3 0

Answer:

7x+5

Step-by-step explanation:

Perimeter is the sum of all four sides

So take the total perimeter and subtract the two sides we know.

18x+6-4x+4

14x+10 is what's left. But remember that's the length of the TWO other sides.

So, divide that in half and you get 7x+5

Write an equation to represent the following description "fourteen less than 8 times a number is -11
Serggg [28]

Answer:

(8 * x) -14 = -11

Step-by-step explanation:

* = multiply sign (i didnt want to put "x" as the multiply sign since "x" is already being used) ( mightve confused you with 2 "x"s in the parenthesis.

x = the number that is missing being multiplied by 8

I put "8" multiplied by "x" in parenthesis since you do parenthesis first in an equation.

A sector with a radius of 6 cm has a central angle measure of 4pi/9 (in radians). What is the area of the sector?
Usimov [2.4K]

Answer:

The area of the sector is 25.1327 cm²

Step-by-step explanation:

The area of a sector of circunference delimited by an angle in radians can be calculated by using the formula below:

area = (angle*r²)/2

area = [(4*pi/9)*(6)²]/2

area = [(4*pi/9)*36]/2

area = (144*pi/9)/2

area =  144*pi/18

area = 8*pi

area = 25.1327 cm²

The area of the sector is 25.1327 cm²
