16x-15-9x=13, you would combine 16x and -9x to make 7x, so 7x-15=13, then you would add 15 to 13, and your new equation would be 7x=28. THen divide 28 by7 and your answer is 4

Fantom [35]

Answer:

She should have used One-half (9.4) (11.9) to represent the area of a single triangle

Step-by-step explanation:

The pyramid is composed by 4 triangles and 1 square

area of the square: base² = 9.4²

area of each triangle = 1/2*base*height = 1/2*9.4*11.9

surface area of the pyramid = 4*area of each triangle + area of the square = 4*(1/2*9.4*11.9) + 9.4²
