4) 62.8 cm^2
5) It is quadrupled
2^3 is equivalent because if you count the number of twos there are in the parentheses its 3.
Answer:
A = 20 cm^2
Step-by-step explanation:
We can find the area of a triangle from
A = 1/2 bh
A = 1/2 8*5
A = 20 cm^2
Possible Ages Sum of The Ages 1 2 36 391 4 18 231 8 9 181 3 24 282 3 12 172 4 9 152 6 6 142 2 18 223 3 8 143 4 6 13
The sum has to be 14. So it can be 2, 6, and 6 or 3, 3, and 8.
But it cannot be 3, 3, and 8 because the youngest cannot be a twin.
So it is 2, 6, and 6.
Hope this helps :)
