I think it’s mean sorry if I’m wrong
Just write any 4 numbers for x
x=-1,0,1,2
-2(-1)=2
in the graph (-1,2)
-2(0)=0
(0,0)
-2(1)=-2
(1,-2)
-2(2)=4
(2,4)
The new cube will have 7 surfaces: 4 equal square sides, 2 square surface with a hole, and one hole surface.
Area (A1) of 4 square surfaces = 4*L*W = 4*4*4 = 64 cm^2
Area (A2) of the two surfaces wit a hole = 2(L*W - 2πd^2/4) = 2(4*4-π*2^2/4) = 25.72 cm^2
Area (A3) of the hole = πD*W = π*2*4 = 25.13 cm^2
Total surface area, A = A1+A2+A3 = 64+25.72+25.13 = 114.85 cm^2
I would have to say skewed right
-2x • 3x = -6x2 (the 2 is an exponent)
4y • -7y = -28y2 (the 2 is an exponent)
-2x • -7y = 14xy
4y • 3x = 12xy
14xy + 12xy = 26xy
—> -6x2(expo) - 28y2(expo) + 26xy
Check the answer again just to be sure, it’s been a while since I’ve had algebra!
