Step-by-step explanation:
Given
Represent solid beads with S and clear beads with C
So:
Required
Select operations that give an equivalent ratio
First, we need to get the unit ratio
Divide through by 4
-- This means that, after any operation. The equivalent ratio must be 2: 5
Option A: Add 2 to S and 2 to C
Perform the operation
Divide through by 2
Option B: Subtract 8 from S and 6 from C
Perform the operation
Option C: Multiply S and C by 2
Perform the operation
Divide through by 8
Option D: Divide S and C by 4
Perform the operation
Option E: Multiply S and C by 18
Perform the operation
Divide through by 72
<em>From the calculations above, options C, D and E gave an equivalent of 2:5.</em>
Answer:
The quotient is .
Step-by-step explanation:
We do this as the simple division that we do with the integers.Find a quotient that is same as the first on multiplying with the divisor term of the dividend.
Divisor = x+1.
Dividend = 2x²-3x-5
We found that on multiplying 2x with x+1 we will get 2x²+2x and then subtracting it from dividend we will get -5x-5. We found that only multiplying the divisor with -5 we will get -5x-5 and on subtracting it from the dividend the the remainder will be 0. Hence the quotient is 2x-5.
