And the other two options are A:108 and B: the equation has two real solutions. Please help! thank u:)

The discriminant is zero which means there is 1 repeated real solution

Step-by-step explanation:

9x^2 -12x +4 = 0

This is in the form

ax^2 +bx +c

a = 9 b=-12 c=4

The discriminant is

b^2 -4ac

(-12)^2 - 4(9)(4)

144 -144

0

The discriminant is zero which means there is 1 repeated real solution

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
