Answer: All real numbers are solutions
Step-by-step explanation:
first lets distributive the 2(4x+1) to get 8x+2 because 2*4x= 8x and 2*1= 2
now the equation is 8x+2-5x+2= 3x+4
(COMBINE LIKE TERMS)
8x-5x=3x
2+2= 4
now the equation is 3x+4= 3x+4 (this means all real nubers are solutions)
Ok, so for 9/2,just divide,which will get you 4 1/2 since 2 can only go into 9 4 times.then for 10/7, do the same thing,and you will get 1 3/7 since 7 can only go into 10 once
Answer:
The last equation x2 - 2x -4 = 0
has solution (x - 1)^2 - 5 = 0, x = 1 + root(5) or x = 1 - root(5)
Step-by-step explanation:
If a quadratic function has roots 1 and 5
f(x) = (x -1)(x- 5)
f(x) = x^2 - 6x + 5
Unless you meant. -4 and 6 ?
g(x) = (x + 4)(x - 6)
g(x) = x^2 -2x -24
-------------------------
Or did you mean x = 1 and x =4 ?...
x^2 + 2x + 4 = 0 : complete square x^2 + 2x + 1 + 3 = 0, (x+1)^2 + 3 = 0
x^2 - 2x + 4 = 0 : complete square: (x -1)^2 + 3 = 0
0x^2 + 2x - 4 = 0, 2x - 4 = 0, x = 2
x^2 - 2x - 4 = 0 becomes: x^2 - 2x + 1 - 1 -4 = 0 ; (x - 1)^2 - 5 = 0
Yes half of twelve is 6 and 6 miles is more than 5.75 miles
Answer:
X=30, Scalene
Step-by-step explanation:
A circle is 360, The triangle is in the circle.
Part A:3x+30+2x+20+5x+10=360
10x+60=360
<u>-60=-</u><u>60</u>
10x=300
x=30
Part B:<em>Side BA</em><em> </em><em>is</em><em> </em><em>3</em><em>(</em><em>3</em><em>0</em><em>)</em><em>+</em><em>3</em><em>0</em><em>=</em><em>1</em><em>2</em><em>0</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>Side</em><em> </em><em>BC</em><em> </em><em>is</em><em> </em><em>2</em><em>(</em><em>3</em><em>0</em><em>)</em><em>+</em><em>3</em><em>0</em><em>=</em><em>9</em><em>0</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>Side</em><em> </em><em>AC</em><em> </em><em>is</em><em> </em><em>5</em><em>(</em><em>30</em><em>)</em><em>+</em><em>10</em><em>=</em><em>160</em>
All three sides are unequal
