Answer: a2 + 152 = 362
Step-by-step explanation:
No solution / no x
D=b^2-4*a*c -> D=-4^2-4*1*21 -> D=-28 -> D<0, no solution

Answer: Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area
Answer:
Step-by-step explanation:
Area =6*6sin56/2=18sin56
Area=5.7*6sinx/2=5.7*3 sin x
18sin56=3*5.7sinx
sinx=6sin56/5.7=1.05 *sin 56
Please do the calculation because now I can not do.
I hope it will help you !
