Which of the following equations uses the commutative property of addition to rewrite 1/3 + 2/5?
luda_lava [24]

The commutative property states that you can invert the order of the terms of a sum:

a+b=b+a

So, if you start with

\dfrac{1}{3}+\dfrac{2}{5}

Applying the commutative property you'll get

\dfrac{2}{5}+\dfrac{1}{3}

DedPeter [7]

Answer:

The surface area is equal to 390\ in^{2}

The surface area of the triangular pyramid is equal to the area of its four triangular faces

so

In this problem

SA=4[\frac{1}{2}(b)(h)]

we have

b=15\ in

h=13\ in

substitute the values

SA=4[\frac{1}{2}(15)(13)]=390\ in^{2}
