<em>here</em><em>,</em><em> </em><em>we</em><em> </em><em>have</em><em>;</em>

<em>=</em><em>4</em><em>x</em><em>^</em><em>2</em><em>-22x</em><em>+</em><em>3</em><em>0</em>

<em>=</em><em>4</em><em>x</em><em>^</em><em>2</em><em>-</em><em>(</em><em>1</em><em>0</em><em>+</em><em>1</em><em>2</em><em>)</em><em>x</em><em>+</em><em>3</em><em>0</em>

<em>=</em><em> </em><em>4</em><em>x</em><em>^</em><em>2</em><em>-10x-12x</em><em>+</em><em>3</em><em>0</em>

<em>now</em><em>,</em><em> </em><em>taking</em><em> </em><em>common</em><em>,</em>

<em>=</em><em>2</em><em>x</em><em>(</em><em>2</em><em>x-5</em><em>)</em><em> </em><em>-6</em><em>(</em><em>2</em><em>x-5</em><em>)</em>

<em>=</em><em> </em><em>2</em><em>(</em><em>x-</em><em>3</em><em>)</em><em>(</em><em>2</em><em>x-5</em><em>)</em><em>.</em>

Answer:

4x^2-22x+30

=2(2x^2 - 11x + 15)

=2(2x^2 -6x -5x +15)

= 2 { 2x(x-3) - 5(x-3) }

= 2 (x-3) (2x - 5)

Janelle has 4 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the
natima [27]
If the amount of time taken to go said distance is x and the amount of time taken to go back said distance is y, then the amount of miles total is 7x+3y due to that for every hour, she adds 7 miles when going there and 3 miles for walking back. In addition, since the total amount of time is 4 hours, x+y=4 as the total time spent as well as 7x=3y due to that they're the same distance. 
x+y=4
7x=3y
Dividing the second equation by 7, we get x=3y/7. Plugging that into the first equation, we get 3y/7+y=4=10y/7 (since y=7y/7). Multiplying both sides by 7 and then dividing both by 10, we get 28/10=2.8=y in hours. Since 0.1 hours is 60/10=6 minutes, and 0.8/0.1=8, 6*8=48 minutes=0.8 hours, meaning that she should plan to spend 2 hours and 48 minutes walking back

Find the missing side. Round to the nearest 10th.
const2013 [10]

Answer:

5.0

Step-by-step explanation:

Using Pythagorean Theorem:

a² + b² = c²

where a =? b= 12 in and c = 13 in

a² + (12)² = (13)²

a² + 144 = 169

a² = 169 - 144

a² = 25

a = √25 = 5

∴ a = 5.0

Pythagoras Theorem is usually applied when finding one missing side of a right-angle triangle.
