<h2>
Value of x is 2 </h2>
Step-by-step explanation:
Surface area is given by 2x²+48x+88
We need to find x when surface area is 192.
A = 2x²+48x+88
2x²+48x+88 = 192
2x²+48x- 104 = 0
x²+ 24x - 52 = 0
( x - 2 ) ( x + 26 ) = 0
x = 2 or x = -26 not possible
Value of x is 2
Answer:
8
Step-by-step explanation:
sqrt4^2+sqrt4^2=4+4 the square root and power of 2 cancel out
The best description is ...
the discriminant is zero.
<h3>
Answer: -14 degrees Fahrenheit</h3>
Explanation:
Draw a vertical number line. At the center is 0. Anything above this marker represents positive temperatures. Anything below 0 is negative. So we'll have -8 below 0. Move 6 spaces down to go from -8 to -14. You can think of it as moving 6 floors down a building to go from basement level 8 to basement level 14.
Answer:
(-3,-12)
Step-by-step explanation:
Multiply the first equation by three to match the second equations y-term
The y-terms cancel out
Add the x-terms with each other and the terms after the equal sign as well
Divide -57 by 19
Input your x-term (-3) into one of the two first equations and multiply
Either:
Simplify your terms
Divide
