Answer:
false
Step-by-step explanation:
This is a solution to the first equation because
5+-9=-4
-4=-4
however, if you plug it into the next equation, it becomes false.
5--9=4
14=4
this does not make sense.
(9x^2)-12x+4
This is the same as (3x-2)(3x-2), so use any method of multiplying, however I will show the FOIL method of multiplying polynomials.
F (First numbers in each polynomial): 3x*3x = 9x^2
O (Outside numbers): 3x*-2 = -6x
I (Inside numbers): -2*3x = -6x
L (Last numbers in each polynomial): -2*-2 = 4
Now just combine like terms to add these together and get (9x^2)-12x+4.

Answer:
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32
Step-by-step explanation:
Let Cost of one bush = x
Cost of one bonsai tree = y
From the expression: A company paid $ 391 for 15 bushes and 8 bonsai trees
We made equation:
and From the expression: They had to purchase 9 more bushes and 5 more bonsai trees for $ 241 , we made equation:
Solving both equations simultaneously we can find value of x and y
Let:
We will use elimination method to solve these equations.
Multiply eq(1) by 5 and eq(2) by 8 and subtract
So, value of x=9
Now finding value of y by putting value of x in equation 1
So, value of y=32
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32
The answer that I got:
t>4
