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!

What Are the values of x and y?

dem82 [27]

Answer:

y = 72.5

x = 35.

Step-by-step explanation:

First Off, Let's Divide the question.

Let's Find the variable y : 

there are 2 y(s), so it is 2y.

equation: 2y +35 =180.

I put 180 because A straight Line is always 180.

2y+35=180

1. Subtract both sides.

2y = 145

y = 72.5

Next,Find x 

So y + y + x = 180.

We already know y, which is 72.5

72.5 +72.5 + x = 180

72.5 +72.5

x + 145 = 180

x = 35.

Hope This Helps!
