What is the coefficient of the c-term of the algebraic expression 14a - 72r - c - 34d? A) -34
natima [27]
When the coefficient of a term is 1 or -1, we don't write it, we just use the + or - sign. The coefficient of the c term is -1, because of the - sign in front of it and the lack of written coefficient. Any questions?

Answer:

  D.  105 ft²

Step-by-step explanation:

The total surface area is the sum of the base area and the triangular face areas.

Area of base:

  A = s²

  A = (7 ft)² = 49 ft²

Area of 4 triangles:

  A = 4(1/2)bh

  A = 2(7 ft)(4 ft) = 56 ft²

Total surface area:

  base area + triangle area = 49 ft² +56 ft² = 105 ft²
