h = 6
l = 8
w = 6
surface area = 2 (wl +hl +hw) =
2( (6*8) +(6*8)+(6*6)) =
2(48 +48 +36)=
2(132)= 264 square inches
Answer:
2x²+2x+8
Step-by-step explanation:
4x²-2x+10-2x²+4x-2
=4x²-2x²-2x+4x+10-2
=2x²+2x+8
Answer:
I think its 7.5 but I might be wrong
Step-by-step explanation:
If cos(70) = 0.342
the cosine of the alternative angle of 70° will also give the same value
angle measure = 360 - 70 = 240°
cos (240) will also be 0.342
