For this you will use a^2+b^2=c^2
So 21 would be your c^2 and 9 your b^2 so now it'll look like this
A^2+9^2=21^2
A^2+81=441
next you move the 81 over so you subtract 81 from both sides and you're left with
A^2=360
after you get the square root so a=18.9
and rounded you're answer would be B. 19 feet
Hope this helped :)
Answer:
$1350
Step-by-step explanation:
5% of 1000 is 50
50x7 is 350
1000+350=1350
It is rational because the square root of 25 is 5.
<u>Your answer is 28x^2-37x+12</u>
<u>1) Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd</u>
28x^2-21x-16x+12
<u>2) Collect like terms</u>
28x^2+(-21-16x)+12
<u>3) Simplify</u>
28x^2-37x+12
