i need help with writing expressions

A) double the sum of 25 and 8
i think it is(2x25+8)
B) the quotient of 15 and 3 subtracted from the product of 4 and 9
i think it is (5/3-4x9)
C) the difference between 20 and 5 multiplied by the sum of 8 and 2
I think it is 20-5x8+2
D) 3 times the square root of the sum of
9 and 7 i think it is (3x9(2)+7(2)
(2) = squared as i don't know how to write that on a computer.

any help would be greatful or just letting me know i'm on the right track i just can't seem to get it

Millie, unfortunately all your answers are incorrect.

A) should be 2(25+8)
B) watch the "subtracted from" part
(4)(9) - (15/3)
c) you will need brackets
(20-5)(8+2)
D) 3√(9+7)

Let's go through each expression and verify if they are correct or need some adjustments.

A) To double the sum of 25 and 8, you need to first find the sum and then multiply it by 2. The correct expression would be: 2 * (25 + 8).

B) To find the quotient of 15 and 3 and subtract it from the product of 4 and 9, you need to calculate the product first and then subtract the quotient. The correct expression would be: (4 * 9) - (15 / 3).

C) To find the difference between 20 and 5 and multiply it by the sum of 8 and 2, you need to calculate the sum first and then find the difference. The correct expression would be: (20 - 5) * (8 + 2).

D) To find 3 times the square root of the sum of 9 and 7, you need to first find the square root of the sum and then multiply it by 3. The correct expression would be: 3 * √(9 + 7).

So, the revised expressions are:
A) 2 * (25 + 8)
B) (4 * 9) - (15 / 3)
C) (20 - 5) * (8 + 2)
D) 3 * √(9 + 7)

When writing mathematical expressions online, you can indicate squaring by using the "^" symbol. For example, to square a number, you would write "number^2".
