The result of multiplying the polynomials is (2x + 3) (-x + 2y - 4) = -2x² + 4xy - 11x + 6y - 12
<h3>How to multiply the
polynomials?</h3>
The polynomial expression is given as
(2x + 3) (-x + 2y - 4)
Expand the brackets in the above polynomial expression
So, we have
(2x + 3) (-x + 2y - 4) = 2x * (-x + 2y - 4) + 3 * (-x + 2y - 4)
Open the brackets in the above polynomial expression
So, we have
(2x + 3) (-x + 2y - 4) = -2x² + 4xy - 8x + -3x + 6y - 12
Evaluate the like terms in the above polynomial expression
So, we have
(2x + 3) (-x + 2y - 4) = -2x² + 4xy - 11x + 6y - 12
Hence, the solution is -2x² + 4xy - 11x + 6y - 12

There correct answer to that question is 22.45
Hey there!!
Take the cinnamon tea as ' x ' and spice tea as ' y '
10 x + 2y = 19 -------------- ( 1 )
16x + 10y = 44 --------------- ( 2 )
Multiply the first equation by 5
50x + 10y = 95
16x + 10y = 44
Subtract the second equation from the first
34x = 51
x = 51 / 34
x = $1.5
Substitute this in any other equation
15 + 2y = 19
2y = 4
y = 2
Cinnamon = $1.5
Spice tea = $2
Hope helps!
Answer:
x=4
Step-by-step explanation:
-3x+4x=2*4-x
x=8-x
8=x+x
8=2x
x=8/2
x=4
I'd go with the subtraction property of equality:
a = b + c precisely when a - b = c
