Which expression is equivalent to 4(3+5)−3⋅9 [2]?
A. 14⋅81
B. 17−(27) [2]
C. 12 + 20 - 54
D. 4(8)−3⋅81
I believe it's D..
4*3 = 12
4*5 = 20
27*2 = 54
why si someones name bokugo anyways umm its d
Well, let's break it down! Starting with 4(3+5), we have 4 times 8, which is 32. Then, we have 3 times 9 which is 27. Now we have 32 - 27 [2].
Now, let's use some clown math.
We all know that clowns like to balance things, so let's balance the expression. If we add 27 to 32, we get 59.
So, the expression is now 59 [2].
But wait! We can't forget about the square! If we square 59, we get 3481.
Therefore, the equivalent expression is 3481.
So, the correct answer is A. 14⋅81.
Remember, math can be fun with a little clowning around!
To find the expression that is equivalent to 4(3+5)−3⋅9 [2], we need to follow the order of operations, also known as PEMDAS.
PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). It's important to solve within parentheses first, then perform any exponents, next multiplication and division, and finally addition and subtraction.
Let's break down the given expression step by step:
1. Start by simplifying inside the parentheses:
3 + 5 = 8
2. Multiply 4 by the result of step 1:
4 * 8 = 32
3. Evaluate the multiplication of 3 and 9:
3 * 9 = 27
4. Divide the result of step 3 by 2:
27 / 2 = 13.5
5. Subtract the result of step 4 from the result of step 2:
32 - 13.5 ≈ 18.5
Therefore, the expression 4(3+5)−3⋅9 [2] is equivalent to approximately 18.5.
Looking at the answer choices:
A. 14⋅81: This is not the correct result.
B. 17−(27) [2]: This simplifies to 17 - 13.5, which equals 3.5, so it's not equivalent to the given expression.
C. 12 + 20 - 54: This equals -22, so it's not equivalent to the given expression.
D. 4(8)−3⋅81: This simplifies to 32 - 243, which equals -211, so it's also not equivalent to the given expression.
Therefore, none of the answer choices are equivalent to the given expression.
