No
X would have to equal 6 or greater as if x was 5
5+3 is the same as 8
B. One solution (I think)
SA pyramid+SA rectangular prism= total SA
Total SA= Area of the base+ area of the four rectangles+area of four triangles
Total SA= length^2+length*width*4+1/2(slant height)(length)*4
length=12, width=8, slant height=10
Total SA= (12)^2+4(1/2*12*10) +4(12*8)=768cm^2
so C is correct.
Answer:
-4x^2+9x
Step-by-step explanation:
Adding boh gives
(f+g)(x)=-2x^2+(-2x^2+9x)
=-2x^2-2x^2+9x
=-4x^2+9x
