Answer:

38

Step-by-step:

f(-2)=3(-2)^2+(-2)+1                  g(-2)=-2(-2)-1

f(-2)=-6^2+(-2)+1                      g(-2)=4-1

f(-2)=36+(-2)+1                         g(-2)=3

f(-2)=34+1

f(-2)=35

f+g ------- 35+3 ------- 38

Which describes the cross section of a square prism that passes through vertices A, B, and C?
expeople1 [14]

Answer:

In triangle ABC one side equal 8\sqrt{2} and two sides equal 4\sqrt{13}

Step-by-step explanation:

We are given a prism whose base is square with sides 8 in and height 12 in.

If we take cross section through vertices A, B and C

We will get a cross section as triangle.

In triangle ABC, sides are AB, BC and AC

AB is diagonal of top square whose side 8 in.

AB=\sqrt{8^2+8^2}=8\sqrt{2}

AC is face diagonal of front face.

AC=\sqrt{8^2+12^2}=4\sqrt{13}

BC is face diagonal of right face.

BC=\sqrt{8^2+12^2}=4\sqrt{13}

AC=BC≠AB

Hence, In triangle ABC one side equal 8\sqrt{2} and two side equal 4\sqrt{13}
