Answer:
8
Step-by-step explanation:
401.92 divided by 16 = 25.12
25.12 divided by 3.14 is 8
-7/-9 is equivalent to -14/-18. Multiply the denominator and numerator by the same number(I used 2)
Solve for x:
-3 (3 x + 15) - (x + 10) = 35
-3 (3 x + 15) = -9 x - 45:
-9 x - 45 - (x + 10) = 35
-(x + 10) = -x - 10:
-9 x + -x - 10 - 45 = 35
Grouping like terms, -x - 9 x - 45 - 10 = (-9 x - x) + (-45 - 10):
(-9 x - x) + (-45 - 10) = 35
-9 x - x = -10 x:
-10 x + (-45 - 10) = 35
-45 - 10 = -55:
-55 - 10 x = 35
Add 55 to both sides:
(55 - 55) - 10 x = 55 + 35
55 - 55 = 0:
-10 x = 35 + 55
35 + 55 = 90:
-10 x = 90
Divide both sides of -10 x = 90 by -10:
(-10 x)/(-10) = 90/(-10)
(-10)/(-10) = 1:
x = 90/(-10)
The gcd of 90 and -10 is 10, so 90/(-10) = (10×9)/(10 (-1)) = 10/10×9/(-1) = 9/(-1):
x = 9/(-1)
Multiply numerator and denominator of 9/(-1) by -1:
Answer: x = -9
Step-by-step explanation:
<h2><u>Given :-</u></h2>
x-1-(x-1)²+ax-a
<h2><u>To find :-</u></h2>
Factorize the expression ?
<h2><u>Solution :-</u></h2>
Given expression is x-1-(x-1)²+ax-a
It can be written as
(x-1)-(x-1)²+(ax-a)
=> (x-1)-(x-1)(x-1)+a(x-1)
=> (x-1)[1-(x-1)+a]
=> (x-1)(1-x+1+a)
=> (x-1)(2-x+a)
<h2><u>Answer:-</u></h2>
x-1-(x-1)²+ax-a = (x-1)(2-x+a)
Hope this helps!!
