Answer:
The width of the rectangle is 5 meters, while the length of the rectangle is 12 meters.
Step-by-step explanation:
Given that the perimeter of a rectangle is twice the sum of its lenght and its width, and the perimeter is 34 meters and its lenght is 2 meters more than twice its width, to determine the length and width of the rectangle the following calculation must be done:
(2X + 2 + X) x 2 = 34
(3X + 2) x 2 = 34
6X + 4 = 34
6X = 34 - 4
X = 30/6
X = 5
(2x5 + 2 + 5) x 2 = 34
(10 + 2 + 5) x 2 = 34
17 x 2 = 34
34 = 34
Therefore, the width of the rectangle is 5 meters, while the length of the rectangle is 12 meters.
C > because the first one equals 344 and the second one equals 14
Answer:
7(14)-11=87
2(14)-3=25
5(14)-2=68
Step-by-step explanation:
Ight Homie, lemme help you out.
To start, add (7x-11) + (2x-3) + (5x-2)
That should get you (14x-16)
Then set up the equation
14x-16=180
180 is the sum of the triangle angles. (if i said that right)
Then solve for x
14x-16=180
+16 +16
14x=196 Divide
((14x)/14)=196/14
x should equal 14.
Then replace x with 14
7(14)-11=87
2(14)-3=25
5(14)-2=68
I hope this helps. Stay safe Homie!
If angle b and angle e are the same, I guess you can write b=e ?
So you’ll have :
3x = 6x - 39
0 = 6x - 3x - 39
39 = 3x
x = 39/3
x = 13
6*40=240. 4*40=160. 240*160=38400. 38400 is your answer.
