Hey there! :)
5n(3n - n + 8)
Simplify.
(5n × 3n) + (5n × -n) + (5n × 8)
Simplify.
(15n²) + (-5n²) + (40n)
Remove parenthesis
**Remember : a negative times a positive is always a negative, a positive times a positive is a positive, and a negative times a negative is a positive**
15n² - 5n² + 40n
Combine like terms.
(15n² - 5n²) + 40n
Simplify.
10n² + 40n → final answer :)
~Hope I helped!~
Answer:
Step-by-step explanation:
In order to determine the number of wax cubes needed to make the candle, we divide the volume of the pyramid by the volume of the cube. That is,
number of wax = volume of mold / volume of wax
The formulas are,
number of wax = (1/3)Ah / s³
Where A is the area of the base, in this case 9 cm x 9 cm which is equal to 81 cm². Substituting the known values from the given above,
number of wax = (1/3)(81 cm²)(10 cm) / (4 cm)³ = 4.21
Thus, approximate number of wax should be 4.21. If we are to round this off to the nearest whole number, we will get 5 (considering that we want rather to have excess than missing items)
Answer:
x = 1 . 14
Step-by-step explanation:
5x + 7 + 2x + 1
5x + 2x + 7 + 1
= 7x + 8
= x = 8 / 7
x = 1.1 4
Hope this answer helps you :)
Have a great day
