What number should be added to the expression x^2 + 14x to change it into a perfect square trinomial? Can you help me with this?
Troyanec [42]
X^2+14x

To make it as perfect square binomial first divide the numerical coefficient of 14 by 2 which is 7. Then square the result[7] which is 49 and add it to the equation
x^2+14x+49
After that think of a number that has a square root of 49 then when u multiply the second term in the perfect square by the first and 2 it results to 14. So the answer is
[x+7]^2

A consumer affairs investigator records the repair cost for 44 randomly selected TVs. A sample mean of $54.41$ 54.41 and standar
anzhelika [568]

Answer:

($47.245; $61.575)

Step-by-step explanation:

Mean sample repair cost (X) = $54.41

Standard deviation (s) = $28.89

Sample size (n) =44

Z-score for a 90% confidence interval (z) = 1.645

The confidence interval, assuming a normal distribution, is given by:

X \pm z\frac{s}{\sqrt{n}}

Applying the given data, the lower (L) and upper (U) bounds of the interval are:

L=54.41-1.645*\frac{28.89}{\sqrt{44}} \\L=\$47.245\\U=54.41+1.645*\frac{28.89}{\sqrt{44}} \\U=\$61.575

The confidence interval is I = ($47.245; $61.575)

Is 18-3(2p+4) -3p equivalent to 3(2-3p)
Murljashka [212]

Answer:

<u>Yes they are equivalent.</u>

Step-by-step explanation:

Use PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

Distribute or multiply -3 with 2p and 4 to get -6p and -12.

You will then have 18-6p-12-3p, simplify to get 6-9p

For the second equation multiply 3 with 2 and -3p, you will then get 6-9p as well.

They are equal, hope the helps ;)
