Answer:
9(4x - 1)
Step-by-step explanation:
The given linear expression is:
36x - 9
Since, 36 can be written as 9 times 4, we can rewrite the above expression as:
9(4x) - 9
Taking 9 as common, the expression changes to:
9 (4x - 1)
This linear expression can no linger be factorized further.
So,
36x - 9 = 9(4x - 1)

Answer: 1692
Step-by-step explanation:
Formula to find the sample size :
Given : Confidence level :
⇒ significance level =
z-value for 90% confidence interval (using z-table)=
Prior estimate of the population proportion (p) of customers who keep up with regular vehicle maintenance is unknown.
Let we take p= 0.5
Margin of error : E= 2%=0.02
Now, the required sample size will be :
Simplify , we get
Hence, the required sample size = 1692
Answer:
<h2>x=3</h2>
Step-by-step explanation:
Let's solve your equation step-by-step.
8.88=−2.22(x−7)
Step 1: Simplify both sides of the equation.
8.88=−2.22(x−7)
8.88=(−2.22)(x)+(−2.22)(−7) (Distribute)
8.88=−2.22x+15.54
Step 2: Flip the equation.
−2.22x+15.54=8.88
Step 3: Subtract 15.54 from both sides.
−2.22x+15.54−15.54=8.88−15.54
−2.22x=−6.66
Step 4: Divide both sides by -2.22.
−2.22x
/−2.22
=
−6.66
/−2.22
x=3
