<em>Presuming you mean y = -2x^2 - 8x - 13</em>
Firstly, put the x terms in parentheses and factor out -2:
Next, we want to make what's inside those parentheses a perfect square. To do this, divide the x coefficient by 2 and square that result. In this case, that result is 4. Add 4 to the inside of the parentheses, and add 8 to the outside of the parentheses to balance it out. (Since when foiled, 4 x -2 = -8)
Next, factor what's inside the parentheses, and <u>your final answer will be </u>
Madison=3x
Daryl=x
3x+x=$41.00
4x=$41.00
X=$41.00/4
X=$10.25
Madison =3*$10.25
=$30.75
Daryl=$10.25
Answer:
Hi there!
Your answer is:
width=15
Length=25
Step-by-step explanation:
L=2w-5
P=80
Perimeter formula
L+L+W+W=P
(2w-5)+(2w-5)+w+w=80
6w-10=80
+10
6w=90
/6
w=15
Plug in width in length formula
L=2w-5
2(15)-5
30-5
L=25
Answer: B) There is sufficient evidence to support the claim μ=584
Step-by-step explanation:
Let be the population mean age of professors at a university.
As per given , we have
Null hypothesis :
If we fails to reject null hypothesis , it means that we need to accept it.
It means we have sufficient evidence that null hypothesis is true.
i.e. There is sufficient evidence to support the claim μ=584
Hence, the correct answer is A) There is sufficient evidence to support the claim μ=584.
