So, u would start by expanding the bracket and ignoring the 2 at the moment.
(x+9)(x+9)= x^2-18x+81(using the foil method!

Then u would put 2 at the front to get:
2(x^2+18x+81)
= 2x^2+36x+162

Find the mean of the first four test scores first.
(Add all numbers in set and divide by how many numbers there are)
81 + 87 + 71 + 89 = 328 / 4 = 82

Then, find the mean with the 85 added as the fifth term.
81 + 87 + 71 + 89 + 85 = 413 / 5 = 82.6

The impact that the 85 had on the mean test score was that the mean/average increased by 0.6.

What is the value of x please help me
Tju [1.3M]

Answer:

<h2>x = 4</h2>

Step-by-step explanation:

ΔLMN and ΔPMQ are similar. Therefore thw sides are in proportion:

\dfrac{LM}{PM}=\dfrac{NM}{QM}

We have:

LM = 3 + 9 = 12

PM = 9

NM = x + 12

QM = 12

Substitute:

\dfrac{12}{9}=\dfrac{x+12}{12}                <em>cross multiply</em>

9(x+12)=(12)(12)

9(x+12)=144             <em>divide both sides by 9</em>

\dfrac{9(x+12)}{9}=\dfrac{144}{9}

x+12=16             <em>subtract 12 from both sides</em>

x=4
