Answer:
x= −1
/2 or x=4
Step-by-step explanation:
This is ALGEBRA, equations, factoring and zero property. ok.. let's solve this step-by-step
2x^2−7x=4
<u>Step 1: Subtract 4 from both sides.
</u>
2x^2−7x<u>−4 </u>=4 <u>−4
</u>
2x^2−7x−4=0
<u>Step 2: Factor left side of equation.
</u>
(2x+1)(x−4)=0
<u>Step 3: Set factors equal to 0.
</u>
2x+1=0 or x−4=0
x= −1
/2 or x=4
(BTW, there are supposed to be two answers, it's factoring)
Sorry if the format is not clear, but I hope this helped (really feel you, algebra can be brain-striking)!! Please leave a comment, rating and/or mark as the brainliest-whichever you think I deserve! Thank You :)

Answer:
show me, I cant see anything
Don’t worry! I am happy to help you! Standard form is just the number alone. In this case, here are the numbers written out for you.
1. 53
2. 9,400
3. 707,000
4. 0.0026
5. 0.08651
6. 0.0000067
The next part here is scientific notation. The first number has to be greater than 1, but less than ten, and the number you multiply by is powers of 10, sometime positively and sometimes negatively. You can search up the powers of 10 chart to find more. Here they are written in scientific notation.
7. 5.61 * 10^3
8. 1.4 * 10^1
9. 5.64 * 10^7
10. 7.52 * 10^-1
11. 6.4 * 10^-3
12. 5.81 * 10^-4
For this next part, you have to get these answers and express it in scientific notation. Here are these answers with the work.
13. 69,000,000 + 212,000 = 69,212,000.
Scientific notation: 6.9212 * 10^7
14. 43,000 + 521,000 = 564,000
Scientific notation: 5.64 * 10^5
Negative reciprocal- Negative Reciprocal. Opposite Reciprocal. The result of taking the reciprocal of a number and then changing the sign.
parallel- In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.
