Answer:
2*2*2*2
Step-by-step explanation:
Answer:
We can check this two ways: distributing the -0.5, and plugging in a number for x.
First, we can check this by distributing the -0.5. Our equation becomes:
-1.5x -2.5 = -1.5x + 2.5
Clearly, this is not true. We can show this one more time by plugging in a number for x. I will use 2.
Now, we evaluate both sides and see if they are equal.
-3 - 2.5 = -3 + 2.5
-5.5 = 0.5
Clearly, this is not true. These expressions are not equivalent.
Step-by-step explanation:
1. 92 x 43 = 3,956
2. 524 x 51 = 26,724
3. 294 x 32 = 9,408
4. 828 x 24 = 19,872
Let ANY VARIABLE = a number
You did not provide a list of expressions.
Let n = a number
The sum of a number and 4 = n + 4.
We now multiply 3 times n + 4.
Answer: 3(n + 4)
Answer:
x ≈ 18.9
Step-by-step explanation:
using the cosine ratio in the right triangle
cos19° = 
= 
( multiply both sides by 20 )
20 × cos19° = x , then
x ≈ 18.9 ( to the nearest tenth )
