Answer:
B
Step-by-step explanation:
You are combining like terms.
1.) find all of the #x³ and there is only one and that is -x³ so that limits the problem to B or D.
2.) now you find all of the #x² and there are three of them being 10x², -x², and 4x². Now that you have identified them you will add them together to get a sum of 13x²
you don't have to do anymore of the question because D does not have 13x² so it is B.
Its B! Plz give me brainlist :)
To do this, find the surface area of each two-dimensional shape.
The two triangles have a combined area of 24.
The two rectangles have a combined area of 70.
The center rectangle has an area of 42.
Add them together to get 136 as your surface area.
Answer:
let the unknown rational number be X.
26/X=39
X=39/26
X=3/2
