Answer:
A. Millimeter
Step-by-step explanation:
eyelashes are very small
96/6=16
Each side has area 16 sq cm.
Each edge length is sqrt(16)=4 cm
Answer:
14,15,16
Step-by-step explanation:
Let x be the first number
Consecutive means in a row
x+1 is the second number
x+2 is the third number
x+ x+1 + x+2 = 45
Combine like terms
3x+3 = 45
Subtract 3 from each side
3x+3-3=45-3
3x = 42
Divide each side by 3
3x/3 = 42/3
x =14
The first number is 14
The second number is 14+1 = 15
The third number is 14+2 =16
Answer:
1. 4x + 6
2. -15x + 11
5. -x + 4
6. -4x + 7
9. 5x - 2
12. x + 16
Step-by-step explanation:
Remove the parenthesis for each one so everything's out in the open. Next, you group like terms. The numbers with variables on one side, and the other numbers on the other side. For example:
x + 3x - 2 + 8
Then, you combine like terms:
4x + 6
That's mostly how you do each one.
"if equals are divided by equals, the results are equal." This is a corollary of the distributive property for multiplication.
