I think it is because they are both different differences
If i= V-1, then -117 expression is equal to 9i(13i)
Step-by-step explanation:
Original problem : 9i(13i)
=> 117
(Multiply)
=> 117 * -1
=>
= -1
=> -117
If i= V-1, then -117 expression is equal to 9i(13i)
Answer:
The slope of the line is constant. This is because all straight lines have a constant slope. The slope of this line is 1/3. When you use the legs to measure, the horizontal legs of the triangle, they increase in length by 3 units from the previous triangle. The vertical legs of the triangle also increase by 1 with each added triangle. Both of these observations support that the slope of the line is a constant 1/3.
Step-by-step explanation:
I know you were going to copy and paste so i put all above. Hope it helps you.
Did two of them for you as reference for the rest.
Explanation for #1
The sum of all the angles in a triangle is 180. Simply add the given angles. Take 180 and subtract the sum of the given angles
180 - (58 + 47) = 75
Missing angle is 75
Explanation for #4
A straight angle is 180 degrees. Same thing as the first: add the given angles then take 180 and subtract it.
Then take 180 <em>again </em>and subtract the answer you got from the first step.
180 - (21 + 34) = 125
180 - 125 = 55
The missing angle is 55
Answer:
0 = 2x² - 23x + 45
Step-by-step explanation:
0 = (x - 5/2)(x - 9)
0 = x² - 5/2x - 9x + 45/2
0 = 2x² - 23x + 45
