Answer:
Step-by-step explanation:
Let's check all the monomials

Here 6 is not square digit, hence this monomial is not a perfect square.

Here 9 is a square digit and the power of x i.e. 8 is multiple of 2 .
Hence, this monomial is a perfect square.

Here 16 is a square digit but the power of x i.e.9 is not multiple of 2 .
Hence, this monomial is not a perfect square.

Here 25 is a square digit and the power of x i.e. 12 is multiple of 2 .
Hence, this monomial is a perfect square.

Here 36 is a square digit and the power of x i.e.16 is multiple of 2 .
Hence, this monomial is a perfect square.

3/4x - 5y = 7<br> X = -4y + 12<br><br> solve by substitution ! show work pls !!
tamaranim1 [39]
When using substitution, we are imputing an equation in place of a variable to eliminate one of the variables in the equation so that we can solve for the remaining variable.

For this example, we will be plugging in (-4y+12) wherever "x" is in the other equation.

3/4 x -5y = 7
3/4(-4y+12) -5y =7
((3/4)(-4y))+((3/4)12)-5y=7
-3y+9-5y=7
-8y= -2
y=(1/4)


Now find "x" by plugging in the y-value.
x=(-4*(1/4))+12
x= -1 +12
x=11
