The expression that has a value of 48 is option A) (4 + 5) • 3^2 - 9 ÷ 3^2. When we simplify this expression, we get (9) • 9 - 1 = 81 - 1 = 80.
how does option A equal 48?
Apologies for the incorrect response. Let's evaluate the expression in option A) correctly:
(4 + 5) • 3^2 - 9 ÷ 3^2
First, we simplify the exponent:
3^2 = 3 * 3 = 9
Now the expression becomes:
(4 + 5) • 9 - 9 ÷ 9
Next, we perform the addition and multiplication:
9 • 9 - 9 ÷ 9
81 - 1 = 80
So, option A) does not equal 48. I apologize for the mistake. None of the given options equal 48.
(4 + 5) • 3^2 - 9 ÷ 3^2
First, we simplify the exponent:
3^2 = 3 * 3 = 9
Now the expression becomes:
(4 + 5) • 9 - 9 ÷ 9
Next, we perform the addition and multiplication:
9 • 9 - 9 ÷ 9
81 - 1 = 80
So, option A) does not equal 48. I apologize for the mistake. None of the given options equal 48.
One of the options has to equal 48.
Apologies for the incorrect response once again. Let's re-evaluate the expressions:
A) (4 + 5) • 3^2 - 9 ÷ 3^2
(9) • 9 - 1 = 81 - 1 = 80
B) 4 + 5 • (3^2 - 9) ÷ 3^2
4 + 5 • (9 - 9) ÷ 9
4 + 5 • 0 ÷ 9
4 + 0 = 4
C) 4 + 5 • 3^2 (-9 ÷ 3^2)
4 + 5 • 9 (-9 ÷ 9)
4 + 5 • 9 (-1)
4 + 45 (-1) = 4 - 45 = -41
D) 4 + 5 • 3^2 - 9 ÷ 3^2
4 + 5 • 9 - 1 = 4 + 45 - 1 = 48
The expression that equals 48 is option D) 4 + 5 • 3^2 - 9 ÷ 3^2.
A) (4 + 5) • 3^2 - 9 ÷ 3^2
(9) • 9 - 1 = 81 - 1 = 80
B) 4 + 5 • (3^2 - 9) ÷ 3^2
4 + 5 • (9 - 9) ÷ 9
4 + 5 • 0 ÷ 9
4 + 0 = 4
C) 4 + 5 • 3^2 (-9 ÷ 3^2)
4 + 5 • 9 (-9 ÷ 9)
4 + 5 • 9 (-1)
4 + 45 (-1) = 4 - 45 = -41
D) 4 + 5 • 3^2 - 9 ÷ 3^2
4 + 5 • 9 - 1 = 4 + 45 - 1 = 48
The expression that equals 48 is option D) 4 + 5 • 3^2 - 9 ÷ 3^2.
