Answer:
7x³/10 - 7x² + 5x - 3/4
Step-by-step explanation:
The first step is to group the like terms and combine them. Once you do that, you should end up with 7x³/10 - 7x² + 5x + 1/4 - 1. When you combine -1 and 1/4, you should get -3/4. Afterwards, write the equation in standard form to get 7x³/10 - 7x² + 5x - 3/4. I hope this helps
Answer:
2.33 = ?
Step-by-step explanation:
We can use trig functions
tan theta = opposite/ adjacent
tan 25 = ? /5
Multiply each side by 5
5 tan 25 = ?
2.331538291 = ?
Round to the nearest hundredth
2.33 = ?
Simplify brackets
10x - 4 = 8x + 14
Add 4 to both sides
10x = 8x + 14 + 4
Simplify 8x + 14 + 4 to 8x + 18
10x = 8x + 18
Subtract 8x from both sides
10x - 8x = 18
Simplify 10x - 8x to 2x
2x = 18
Divide both sides by 2
x = 18/2
Simplify 18/2 to 9
<u>x = 9</u>
