Answer:
203 square inches.
Step-by-step explanation:
First you have to find the area of the triangles, and you do so by using the formula A = (B·H)/2, where the a represents area, b represents base, and h represents height. Assuming all of the triangles are the same, you multiply 7 by 11 and then divide by 2 (which equals 38.5) and then multiply that by 4 (which equals 154) and then you have the area of all four triangles combined. Then to find the area of the cube you simply square 7, which results in 49, and then add that to the area of the triangles, which leaves you at 203. 203 square inches is your answer.
Answer:
(2x+5)(x+4)
Step-by-step explanation:
Any number, either positive or negative raised to the power of 0 is equal to 1.
For U= (2,3,4,5,6,7,8), X=(2,3,4,5), state X'=

Answer:
X' = {6,7,8}
Step-by-step explanation:
X' is the set that contains the elements that are in set U bot NOT in set X.
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 :)
