The answer would be 56n^2 + 19n - 15
Multiply 8n with 7n to get 56n^2, then multiple 8n with 5 and you get 40n, then multiple -3 with 7n to get -21n, then -3 times 5 which gives you -15. Simplify and that is the answer you would get.
Answer:
I think its B 252yd^2
Step-by-step explanation:
i got 254 so it might be 252
You said that (xy) = 16, and (x+y) = 4 .
From the second equation you can get [ x = 4 - y ],
then substitude that for 'x' in the first equation, and
finally, rearrange the first equation to read
<u>x² - 4x + 16 = 0</u>
Don't even try to factor that quadratic equation. Go straight
to the quadratic formula, and the two solutions you find are ...
<em>x = 2 + i 2√3</em>
and
<em>x = 2 - i 2√3</em> .
Those are the two number that do what you want.
There are no <u>real</u> numbers that can do it.
It will take her 34 weeks. I got this answer because 10% of $450 is $45. Since she borrowed $1500, you divide $1500 by $45. You get 33.333... Since you earn per week, that rounds up to 34 weeks.
