Answer:
x=12
Step-by-step explanation:
3x=2x+12
-2x from each side
x=12
Answer:
517
Step-by-step explanation:
The radius of a circle is just half of the diameter (1/2d = r)
1034/2 = 517
Answer:
x = -0.62 and x = 4.29
These values are approximations !
Step-by-step explanation:
You can not use Factoring to solve this equation. Perhaps you did not use the exact notation as in the original question?
Anyway, to solve it, you can still use the ABC formula.
3x²-11x-6=0
a = 3
b =-11
c = -6
x = [11 + √{121 -4(3 *-6)} ]/ 2*3
x = [11 + √{121 -4(-24)} ]/ 6
x = [11 + √{121 + 96} ]/ 6
x = [11 + √{217} ]/ 6
x = 4.29 This is an approximation !
x = [11 - √{121 -4(3 *-6)} ]/ 2*3
x = [11 - √{121 -4(-24)} ]/ 6
x = [11 - √{121 + 96} ]/ 6
x = [11 - √{217} ]/ 6
x = -0.62 This is an approximation !

Answer:
Question 1. If the perimeter of Rectangle ABCD is 34y+2. What is the width?
Question 2. What is the area of Rectangle ABCD in terms of y?
Question 3. If the perimeter of the rectangle is 70. What is it’s area?
Question 4. What are the length and width of the rectangle?
Let
be the constant factor between terms, so that


and so on, with

(notice how the exponent and the subscript add to
)
Then

so if

then

Now,

so the third term in the sequence is 30.
