Answer:
5
Step-by-step explanation:
To first begin to solve this problem, keep this in mind:
- and - = +
+ and + = +
+ and - = -
- and + = -
To avoid confusion it's best to remember the above information. Also the information shows that the signs which are the same are positive so they have an addition sign and the signs that are not the same are negative so they have a minus sign.
The value of 3-(-2)
3-(-2)
Remove the brackets.
3--2
As the rule states above, signs that are the same are POSITIVE so they have an ADDITION sign.
3--2
= 3+2
= 5
107 as the median is the middle number and the middle number falls between 106 and 108 therefore it’s 107 :)
The product of 4xy and y² + 2x can also be written as
4xy(y² + 2x)
When we have brackets like this, we multiply whatever is left of the brackets by everything inside.
1) 4xy multiplied by y²
4xy x y² = 4xy³
2) 4xy multiplied by 2x
4xy x 2x = 8x²y
3) Add together 4xy³ and 8x²y
4xy³ + 8x²y
The Answer is 3 Inches.
The Equation is 15×9×3.14÷3=141.3 cubic inches(volume)
The Formula is h×r²×π÷3=V
