L=4+W
46=2L+2W
46=2(4+W)+2W
46=8+2W+2W
46=8+4W
38=4W
9.5=W
L=4+9.5
L=13.5 in.
Hope this helps. I can explain more if needed!!
<u><em>Answer:</em></u>
D. 60
<u><em>Explanation:</em></u>
<u>The general form of the quadratic equation is:</u>
ax² + bx + c = 0
<u>The given equation is:</u>
3x² + 6x = 2
This can be rewritten as:
3x² + 6x - 2 = 0
<u>By comparison, we can find that:</u>
a = 3
b = 6
c = -2
<u>Now, the discriminant of a quadratic equation is given by:</u>
b² - 4ac
<u>Substitute with the given values to get the discriminant for the given equation as follows:</u>
b² - 4ac = (6)² - 4(3)(-2)
= 36 - (-24)
= 36 + 24
= 60
Hope this helps :)
To find the ordered pair solution, you need to find the zero(s) (which are the x-values for which y is equal to zero). This is called the Zero Product Property. Here's the math:
-2x-y=4 convert the equation into slope form
-y=2x+4 multiply both sides by -1
y=-2x-4 convert into factored form
y=-2(x+2) now, we need to find what x equals that makes y equal zero
0=-2(x+2) replace y with zero
0/-2=x+2 divide both sides by -2
-2=x x=-2 when y=0
Therefore, the zero of the equation (aka the solution) is the ordered pair (-2,0).
Answer: (-2,0)
If you have access to a graphing calculator, you can just convert the equation to y=mx+b form and enter it as a function. The solution is wherever the graph intercepts the x-axis. Hope this helps!
