Answer:
5 yards
Step-by-step explanation:
5 pieces x 1 yard each =5
For x=3
3 + 3·3 + 5 = 17 ≠ 33
For x=5
5 +3·5 + 5 = 25 ≠ 33
For x=7
7 + 3·7 + 5 = 33 . . . . . this is the solution
For x=9
9 + 3·9 + 5 = 41 ≠ 33

Answer:
105 sweets
Step-by-step explanation:
There are 4 + 1 + 2 = 7 parts in total
Stephen gets 4 parts (or 4x)
Jim gets gets 2 parts (or 2x)
Given,
Stephen gets 30 more than Jim, we can write:
Stephen = Jim + 30
or
4x = 2x + 30
We can solve for "x":

There are 7 parts of sweets altogether (or 7x), we know x so:
There are:
7 * 15 = <u>105 sweets</u> altogether
Answer:
4-(x-3)²
Step-by-step explanation:
5-6x-x²
=4-x²-6x+9
=4-(x-3)²
