Gotta be red like mine. Right????
Answer:
128 + 96√3 or 294.28 unit^3 to the nearest hundredth.
Step-by-step explanation:
The surface area of one of the pyramids = area of the square base + area of the 4 equilateral triangles
= 8^2 + 4 * 1/2 * 8 * 4√3
= 64 + 64√3.
So the area of the new solid = 2(64 + 64√3) - area of 2 triangles
= 2(64 + 64√3) - 32√3
= 128 + 128√3 - 32√3
= 128 + 96√3.
Y-(-5)/x-(-18)=-2/9
9y+45=-2x-36
9y=-2x-36-45
y=-2/9x-9
Answer:
0
Step-by-step explanation:
because it has no slope
B + 4(b) - (8) ➡0
~Add the number 8 to each of the sides of the equations that you're working with ⬇ ~
5(b) - 8 ➡0
~Now, you have to divide 5 by each of the sides to the equation⬇~
B = 8 ÷ 5 = 1.6
So,your answer might be 1.6
