Answer: Option B
B. 
Step-by-step explanation:
We have the following equations:
(1)
(2)
Let us call "a" the coefficient of the variable x in the first equation and call "b" the coefficient of the variable x in the second equation.
Then we must multiply the number "a" by a value z such that when adding
the result is zero.

So

We solve the equation for z


The first equation must be multiplied by a value of 
Answer:
201.06 square feet
Step-by-step explanation:
area of a circle is given by πr², where π = 3.1416
A = 3.1416 * 8²
A = 3.1416 * 64 = 201.0624 square feet
A = 201.06 square feet

Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
(2y⁴)³
Using the rules of indices
That's
<h3>

</h3>
So for the above expression we have
<h3>

</h3>
Simplify
We have the final answer as
<h2>8.y¹²</h2>
Hope this helps you
Answer:
Area = Length × width
16 = (3x +2 ) × ( x)
16 = 3x² +2x
3x² +2x -16=0
( 3x+8 ) ( x -2 ) =0
3x +8=0 —> 3x = – 8 —> x = – 8/3 —> x = – 2.6
x-2=0 —> x = 2
I hope I helped you^_^
