I can't answer cause u didn't show the angles
5.67 (performed on a calculator)
These angles are adjacent angels.
adjacent angels- have a common side and the same vertex.
(pictured below)
To solve this we set the sum of both angles equal to 180°. We do this because they are two adjacent angles on a straight line. The measure of a straight lines angle is 180°.
180= 5x + (x+96)
180=6x+96
84= 6x
x=14
any questions?
11 more than five of a certain number would be written as 5x+11 and it is (means equal to) twenty more than two times that number, which would be 2x+20. So the equation would be
5x+11=2x+20
-2x -2x (get the x's on one side)
3x+11=20
-11 -11 (get the numbers on one side)
3x=9
/3 /3 (divide by 3, so you can get the x by itself)
X=3 (the number is 3)
The answer is: [D]: " 24 + 2w " .

Explanation:
___________________________________________
Given: The formula for the Perimeter of a rectangle:
___________________________________________
P = 2L + 2w ;
in which:
P = perimeter ;
L = length = 12 units (given);
w = width = unknown;
_______________________________________________________
Find the perimeter, "P", in terms of "w" ; since "w" (width) is unknown; and considering the answer choices given; along with the information provided in the problem, we only have enough information to solve for the perimeter, "P", in terms of "w" ;
_____________________________________________________
So, given the formula/equation for the perimeter, "P" :
_____________________________________________________
P = 2L + 2w ; we know that: " L = 12 units " ;
_____________________________________________________
P = 2*12 + 2w = 24 + 2w ; which is: "Answer choice: [D]" .
