What is the area of the equilateral triangle? Round to the nearest square centimeter. cm2 Equilateral triangle A B C with side length of eight centimeters

Answers

Answer 1

Answer: To calculate we use the equation for the area of a triangle. The area of a an equilateral triangle is expressed as: Area = (√3/4)a^2. Calculations are as follows:

Area = (√3/4)a^2
Area = (√3/4)8^2
Area = 16√3

Thus, the area of the equilateral triangle is about 28 cm^2

Rewrite 9(10 x) in distributive property

Answers

9(10+x)

To apply the distributive property, we need to multiply the number out of the parenthesis by each number inside.

9*10 = 90
9*x = 9x

9x + 90

Final answer: 9x + 90

9(10x)
= 9*10x
Explanation- you have to distribute the number outside the parenthesis with the numbers inside.

Answer:

y+5 = -3(x-2)

Step-by-step explanation:

We can use point slope form

y - y1 = m(x-x1)

We have a point and a slope

y - -5 = -3(x-2)

y+5 = -3(x-2)

Answer:

(5 + 2)(5-3)

What is a 33.33% increase followed by a 50% decrease?

Answers

33.33-50=-16.67%
hope that helped :)

If you let x = the original amount, then an increase of 33.33% would be represented by

x + (x × 33.33%)

Then if there was a decrease of 50%, you would now have

[x + (x ×33.33%)] × 50%

rewrite with decimal instead of %

[x + (x × .3333)] ÷ 2

The brackets and parentheses are important to tell the order in which to proceed.
