Step-by-step explanation:
4x+17=23
4x=23-17
4x=6
x=6/4
Answer:
Option A. x + 3
Step-by-step explanation:
From the question given above, the following data were obtained:
Area (A) = x² + 2x – 3
Width (W) = x – 1
Lenght (L) =?
The area of a rectangle is given by:
Area (A) = length (L) × Width (W)
A = L × W
With the above formula, we can obtain the lenght of the rectangle as follow:
Area (A) = x² + 2x – 3
Width (W) = x – 1
Lenght (L) =?
A = L × W
(x² + 2x – 3) = L(x – 1)
Divide both side by (x – 1)
L = (x² + 2x – 3) / (x – 1)
Please see attached photo for explanation
L = x + 3
Thus, the length of the rectangle is x + 3
Answer:
A,D,E
Step-by-step explanation:
scaled copy means the ratio of the two lengths would be same proportional constant.
The proportionality constant for Rectangle A is:
12/3 = 4
So any scaled version will have this proportionality constant same (4).
let's check:
A) 6/1.5 = 4 (OK)
B) 10/2 = 5 (NOT OK)
C) 13/4 = 3.25 (NOT OK)
D) 18/4.5 = 4 (OK)
E) 80/20 = 4 (OK)
So, correct options are A, D, and E
