Answer:
x^2 - 2x - 13x + 26 = (x-2)(x-13)
Step-by-step explanation:
x^2 - 15x + 26 = x^2 - 2x - 13x + 26 = (x^2 - 2x) - (13x - 26)
= x(x-2) - 13(x-2) = (x-2)(x-13)

The total distance from earth to the sun would be written as 1.0346 x 1022 7 points
miles from earth. What would this be in standard notation? *
Answer:
1.0346 x [tex]10^{22}[/tex]
Since the exponent of the scientific notation is positive, move the decimal point 22 places to the right.
10,346,000,000,000,000,000,000
The standard notation will be 10346000000000000000000.
It is given that total distance from earth to sun is 1.0346 × [tex]10^{22}[/tex]miles.
What will be the standard notation for this ?
What do you mean by the standard notation of a number ?
Standard notation of a number is when a number is written with only number digits i.e., the standard notation for 2 × [tex]10^{2}[/tex] will be 200.
The total distance from earth to the sun would be written as ;
1.0346 x [tex]10^{22}[/tex] miles.
We need to put the decimal point 22 places right ;
So , It can be written as ;
10346000000000000000000
Thus , standard notation will be 10346000000000000000000.

Someone help please!
Answer:
x = 6
Step-by-step explanation:
The sum of the angles of a triangle is 180
70+60+8x+2 = 180
Combine like terms
132 +8x = 180
Subtract 132 from each side
132+8x-132= 180-132
8x = 48
Divide each side by 8
8x/8 = 48/8
x = 6

M is the midpoint of segment AB and M (-4,-5) and A (-2,-9) find the endpoint B.
(-6, -1) b) (4,-1) c) (-2,4) d) (4,2)
The midpoint of a line segment divides a line segment into two equal parts. (T/F).
Answer:
(-6, -1)
Yes, the midpoint of a line segment divides the segment into two equal parts. True.
Step-by-step explanation:
Going from A(-2, -9) to M(-4, -5), x decreases by two units from -2 to -4; if we now go from M(-4, -5) to B, we expect that x will decrease by two more units, from -4 to -6. Thus, the x-coordinate of B is -6.
y increases by 4 from -9 to -5 (4 units) under the same circumstances. To find the y-coordinate of B, we add 4 to -5, obtaining y = -1.
The endpoint B is thus (-6, -1).

2/5 as a decimal show all work
Answer:
0.4
Step-by-step explanation:
to convert from a fraction to a decimal, we first have to make the denominator 100
we know that 5 goes into 100 20 times ;
100 ÷ 5 = 20 ;
then we have to multiply the numerator by 20 as well because we have multiplied the bottom by 20 ;
[tex]\frac{2}{5}[/tex] [tex](\frac{20}{20})[/tex]
2 x 20 = 40 ;
= [tex]\frac{40}{100}[/tex]
then to convert this into a decimal, divide the numerator by the denominator
40 ÷ 100 = 0.4

If LMP = (6x+5), NMP = (4x +18) and NML = 163°, find the measure of PMN. im sorry i dont understand geometry at all can someone help?
Answer:
PMN = 74°
Step-by-step explanation:
1. 6x + 5 + 4x + 18 = 163°
2. Combine like terms
3. 10x + 23 = 163°
4. Subtract 23 from both sides.
5. 10x = 140°
6. Divide 10 from both sides.
7. x = 14°
8. Now substitute the x in the equation for PMN with 14.
9. 4(14) + 18
10. Simplify
11. 56 + 18

Kira owes Mark $5, and Mark owes Kira $7. Which of the following statements means the same thing?
Answer:
Mark owes Kira $2.
Step-by-step explanation:
The correct answer is “Mark owes Kira $2” because first Kira owes $5 to the Mark and then Mark gives $7 to Kira. Here it can be seen that Mark is giving $2 extra and $5 is the amount which he is refunding. So the net amount $2 that the Mark gives to Kira. Therefore, the statement “Mark owes Kira $2” is justified and correct.

Please I need help....
Answer:
1. D
"n" represents the figure. For example, the equation for figure 3 would be [tex]\frac{3(3+1)}{2}[/tex] which is equal to 6 (the amount of blocks in the figure).
2. D
In the sample equations, the 9 represents figure 9. There are consistently 3 blocks in each row with an additional block at the top of the figures. So, the equation for figure 4 would be 1+(3x4) which is equal to 13. Therefore, the equation for figure 9 would be 1+(3x9).
3. A
P represents the perimeter and the n represents the figure number (like in question 1). The correct equation for the pattern would be P=4n+8. To check it, we can plug the numbers from figure 2. The equation would look like this: 16=4(2)+8
4. B
To find the answer to this problem, we just have to work backwards. We must "divide a number by 5" so we start out with [tex]\frac{n}{5}[/tex]. "n" represents the number that we do not know yet. Then we must "add 4 to the result" so the equation will now look like this: [tex]\frac{n}{5} + 4[/tex]. The problem also states that the answer is 9. Now, the final equation looks like this: [tex]\frac{n}{5} + 4=9[/tex].
If you need to, guess and check is a good way to complete multiple choice questions (until you're able to get help). I recommend asking your teacher for a more in depth explanation if you still don't understand.

Step-by-step explanation:
help!! Find the equation of the line shown
Answer:
[tex]\boxed{\bold{\huge{\boxed{y = 2x}}}}[/tex]
Step-by-step explanation:
Slope(m):
To find the slope , we need to take any two coordinates from the line.
The coordinates are (0,0) and (5,10)
Slope = [tex]\sf \frac{rise}{run}[/tex]
Slope = [tex]\sf \frac{y2-y2}{x2-x1}[/tex]
Slope = [tex]\frac{10-0}{5-0}[/tex]
Slope = [tex]\frac{10}{5}[/tex]
Slope = 2
Y-intercept(b):
Y-intercept is the point where x = 0 and that point is the origin.
So, y-intercept = 0
Slope-intercept equation:
[tex]\sf y = mx+b[/tex]
Where m = 2 and b = 0
[tex]\sf y = 2x+0[/tex]
[tex]\sf y = 2x[/tex]

The first aircraft has 89 more seats than the second aircraft. The third aircraft has 31 fewer seats than the second aircraft. If their total number of seats is 418, find the number of seats for each aircraft.
Answer:
I think number 1=209
number 2=120
number 3=89
Step-by-step explanation:
x= 1st aircraft
y=2nd aircraft
z=3rd aircraft
x=y+89
y=z+31
z=y-31
x+y+z=418
y+89+z+31+y-31=418
2y+89+z=418
2y+z=329
2y+(add z)
2y+y-31=329
3y=360
y=120
x=120+89=209
z=120-31=89
