Your answer is 7g^4
Hope this helps!
You can see that the term 
appears in both equations. In this cases, we can leverage this peculiarity and subtract the two equations to get rid of the repeated term. So, if we subtract the first equation from the second, we have
Now that we know the value of 
, we can substitute in any of the equation to deduce the value of 
: if we use the first equation, for example, we have
This would mean that she has been in school for about 1,000 days. Thus, we need to figure out the amount of days she would have went to school within the week. This would normally be 5 days within the 7.
5/100 x 1000 is 714.28
When rounded to the nearest ten, it would end up at 710.
Answer:
It's divisible by 9
Step-by-step explanation:
Step-by-step explanation:
sec⁴A + tan⁴A = 1 + (2tan²A/cos²A)
LHS = sec⁴A + tan⁴A
= (sec²A)² + (tan²A)² {using formula of a²+b²)
= (sec²A-tan²A) + 2tan²A.sec²A
= 1 + {2tan²A.(1/cos²A)}
= 1 + (2tan²A/cos²A)
