Answer:
(y+1)(2y−3)
Step-by-step explanation:
Bob gives 3/4 of the beads to his friend
2/3 of the beads bob now had are red
Work out how many green beads bob now has
Now from 120 beads, Bob has 10 green beads.
Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
Total number of beads = 120,
Since, Bob gives 3/4 of the beads, So the remaining beads,
= 120×1/4
=30
Now from these 30 beads, 2/3 beads are red,
So red beads are = 30×2/3 = 20
Therefore, green beads are = 30-20= 10
Bob has 10 green beads.

Answer:
The answer is 1728
Step-by-step explanation:
Given the expression 5(14 - 2) to the 2nd power over 2, this can be written mathematically as;
{5(14 - 2)}²/2
Step1: we will solve for the function in bracket to have;
{5(12)}²/2
Step 2: we will take the square of the values in bracket since they are both raise to power of 2 to have;
(5²×12²)/2
= 25×144/2
Step 3: simplify the resulting equation to give;
= 24×72
=1728
The simplified form of the expression is 1728
