Answer:

Five more than the square of a number= 5 + x²

Five more than twice a number = 5 + 2x

Five less than the product of 3 and a number = 3x - 5

Five less the product of 3 and a number = 5 -3x

Twice the sum of a number and 5 = 2(x + 5)

The sum of twice a number and 5 = 2x + 5

The product of a cube of a number and 5= 5x³

The cube of the product of 5 and a number= (5x)³

Answer:

(5x)³=

(5x) ao cubo  

5.5.5=125X³

2(x+5)= 2x+10

             2x=10

              x=10/2

                X=5

2x+5= 2x - 5 = 0  

2x = 0 + 5  

2x = 5  

x = 5/2

3x-5= 3x= +5

           X= 5/3 or X= 1,6

5+2x= 2x=-5

            X= -5/2

5+x²= x²+5  a=1 b= 5 c=0

5²-4.1.0 (corta,pois -4.1.0=0)

=25  

x= -b +/- raíz de bhaskara/ 2.a

x=-5 +/- 5/2

x'= 0/2=0

x"=  -10/2= -5

5-3x= 3x=-5

          X= -5/3

5x³ = 0   a=5 b= 0 c=0

0²-4.5.0

= 0 (duas raízes reais e iguais)

x'= 0

x"= 0
