Answer:
n = -2
Step-by-step explanation:
6(2n - 3) - 2(6n + 1) = 10n
multiply the brackets
6*2n - 6*3 - 2*6n - 2*1 = 10n
12n - 18 - 12n - 2 = 10n
add or subtract the like terms
0 - 20 = 10n
shift 10 to the right hand side .REmember when u shift multiplication changes to division.
-20 / 10 = n
-2 = n
Answer:
The two expression to represent area is (5 x - 10) sq. units or 5( x- 2) sq. units
Step-by-step explanation:
Here, the length of the rectangle = (x-2) units
The width of the rectangle = 5 units
Now, AREA OF A RECTANGLE = LENGTH x WIDTH
So, here AREA = 5 ( x- 2)
= (5 x - 10) sq. units
( as by Distributive property: A (B-C) = AB - AC)
Hence, the two expression to represent area is (5 x - 10) sq. units or 5( x- 2) sq. units
Answer:
Roughly 70.29 degrees
Step-by-step explanation:
Equation:
(2x+27)+(2x-11)+3x = 180
7x + 16 = 180
7x = 164
x ~ 23.43
Angle C:
3x
3（23.43)
70.29
