Answer:
SA of black base: 84 cm^2
SA of blue faces: 84 cm^2
SA of gold faces: 60.2 cm^2
SA of 1 ornament: 228.2 cm^2
SA of 100 ornaments: 22,820 cm^2
Step-by-step explanation:
SA of black base:
A = lw
A = 7(12)
A = 84 cm^2
SA of blue faces:
A = bh
(don't divide by 2 since there are 2 triangles)
A = 12(7)
A = 84 cm^2
SA of gold faces:
A = 7(8.6)
(don't divide by 2 since there are 2 triangles)
A = 60.2 cm^2
SA of 1 ornament:
Add #s in bold:
84 + 84 + 60.2 = 228.2 cm^2
SA of 100 ornaments:
Multiply SA of 1 ornament by 100:
228.2(100) = 22,820 cm^2

Step-by-step explanation:
becuase you subtract 11 from the x values to get the answer.
Answer:
X = -2
Step-by-step explanation:
4x + 2 = x3
Subtract 2 from both sides: 4x = x3 -2
Subtract x3 from both sides: 4x - 3x = -2
This leaves 1x = -2 which can also be written as x = -2
x = -2
