Answer:
2(x + 10)
Step-by-step explanation:
The sum of x and 10 is x + 10
The product of 2 and x + 10 means multiply them, thus
2 × (x + 10)
= 2(x + 10) ← parenthesis indicates x and 10 are added before being multiplied by 2
We know that a triangle has three sides, all the same length (its equilateral, after all)
The equation to find the length of each side is
Perimeter divided by 3
or in this case
48.6 divided by 3=16.2cm (don't forget the unit)
Hope that helps :)
Answer:
Since there are 4.5*10^2 grams of trash per day per person, we multiply that by 3.2*10^6 for everyone in the US and then multiply that by 365 to get how much in a year, which is 525600000000 or 5.256*10^11 (I think it's 11)
Step-by-step explanation:
1 m = 100 cm
1 cm =
m
1 cm² =
m²
5 cm² =
m²
Hence, 5 cm² is 0.0005 m².
The answer is D , I promise
