You just solve it like a normal multiplication problem and then start putting the decimal begin the answer and place it 3 numbers forward
The given expression can be simplified in many ways by grouping like terms. The simplest form is obtained by factoring out a²b which gives us the following expression.
a²b(7 + 10b +14b²)
4 is the answer! Because if you have 10 slices of pizza and you ate 40% of it you need to divide 40 by 10 and you get 4 as your answer!!!
The answer is 224.7 you got to turn 30% into decimal which is 0.30
then multiply 0.30 and 749 which equals 224.7
The manager could perform scalar multiplication on Matrix A, using the scalar 1.15.
Increasing the price by 15% would mean we are taking 100% of the value + another 15%; 100+15 = 115%; 115% = 115/100 = 1.15.
Multiplying every value in Matrix A by 1.15 will give the price raised by 15%.
