What are the solutions 2x^2 +7x=4
elena55 [62]
So your equation is 2x^{2} +7x = 4. You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now 4x + 7x = 4.
You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's 11x = 4 right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be

0.36.

I hope I helped!

Answer:

B

Step-by-step explanation:

tan22° = \frac{opposite}{adjacent} = \frac{203}{x}

Multiply both sides by x

x × tan22° = 203 ( divide both sides by tan22° )

x = \frac{203}{tan22} ≈ 502.5 m → B
