aleksklad [387]

Answer:

12 $x^{2}$ + 29x - 14

Step-by-step explanation:

(3x+2)(4x-7)

Multiply out 3x first then 2

(3x * 4x) - (3x * -7) + (2 * 4x) + (2 * -7)

12 $x^{2}$ - (- 21x) + 8x + ( -14)

12 $x^{2}$ + 21x + 8x - 14 Combine like terms

12 $x^{2}$ + 29x - 14

PLEASE HELPPPPPP!!!!!!Solve this system of linear equations separate the x-and y-values with a comma

GenaCL600 [577]

Answer:

$x=-6,\\y=6$

Step-by-step explanation:

Rewrite the system of equations as:

$\begin{cases}-13x+2y=90\\-6x+2y=48\end{cases}$

Subtract the second equation from the first to isolate $x$ :

$-13x+2y-(-6x+2y)=42,\\-7x=42, \\\fbox{$x=-6$}$

Plug in $x=-6$ into any of the equations above and solve for $y$ :

$-6(-6)+2y=48,\\2y=12,\\\fbox{$y=6$}$

Verify that the solution pair $(-6, 6)$ works $\checkmark$

Therefore, the solution to this system of equations is:

$x=-6,\\y=6$
