Select all the expressions that are solutions to 5 = 2/3x

A. 5 x 2/3

B. 5/2/3

C. 5 divided by 2/3

D. 15/2

E. 3/2 X 5

C. 5 divided by 2/3

D. 15/2

E. 3/2 X 5

Step-by-step explanation:

Given the expression

.-We can make x the subject of the formula and solve in many different ways:

#Multiply both sides by the reciprocal of 2/3:

#Multiply divide both sides by the factor of x:

Hence, the 3 possible solutions are  C, D and E:

answer: -0.5 would be the most likley outcome

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
