Answer/explanation
4(3x+5)=-4
You will distribute the four to every term in the parenthesis,
12x+20=-4
Then you will combine like terms
12x+20=-4
-20 -20
12x=-24
Then you will divide 12 to isolate x

Obviously, -24 cancels out and you would get x=-2
Answer:
- 2x² + 3x + 64
Step-by-step explanation:
3x - (2x-8)² Write the equation and distribute the exponent
3x - 2x² + 64 Write the equation in order of degree of exponents, or standard form
- 2x² + 3x + 64
Answer:
<h3>The value of

is

</h3><h3>The value of

is

</h3><h3>The partial derivative at s=-5 and t=10 is

is

</h3><h3>The partial derivative at s=-5 and t=10 is

</h3>
Step-by-step explanation:
Given that the Function point are 
,
and s = -5, t = 10
<h3>To find

and

using the appropriate Chain Rule :
</h3>
Substitute the values of x and y in the above equation we get


<h3>Now partially differentiating w with respect to s by using chain rule we have
</h3>



<h3>Therefore the value of

is

</h3>

<h3>Now partially differentiating w with respect to t by using chain rule we have
</h3>


<h3>Therefore the value of

is

</h3>
Now put s-5 and t=10 to evaluate each partial derivative at the given values of s and t :





<h3>Therefore the partial derivative at s=-5 and t=10 is

is

</h3>






<h3>Therefore the partial derivative at s=-5 and t=10 is

</h3>
