Im sorry i messed up its a and ....
The simplified expression is: -14s⁴-2s²+3s-3.
First group all the like terms together.
(-8s⁴)+(-6s⁴)=-14s
-2s
7s+(-4s)=3s
-3
Then put the expression back together, starting with the term that has the largest exponent, then working your way down. You would then get: -14s⁴-2s²+3s-3.
Answer: 104
Step-by-step explanation:
It is a full circle
Circle = 360
We have 126 and 26 so
360 - (126+26) = 208
Since the a's are opposite thet means they are equal ( I forgot the law name)
208 divided by 2
104
Answer with explanation:
Pyramid and Plane both are three dimensional shapes.
Pyramid is a three dimensional shape having base any polygon and other faces as triangles.
The base of pyramid is horizontal.
1. If lower base is a Square,or rectangle or any other parallelogram
And, then , plane cuts the pyramid vertically
It will be also, a three dimensional shape ,resembling a triangular cross section in three dimension.
Triangle is appropriate choice.
1) you can expand the brackets, simplify, set the equation = 0 and then do a double bracket factorisation.
2)
therefore Josh's solution is wrong asx = 7 and x= -1
