They both planted the same 8x4 =32 just the way 4x8=32
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:
x = 45/2
Step-by-step explanation:
3/8 = x/60
First, cross-multiply (multiply the numerator/denominator from one side with the denominator/numerator from the other side)
3 * 60 = 8 * x
180 = 8x
Divide both sides by 8.
x = 45/2 (this is also 22.5)
Hope this helps! Feel free to ask any questions! :)
The room increases 0.5°F every minute
How?
in 10 minutes the room increased from 65° to 70°
that means in 5 minutes the room increased from 65° to 67.5°
that's a 2.5° increase and if you divide that by 5 your get how much it increases by 1 minute; which is 0.5°
