If the x between 5 and 2 is a letter then the answer is -21
If it’s a multiplication sign then it’s 19
Use photo math shows step by step! So much easier than relying on other people!
I think what you are wanting id 0.1 is that rounded to one significant figure
Answer:
x = 14.4
Step-by-step explanation:
Similar means that the figures are proportional to each other. Because of this, we can form a problem. 
(the short side lengths) = 
(the long side lengths). Now we can solve this by cross-multiplying. If we multiply 9 · 8 we get 72, and 5 · x is 5x. 72 = 5x. Now divide both sides by 5. 72 ÷ 5 = 14.4. Therefore, x should be equal to 14.4. Does this make sense?
