X+8/4-x+5/4
The first term in the series is a positive "x", and the third one is a "-x". Since these are opposites, they cancel out
x+8/4-x+5/4
8/4+5/4
13/4
4 1/4
Answer:
None of the above
Step-by-step explanation:
1, 3, 5, 9, 15, 45 are multiple of 45

Divide both sides of the equation by 5.2

Move the constant to the right-hand side and change its sign

Add the decimals

You gotta round the be to 100,000
D. X=3cm
Since the triangles are similar, just set up a proportion to solve for x.
4/8=x/6. Then just cross multiply and solve from there.
