The answer would be 74,000. hope this helps
(3.7 x 10 to the 4th power) x 2 as well = 74,000
Answer:
Step-by-step explanation:
Yikes. This is quite a doozy, so pay attention. We will begin by factoring by grouping. Group the first 2 terms together into a set of parenthesis, and likewise with the last 2 terms:
and factor out what's common in each set of parenthesis:
. Now you can what's common is the (d + 3), so factor that out now:
BUT in that second set of parenthesis, we can still find things common in both terms, so we continue to factor that set of parenthesis, carrying with us the (d + 3):
BUT that second set of parenthesis is the difference of perfect squares, so we continue factoring, carrying with us all the other stuff we have already factored:
. That's completely factored, but it's not completely simplified. Notice we have 2 terms that are identical: (d + 3):
is the completely factored and simplified answer, choice 3)
Answer:
B. 4x^2=28x-112=0.
Step-by-step explanation:
Using area=length*width, 160=(2x+8)(2x+6).
Expanding, (2x+8)(2x+6)=4x^2+16x+12x+48.
Setting this equal to 160, 160=4x^2+28x+48, or 4x^2+28x-112=0.
45.87= 2.18 plus 300 is 345.87 hope this is correct if not im soooo sorry
