(3x + 4)2 = 14
(3x + 4)2 means that 2 will multiply both 3x and 4
2 * 3x = 6x 2 * 4 = 8
6x + 8 = 14
Move +8 to the other side of the equation
6x = 14 - 8 Note : Moving +8 to the other side will change the sign in front of it, that is from + to -
6x = 14 - 8
6x = 6
Divide both sides by 6 because of the 6 beside the x : 6x
6x/6 = 6/6
x = 1
Note: 20 weeks = 20/52 or 5/13 of a year.
Let E = effective rate of interest
E = [1 + (r/m)]^m - 1 where r is the nominal (annual ) advertised rate; m is the number of compounding periods/year.
Let r = 0.0275
Let m = 5/13
Plug into formula and do the math.
Answer:
Option A is the correct option
BA with one sided arrow mark represent a ray
Answer:
x=5
Step-by-step explanation:
Set the 2 equations equal to each other and solve for x.
11x-28=7x-8
add 28 to both sides (-8+28=20)
11x=7x+20
subtract 7x from both sides (11x-7x=4x)
4x=20
divide both sides by 4 to isolate x (20/4=5)
x=5
