Answer: No
Step-by-step explanation:
Add 2 sides together. If the sum of greater than the length of the 3rd side for all 3 options it can form a right triangle if it doesn’t than it can’t:
9 + 12 = 21 which is not greater than the 3rd side length of 21 so this cannot form a right triangle.
What is the following sign ??? and the rest of the question I'm sure I can help please provide more info
Answer:
10. X=3
11. FG=15
12. QS=34
Hope this helps
Step-by-step explanation:
10. 8x+11=12x-1
8x-12x=-1-11
-4x=-12
x=3
11. 11x-7=3x+9
11x-7=-9+7
8x=16
x=2
Substitute the (x)
11(2)-7 =15
12. 5x-3=21-x
5x+x=21+3
6x=24
x=4
Substitute the (x)a
5(4)-3=17
21-(4)=17
17+17=34
Since .9999 is less than 100, the nearest hundred is 0.
