R: -4,-3
S: -3,1
T: 1,-2
U: stays the same
((:
Make each into improper fraction
2 x 8 + 5. = 21 / 8
3(10) + 2 = 32/3
21/8(32/3) = ((21x32)/(8x3) reduce by 3/3
(7x32)/(8) reduce by 8/8
7x4 = 28
Nine year olds --> 36
ten year olds ----> 48
then simpifly this as if you would to a fraction
6/8 so the ratio would be 6:8
Answer:
The remaining area in the form of a polynomial function where 0 < x < 3.
Step-by-step explanation:
Breadth of rectangular piece of cardboard = 7 inches
Length of rectangular piece of cardboard = 20 inches
Area of cardboard =
Area of cardboard =
Area of cardboard =
Squares of length x inches on a side cut from each corner.
Length of square = x
Area of 1 square =
Area of 4 squares =
Area of remaining portion
So, the remaining area in the form of a polynomial function where 0 < x < 3.
