There will be task cards that you will have to follow when you are out in space.
We are given a polynomial representing the area of a barnyard that is <span> 4x2 + 8x - 21. A rectangle's area is equal to length multiplied by the width which means we can use factoring.
</span><span> 4x2 + 8x - 21
(2x - 3 ) (2x + 7)
we can countercheck this to verify the polynomial.
In this case, the dimensions are </span> 2x - 3 and 2x + 7.
Answer:
Step-by-step explanation:
Answer:
4+2b=5+5b+20
<=> -3b=21
<=> b=-7
Step-by-step explanation:
<=> 4+2b=5+5b+5×4
<=> 4+2b=5+5b+20
<=> 2b-5b=5-4+20
<=> -3b=21
<=> b=-21/3
<=> b=-7
