Which expression is equivalent to "4 times the sum of 3 and x"?
A. 4(3x)
B. 4x + 3
C. 3(x + 4)
D. 4(x + 3)
My answer is C
Then wouldn't it be B or D?
looks like blind guessing to me
... and by the process of elimination we have ?????
The side length of an equilateral triangle is 10 x + 3. Which expression represents the perimeter of the triangle?
To find the expression that is equivalent to "4 times the sum of 3 and x," we can break it down into two parts: the sum of 3 and x, and then multiply it by 4.
The sum of 3 and x can be written as (3 + x). To express this sum multiplied by 4, we need to distribute the 4 to both terms inside the parentheses.
Using the distributive property, we can rewrite the expression as 4 * 3 + 4 * x.
Simplifying this further, we get 12 + 4x.
Therefore, the expression that is equivalent to "4 times the sum of 3 and x" is 12 + 4x.
Looking at the answer choices:
A. 4(3x) - This is actually 12x. Not equivalent.
B. 4x + 3 - This does not account for the sum of 3 and x. Not equivalent.
C. 3(x + 4) - This is 3x + 12. Not equivalent.
D. 4(x + 3) - This is the correct expression, 12 + 4x.
So, the correct answer is D. 4(x + 3).
Nope. C is 3 times the sum of x and 4
Which one? B or D?
