2to the power of 3 parentheses 30 divided by 5 plus 9

120

Step-by-step explanation:

Simplify the following:

2^3 (30/5 + 9)

The gcd of 30 and 5 is 5, so 30/5 = (5×6)/(5×1) = 5/5×6 = 6:

2^3 (6 + 9)

6 + 9 = 15:

2^3×15

2^3 = 2×2^2:

2×2^2×15

2^2 = 4:

2×4×15

2×4 = 8:

8×15

8×15 = 120:

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
