Answer:
42
Step-by-step explanation:
ABC + CBD = ABD
3x+33 + 5x+13 = 70
Combine like terms
8x +46 = 70
Subtract 46 from each side
8x+46-46 = 70-46
8x = 24
Divide each side by 8
8x/8 = 24/8
x=3
We want to find ABC
ABC = 3x+33 = 3*3 +33 = 9+33 = 42

Answer:
3. Option 2 (Perpendicular)
4. Option 3 (neither)
Step-by-step explanation:
3.
m1 = -7/8
Second equation: -8x + 7y = -21
7y = 8x - 21 y = (8/7)x - 3
m2 = 8/7
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-7/8)(8/7) = -1,
They are Perpendicular
4.
m1 = -1/4
Second equation: -2x + 8y = 6
8y = 2x + 6 y = (1/4)x + 3/4
m2 = 1/4
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-1/4)(1/4) = -1/16, not -1. They are not Perpendicular either. So, neither
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
