Answer: 14s^4 - 7s^2 + 15</h3>
====================================================
Work Shown:
(12s^4-6s^2+4s)+(6s^4-4s+27)-(4s^4+s^2+12)
12s^4-6s^2+4s+6s^4-4s+27-4s^4-s^2-12
(12s^4+6s^4-4s^4)+(-6s^2-s^2)+(4s-4s)+(27-12)
14s^4-7s^2+0s+15
14s^4-7s^2+15
Note: don't forget to distribute the negative to every term in the last parenthesis
Answer:
5+n
you have to distribute the “+” so you can drop the parenthesis. Then, you have 3+2+n. Add and you end up with 5+n
Answer:
-1
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 3-7)/(2- -2)
= (3-7)/(2+2)
= -4/4
= -1
Because the area of a square is the length of one side multiplied by itself, the area of this square would be 39.0625.
But, this is not the answer that is asked for. The problem gives you 3 significant digits, so we need to round 39.0625 to 3 significant digits. This would be 39.1 square feet.
