This is to see if you understand the meanings of these words. Once you have attempted to answer these questions, we will be happy to give you feedback on your work. Although it might require more time and effort, you will learn more if you do your own work. Isn't that why you go to school?
a) (25+8)x2
b) (4+9)-(15/3)
c) (20-5)x(8+2)
d) 3xsqaureroot(9+7)
A) Double the sum of twenty-five and eight.
To express this mathematically, you would:
1. Start by finding the sum of twenty-five and eight: 25 + 8.
2. Next, you multiply the sum by two to double it: 2*(25 + 8).
The expression would be: 2*(25 + 8).
B) The quotient of fifteen and three subtracted from the product of four and nine.
To express this mathematically, you would:
1. Start by dividing fifteen by three to find the quotient: 15 / 3.
2. Next, multiply four by nine to find the product: 4 * 9.
3. Finally, subtract the quotient from the product: (4 * 9) - (15 / 3).
The expression would be: (4 * 9) - (15 / 3).
C) The difference between twenty and five multiplied by the sum of eight and two.
To express this mathematically, you would:
1. Start by finding the difference between twenty and five: 20 - 5.
2. Next, find the sum of eight and two: 8 + 2.
3. Finally, multiply the difference by the sum: (20 - 5) * (8 + 2).
The expression would be: (20 - 5) * (8 + 2).
D) Three times the square root of the sum of nine and seven.
To express this mathematically, you would:
1. Start by finding the sum of nine and seven: 9 + 7.
2. Next, find the square root of the sum: √(9 + 7).
3. Finally, multiply three by the square root: 3 * √(9 + 7).
The expression would be: 3 * √(9 + 7).
