Answer:
Step-by-step explanation:
The first term must have one number before decimal point 
the second term (factor) must be 10 having some power.
example;
5.0 ×10³
7.002×10^41
 
        
             
        
        
        
Answer:
Step-by-step explanation:
To solve this correctly, you need to make sure to distribute the negative onto both terms in the second parentheses. 
So fully expanded, the problem would be:
2y² + 8y -7 + 3y - 3 = ?
You can easily rearrange the terms, or just do it in your head!
It would become:
2y² + 8y +3y -7 -3
= 2y² + 11y -10
Make sure you keep the terms with different variables separate! I hope this is helpful!
 
        
             
        
        
        
Answer:
The answer is 70 units2
Step-by-step explanation:
D = dx
2 + dy
2
W = (5-10)
2 + (10-5)
2
W = (5)
2 + (5)
2 = 7.071
L = (5-12)
2 + (10-17)
2
L = (7)
2 + (7)
2 = 9.899
A = LxW = (9.899)(7.071) = 69.9958 units
