A regular hexagon has an apothem measuring 14 cm and an approximate perimeter of 96 cm.
WINSTONCH [101]
Given:
hexagon
apothem of the hexagon: 14 cm
perimeter of the hexagon: 96 cm

Area of the hexagon = [(3√3) / 2] a²     ; where a is the measure of the side

hexagon has 6 sides.

Perimeter = 6a
96 cm = 6a
96 cm / 6 = a
16 = a

We can also use the area of a triangle to approximate the area of the hexagon. There are 6 triangles in the hexagon .

Area of a triangle = (height * base) / 2
A = (14 cm * 16 cm) / 2
A = 224 / 2 
A = 112 cm²

112 cm²  * 6 triangles = 672 cm²

What is -4/5+ 7/15 when you simplify ?
photoshop1234 [79]

Answer: -\frac{1}{3}

Step-by-step explanation:

When you add fractions with different denominators, you need to find the Least common denominator (LCD):

Descompose the denominators (5 and 15) into its prime factors and then choose the commons and non-commons with the highest exponents:

5=5*1\\15=3*5\\\\LCD=5*3*1=15

Divide the LCD by each original denominator of each fraction and multiply the result by each original numerator of each fraction. After this, you can add the numerators and reduce the fraction.

Then:

-\frac{4}{5}+\frac{7}{15}=\frac{-(4)(3)+7(1)}{15}=\frac{-12+7}{15}=\frac{-5}{15}=-\frac{1}{3}
