What are the roots of the polynomial equation x^4+x^3=4x^2+4x? Use a graphing calculator and a system of equations.
Yuliya22 [10]
Desmos graphing calculator will draw this graph for you.

draw 2 curves

y = x^4 + x^3 
and
y = 4x^2 + 4x

The roots are the points where the 2 curves intersect.

You can see by simple substitution that one root is zero.

x^4 + x^3 - 4x^2 - 4x = 0

f(2)  = 16 + 8 - 4(4) - 4(2)  = 0   so 2 is another root

f(-2) = 16 - 8 - 16 + 8 = 0  so  -2 is another root

f(-1) = 1 - 1  - 4 + 4 = 0 so -1 is the other root

The answer is A

The measures of two sides of a triangle are given. If P is the perimeter, and P = 10x + 5y, find the measure of the third side.
katen-ka-za [31]

The measure of the third side is  2x + 2y

A triangle can be described as a polygon with three sides. The sum of the angle in a triangle is 180 degrees.

<u><em>Types of triangles are: </em></u>

  1. right angled triangle
  2. scalene triangle
  3. equilateral triangle
  4. isosceles triangle

The perimeter of a triangle is the sum of its three sides

(3x + 4y) + (5x - y) + s = 10x + 5y

Add similar terms

8x +3y + s = 10x + 5y

Make s the subject of the formula

s = 2x + 2y

What is the solution to the equation below? Round your answer to two decimal places. 4*e^x=12.76
sveta [45]

Answer:

x=1.16

Step-by-step explanation:

we have

4(e^x)=12.76

Solve for x

That means ---> Isolate the variable x

Divide by 4 both sides

(e^x)=3.19

Apply ln both sides

ln[(e^x)]=ln(3.19)

Apply property of logarithms (power rule) left side

(x)ln(e)=ln(3.19)

Remember that

ln(e)=1

x=ln(3.19)

x=1.16
