Answer:

x + 2(-4) = 10

Step-by-step explanation:

Substituting -4 for y in the second equation results in x + 2(-4) = 10. This simplifies to x - 8 = 10 and then x = 18.

Please, when the problem statement includes possible answer choices, share them.

Hi,
Let assume a the width and b the length of the rectangular area.
$\left \{ {{2a+b=116} \atop {a*b=1682}} \right. \\\\

 \left \{ {{b=116-2a} \atop {a*(116-2a)=1682}} \right. \\\\

 \left \{ {{b=116-2a} \atop {a^2-58a+841=0}} \right. \\\\

 \left \{ {{b=116-2a} \atop {(a-29)^2=0}} \right. \\\\

 \left \{ {{a=29} \atop {b=116-2*29}} \right. \\\\

 \left \{ {{a=29} \atop {b=58}} \right. \\\\

If f(x) = x-6 and g(x)= 1/2x (x+3), find g(x) * f(x)

sertanlavr [38]

Answer:

Final answer is $g\left(x\right)\cdot f\left(x\right)=\frac{\left(x-6\right)}{2x\left(x+3\right)}$ .

Step-by-step explanation:

given functions are $f(x)=x-6$ and $g\left(x\right)=\frac{1}{2x\left(x+3\right)}$ .

Now we need to find about what is the value of $g\left(x\right)*f\left(x\right)$ .

$g\left(x\right)*f\left(x\right)$ simply means we need to multiply the value of $f(x)=x-6$ and $g\left(x\right)=\frac{1}{2x\left(x+3\right)}$ .

$g\left(x\right)\cdot f\left(x\right)=\frac{1}{2x\left(x+3\right)}\cdot\left(x-6\right)$

$g\left(x\right)\cdot f\left(x\right)=\frac{\left(x-6\right)}{2x\left(x+3\right)}$

Hence final answer is $g\left(x\right)\cdot f\left(x\right)=\frac{\left(x-6\right)}{2x\left(x+3\right)}$ .
