Answer:

The value of the given expression is -878.08.

Step-by-step explanation:

Here, the given question is INCOMPLETE.

The complete question is:

Evaluate the expression for a = 4, b = -5, and c = -7. 4a^2b^{-2}c^3

Here, substitute the vale of a  = 4, b = -5 and c = -7, we get:

4a^2b^{-2}c^3  = (\frac{4a^2c^3}{b^2})  =  (\frac{4(4)^2(-7)^3}{(-5)^2})\\= (\frac{64 \times 343}{25})   =\frac{21,952}{25} =   878.08\\\implies 4a^2b^{-2}c^3 =   878.08 ( a = 4, b = -5 ,c = -7)

Hence, the value of the given expression is -878.08.

Answer:

\frac{x}{6}  =  \frac{10}{9}  \\   \therefore \: 9 \times x = 6 \times 10 \\ \therefore \:9x = 60 \\ \therefore \:x =  \frac{60}{9}  \\ \therefore \:x =  \frac{20}{3}  \\   \:  \:  \:  \:  \:  \: \huge \red{ \boxed{\therefore \:x =  6\frac{2}{3} }}

the perimeters of a rectangle and an equilateral triangle are equal. what is the equation for this scenario?rectangle’s perimete
djyliett [7]

The total length of a boundary defines the perimeter of an equilateral triangle.

<h3>What is the Perimeter of an Equilateral Triangle?</h3>
  • The total of the three sides makes up the perimeter of an equilateral triangle.
  • The following fundamental characteristics define a triangle as being equilateral:
  1. The three sides are equal.
  2. There is a 60° angle between all three.
  • The sides of the triangle PQ = QR = RP in the following illustration have equal lengths.
  • The triangle's angles are also equal in addition to this. An equilateral triangle is what this is.
  • An equilateral triangle's perimeter is now equal to 3a, where a denotes one of the triangle's sides.
  • Perimeter of Equilateral Triangle Formula : P = 3a, where 'a' stands for one of the triangle's sides, is a simple formula for calculating an equilateral triangle's perimeter. An equilateral triangle has three equal sides, hence the sum is equal to three equal sides, or 3a.
  • Additional equilateral triangle formulas include the following: When we need to determine a triangle's height from its sides, we can apply the following formula: Equilateral Triangle Height = (3a)/2
  • The semi-perimeter of an equilateral triangle must be determined in a few situations. Half of a perimeter, or semi-perimeter, is equal to 3a/2, which is derived using the formula semi-perimeter = (a + a + a)/2.
