Answer:
x = 8√5
Step-by-step explanation:
for right triangle
c^2 = a^2 + b^2
with c is the hypotenuse; a & b are the other sides
(4 + 16)^2 = (4√5)^2 + x^2
400 = 80 + x^2
x^2 = 320
x^2 = 64(5)
√x^2 = √64(√5)
x = 8√5

Answer:
Below.
Step-by-step explanation:
So 4-6 to 8-12.
4 can be devised by 12, and so can 6.
4:8 6:12
If we flip them over we can find the dilation.
so?
8:4 12:6
Each can be divided by 2.
So the factor if dilation is 2.
Answer:
1/8-7/8= -3/4
Step-by-step explanation:
1/8-7/8 is just like 7/8-1/8 but is the opposite
7/8-1/8=6/8 or 3/4
1/8+6/8=7/8
1/8-1/8=0
0-6/8= -6/8 or -3/4
