Answer:
Statement 2: m∠ ELD = (2x)°
Reason 4: Sum of angles on a straight line is equal to 180°
Statement 6: 2x = 56
Step-by-step explanation:
Since the first step talks about we being given m∠ ELG = 124°, the next thing we are given in the question is that; m∠ ELD = (2x)°
In statement 4,it is written that;
m∠ ELD + m∠ ELG = 180°
The reason behind this is that;
Sum of angles on a straight line is equal to 180°.
For reason 6, we are told it is a subtraction property.
Now the preceding statement gave us;
2x + 124 = 180
Which means that for subtraction property here, we will have;
2x = 180 - 124
2x = 56

A movie theater sells out 7 times per month. Chloe counted 168 sellouts at the theater. How long was Chloe recording sales?
A. 7 years
B. 2 years
C. 1 year
D. 24 years
More questions will be asked in the comments
Answers
Answer:
B. 2 years
Step-by-step explanation:
use y = mx + b
y = total number of sell outs = 168
m = sell outs per month = 7
x = months
b is not needed for this
168 = 7x
divide both sides by 7
x = 24

Which of the following numbers are less than -0.625
A) -8/5
B) -5/8
C)-0.5
*Choose all that apply*
Answers
Answer:
A) -8/5
Step-by-step explanation:
First, convert -8/5 and -5/8 to decimals
-8/5 = -1.6
-5/8 = -0.625
-0.5 is greater than -0.625 because it is closer to 0.
So, the only number less than -0.625 is -8/5, which is equivalent to -1.6
So, the correct answer is A) -8/5

What is a polynomial function?A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
Rearranging the equation x² - 51 = 14
x²- 14x -51 = 0
x² - 14x + 49 - 49 - 51 = 0
(x - 7)² = 100
x - 7 = √100
x - 7 = ± 10
Taking RHS positive,
x - 7 = 10
x = 17
Taking RHS negative
x - 7 = -10
x = 7 - 10
x = -3
Thus, the complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.

And if the appointment is x miles away from man's house the equation is
Answers
Answer:
40 miles
Step-by-step explanation:
Since we are dealing in mph, change the minutes to hr
15 min: 15/60 = .25 hrs
3 min: 3/60 = .05 hrs
:
Let t = his normal drive time to work in hrs
then
40t = the distance to work
Write a distance equation; dist = speed * time
50(t-.25 + .05) = 40t
50(t - .20) = 40t
50t - 10 = 40t
50t - 40t = 10
10t = 10
t = 1 hr normal time to work
therefore
40(1) = 40 mi to work
:
:
Confirm this by finding the dist when he went 50 mph for 48 min (.8hrs)
50(1-.25+.05) = 50(.8) = 40 mi also

Please help!!!! The roots of x^2-2x-2=0 are A.1+square root of 3 B.1+square root of 12 or C.No real roots
Answers
Answer:
A
Step-by-step explanation:
We have the equation:
[tex]x^2-2x-2=0[/tex]
We can use the quadratic formula. In this case, a = 1, b = -2, and c = -2. Hence:
[tex]\displaystyle x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-2)}}{2(1)}[/tex]
Evaluate:
[tex]\displaystyle x=\frac{2\pm\sqrt{12}}{2}[/tex]
Simplify:
[tex]\sqrt{12}=\sqrt{4}\cdot\sqrt{3}=2\sqrt{3}[/tex]
Hence:
[tex]\displaystyle x=\frac{2\pm2\sqrt{3}}{2}[/tex]
Divide:
[tex]x=1\pm\sqrt3[/tex]

Step-by-step explanation:
First we need to break down the numbers in the radicals into its factors
so
12= 3*2*2
x³=x*x*x
Which means we have
[tex]10\sqrt{3*2*2*x*x*x}=20x\sqrt{3x}[/tex]
and
[tex]2\sqrt{2*3*x*x*x*x*x} =2x^{2} \sqrt{6x}[/tex]
Because the radicand (the small number that goes up top) are the same we can just mulitply the two from here
which means we have
[tex](20x*2x^2)\sqrt{3x*6x}=40x^3\sqrt{18x^2} \\\sqrt{18x^2}=\sqrt{2*3*3*x*x} =3x\sqrt{2} \\=120x^4\sqrt{2}[/tex]
