Answer:

<u>Given</u>:- x = 3 + √5 ; y = 3 - √5

<u>Expression</u>:- x² - 2xy + y²

  • (3 + √5)² - 2 × 3 + √5 × 3 - √5 + (3 - √5)²
  • 9 + 5 + 6√5 - 2 × (3² - √5²) + 9 + 5 - 6√5
  • 14 + 6√5 - 2 × (9 - 5) + 14 - 6√5
  • 28 - 2 × 4
  • 28 - 8
  • 20

Hence, Value of expression x² - 2xy + y² is 20.

Solve the measure of an angle is 161°. what is the measure of a supplementary angle?
lions [1.4K]
Supplementary angles sum up to 180°, suppose the supplement of 161° is x. Then
161+x=180
solving for x we subtract 161 from both sides
161-161+x=180-161
x=19
thus the supplement is 19°

The football team has a total of 350 jerseys. There are 154 ​medium-sized jerseys. What percent of the jerseys are​ medium-sized
KonstantinChe [14]

Answer:

Step-by-step explanation:

Given : The total number of jerseys = 350

The number of medium-sized jerseys = 154

Then, the percent of the jerseys are medium-sized jerseys will be :-

\begin{gathered}\dfrac{\text{Number of medium-sized jerseys }}{\text{Total jerseys}}\times100\\\\=\dfrac{154}{350}\times100\\\\=0.44\times100=44\%\end{gathered}

Total jerseys

Number of medium-sized jerseys

×100

=

350

154

×100

=0.44×100=44%

<h3>Therefore , the percent of the jerseys are medium-sized jerseys = 44%</h3>
