Answer:

Area = 3x^5+3x^4-3x^3-3x^2

Step-by-step explanation:

Area equals length times width

x(x+1) * 3x(x^2-1)

(x^2+x) * (3x^3-3x)

3x^2(x+1)(x^2-1)

3x^5+3x^4-3x^3-3x^2

(x+3)²(65)=x(6)<br>Solve using quadric formula​
Angelina_Jolie [31]

Step 1: Simplify both sides of the equation.

  • 65x²+390x+585=6x

Step 2: Subtract 6x from both sides.

  • 65x²+390x+585−6x=6x−6x
  • 65x²+384x+585=0

For this equation: a=65, b=384, c=585

  • 65x²+384x+585=0

Step 3: Use quadratic formula with a=65, b=384, c=585

  • x=−b±√b2−4ac/2a
  • x=−(384)±√(384)2−4(65)(585)/
  • 2(65)
  • x=−384±√−4644/130

Therefore, There are no real solutions.

Linear Functions <br> 7g+3g-10+3=43<br> Step by step solution? <br> Thankss!❤️
Ivahew [28]
7g + 3g - 10 + 3 = 43

(first combine likes terms)

10g - 7 = 43

(then add 7 to both sides)

10g - 7 = 43
        +7    +7

10g = 50

(then divide by 10 to get what g is equal to)

10g = 50
/10     /10

g = 5
