If we round the two values (49 and 805) to numbers more easily worked with and use this product as an estimate we can see 3 165 is much to small
If we round 49 to 50 and 805 to 800 and observe the product of these two values we see an estimate of 40 000
This number is vastly larger than 3 165 so therefore the estimate shows that her answer is not reasonable
the blank is 162
since 81 and 81 are both perfect squares the middle term (blank) will be the product of their roots times 2
√81=9
√81 =9
9 x 9 x 2
= 162
If I was born in 1996 in 2017 i am 21 years old.
From year 1996 to year 2006 there are 10 years.
From year 2006 to year 2016 there are 10 years.
-> From year 1996 to year 2016 there are 10 + 10= 20 years.
And from year 2016 to year 2017 there is 1 year.
So, 10+10+1=21 years will pass from 1996 till 2017.
Answer:
8x+24
you multiply both the terms or l×w
