25) It is a right triangle
3²+4²=5²
9+16=25
25=25
26) It is a right triangle
6²+8²=10²
36+64=100
100=100
27) Not a right triangle
5²+5²=10²
25+25=100
50=100
28) It is a right triangle
5²+12²=13²
25+144=169
169=169
Hope this helps :)

Thanks! But why report when the people can't see this question or even get the points since its from a while ago
step-by-step explanation:
The balloon assumes the shape of a sphere with a formula of the volume equal to V = 4/3 pi r^3 where r is the radius of the balloon. In this case, we are given with volume of 288 pi in^3. We just substitute the given volume such that the resulting radius that answers the problem is 6 inches.
Log4(x(x-3))=Log4(-7x+21)
Log4(X the power of two -3x)=Log4(-7x21)
X the power of two -3x=-7x+21
x=3,x=-7.
