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
1 1/2 is the correct answer
Answer:
<h2>Option B is the right answer.</h2>
Step-by-step explanation:
are two irrational numbers, that is, they can not be shown as the fraction of two integers.
is also a irrational number, since it also can not be represented as the fraction of integers.
Hence, the given expression represent the product of two irrational number and is equivalent to an irrational number.
3(2y-3)=27
6y-9=27
6y=36
y=6
