Answer:
13.9 in
Step-by-step explanation:
Use the Pythagorean Theorem to answer this. Folding the paper along its diagonal produces two triangles; each one has shorter side 8.5 in and longer side 11 in. According to the Pyth. Thm., (8.5)^2 + 11^2 = 193.25, which results in the diagonal length √193.25, or approx. 13.9 in.
X-y = 4
X-8 = 2
Work the 2nd equation out, you get x=10
10-y = 4
Y=6
So x=10 and y= 6
See my comments . I think the answer might be D 25
14a= 2*7*a
28ab= 2^2*7*a*b
GCF (14a,28ab)= 2*7*a= 14a
The GCF of 14a and 28ab is 14a~
