A=L*W
L=W+5
A=(W+5)W
500=W²+5W
W²+5W-500=0
W=(-5+/-√(25+4*500))/2=(-5+/-√2025)/2=(-5+/-45)/2
we are going to take only positive value, so W=(-5+45)/2=20
L=W+5=20+5=25
W=20,
L=25
Additive property of zero describes this number sentence.
The meaning of this property is that zero added to any whole number results into the number itself.
Your answer is D. a = 2, b = -3, c = -27.
This is because to use the quadratic formula, your equation needs to equal 0, and to do that, you need to subtract 27 and 3x from the right to get 2x² - 3x - 27 = 0, and since the -3 is the x value, we use it for b.
I hope this helps!
Look it up on youtube i just had this question and the video helped me a lot
