'm not sure which form the question is so I will leave it here.
Hope this helped. Brainliest please?
Answer:
x = 9
Step-by-step explanation:
take -6 to the other side so you add it to 30 = 36
equation is now 4x = 36
divide 4/4 and 36/4
x = 9
Let L be length and W be width
The perimeter of a rectangle is 2W+2L=36
Thus 2W=36-2L, W=18-L
Area of a rectangle is WL=80
Thus (18-L)(L)=80
18L-L^2=80
L^2-18L+80=0
(L-8)(L-10)
Thus L can either be 8 or 10.
Because WL=80
If L is 8, then W=10
If L is 10, then W=8
So either way, the notebook is 8 by 10
The 21 part repeats
it can be represented as 21/99
it's rational
