Answer:
-1 is the first answer of question
-8 is the answer of second question
Lets say the width is W and the length is L,
So its W * L = 196
but we also know W*4 = L
which means we can substitute L for W * 4 so our equation will be
W*W*4 = 196
W*W = 49
W= 7
Answer: I am glad I get to help you today. So, I hope this helps you. And Have a great day!!!!!
Step-by-step explanation:
<span>Note that -6.8 = -1*6.8. Therefore (-6.8)2 = (-1)*6.8*2. The product of 6.8*2 is 13.6. Hence (-6.8)2 = (-1)*13.6 = -13.6.</span>
Answer:
-10.2n - 1
Step-by-step explanation:
We have two expressions in variable n and we have to add the two expressions.
An important thing to note is that only like terms can be added. i.e. the term with "n" can only be added or subtracted to the term with "n". Similarly a constant can only be added or subtracted to a constant.
Thus, the two given expressions add up to -10.2n - 1
