Step-by-step explanation:
<h3>Given</h3>
- Side 1: 3x² - 2x - 1
- Side 2: 9x + 2x² - 3
- Perimeter: 5x³ + 4x² - x - 3
<h3>Part A</h3>
Sum of side lengths 1 and 2
- 3x² - 2x - 1 + 9x + 2x² - 3 =
- 5x² + 7x - 4
<h3>Part B</h3>
The perimeter is the sum of all three sides.
<u>The length of the third side is</u>
- P - (side 1 + side 2) =
- 5x³ + 4x² - x - 3 - (5x² + 7x - 4) =
- 5x³ + 4x² - x - 3 - 5x² - 7x + 4 =
- 5x³ - x² - 8x + 1
Part A - addition
Part B - subtraction
1/7 of 42 is smaller. 47/7= 6 < 18 = 36/2
Can u show me an example so I could do this foru
Answer:
Both processes are correct.
Step-by-step explanation:
Let the mile taken by Chase be 10miles .
He doubles it so it will be 20 and
20% of 20 will be 4
20-4 = 16km
Now Alex operations
(10/5 )*8 = 2*8= 16 km
In both cases the answer will be the same
1 mile = 1.60034 km
Now 10 miles = 16.00 34 km
which is the same as above.
Both the processes are correct.
