Answer:70
Step-by-step explanation:82+82+82+70=316/4=70
To find the average of multiple number you have to add up all of the numbers and then divide by the amount of numbers (in this case 4). You could easily do this by guess&check in a calculator.
A(7, -2) B(-4, 9) C(-3,-1)
AB² = (7 - -4)² + (9 - -2)² = 121 + 121 = 242
AC² = (7 - -3)² + (-2 - -1)² = 100 + 1 = 101
BC² = (-3 - -4)² + (9 - -1)² = 1 + 100 = 101
Since AC² + BC² ≠ AB² this isn't a right triangle
It is clearly an isosceles triangle because AC² = BC²
Answer: Isosceles
Just plug in the numbers.....
3(100) + 9(39) = then multiply
300 + 351= then add them
651..... 651 is your answer
0.5 kilograms= 500 grams.
20c+45a
20(10)+45(12)
200+540
740.
There is not enough medicine in the bootle, you will need 240 grams more.

The answer is is 4.2 because the 2 rounds up to 3 and the 3 does not round up the four so four does not round up the 2 so it is 4.2
