Solve for x in the equation 2 x squared + 3 x minus 7 = x squared + 5 x + 39.
Nastasia [14]

Answer:

\implies x=1\pm \sqrt{47}

Step-by-step explanation:

We want to solve for x in 2x^2+3x-7=x^2+5x+39

You need to group and combine like terms and write in standard form:

2x^2-x^2+3x-5x-7-39=0

\imples x^2-2x-46=0

By comparing to ax^2+bx+c=0, we a=1,b=-2 and c=-46

The solution can be obtained using the quadratic formula.

x=\frac{-b\pm \sqrt{b^2-4ac} }{2a}

We substitute the coefficients to get:

x=\frac{--2\pm \sqrt{(-2)^2-4*1*-46} }{2*1}

x=\frac{2\pm \sqrt{4+4*46} }{2}

x=\frac{2\pm \sqrt{4*47} }{2}

x=\frac{2\pm2\sqrt{47} }{2}

\implies x=1\pm \sqrt{47}

The last choice is correct

The tallest tree in the world is 379 feet tall. How tall will each of the trees be in the year 2030 if their models continue? Is
tresset_1 [31]

Models are patterns that are used to predict measurements and populations

<h3>How to model the tree</h3>

The question is incomplete, as the model and the dataset to model that growth of the tree are not given.

So, I will give a general explanation

If the model of the tree follows a linear model (e.g y = 2x + 3), then the model is not reasonable.

This is so because, population and growth cannot be measured by a linear model

However, if the growth of the trees follow an exponential model (e.g y = 2(3)^x), then the model is reasonable
