Answer
4(y - 6)
Explanation
The difference of y and 6 can mathematically be represented as y - 6.
Therefore, four times the difference of y and six will be 4(y - 6).
Answer:
108
Step-by-step explanation:
cross multiply fractions:
12/72 = 18/x
x = 108
A. The figure is a triangular pyramid. You can findits surface area by adding up the area of the three faces of the triangle and the area of the base. A derived formula also is used where the SA is equal to 12 times the perimeter of base times the slant height, added to that is the area of the base. The area of the square base is s^2. Its perimeter is 4s.
SA of Pyramid = 12*P*l + s^2
SA of Pyramid = 12*4s*l + 16^2
SA of Pyramid = 12*4(16)*(17) + (16)^2
SA of Pyramid = 11,008 square inches
b.) The formula for the SA of a cone is:
SA of cone = πr[r+√(h^2+r^2)]
SA of cone = π(3)[(3+√(8^2+3^2)]
SA of cone = 108.8 square inches
Answer:
8 (7 + 4) = 56 + 32
Step-by-step explanation:
Greatest common factor of 56 & 32 is 8
8 x 7 = 56
8 x 4 = 32
8 (7 + 4 )
