Answer:
24 cm
Step-by-step explanation:
Given: Picture of the star is made up of 4 unshaded equilateral triangles of equal area and a shaded square.
Area of the shaded region (square) = 
To find: the perimeter of the star
Solution:
Area of the shaded region (square) =
Area of square = 
As each equilateral triangle has side lengths that are the same as the side length of the square,
length of side of the star = 3 cm
Perimeter is the sum of lengths of the sides.
Perimeter of star = sum of 8 sides of the star
= 8 × 3 = 24 cm
Answer:
x = 6 ; Rewritten: 2x-3y-12=0 ; y=-4
Step-by-step explanation:
2x-3 multiply 0=12
x=6 ( that's the function)
Rewritten steps: 2x-3y=12 then move constant to the left by adding its opposite to both sides which gives you 2x-3y-12=12-12. After the sum of two opposites equals 0 which is 2x-3y-12=0
Y Intercept :
2x-3y=12 and to find y intercept, sub x = 0 ; to 2 multiply 0 -3y=12 and then you solve for the equation which is your answer.
The equation would be 2x + 5y = 11.
To find this, we first have to find the slope of the line. The slope formula is below.
m (slope) = (y2 - y1)/(x2 - x1)
In which (x1, y1) is the first point and (x2, y2) is the second. So we plug in to solve.
m = (3 - 1)/(-2 -3)
m = 2/-5
Now that we have the slope, we can use it along with a point to get the slope intercept form.
y = mx + b
3 = -2/5(-2) + b
3 = 4/5 + b
11/5 = b
Now that we have the equation of y = -2/5x + 11/5 we can manipulate it into standard form.
y = -2/5x + 11/5 -----> add 2/5x to both sides
2/5x + y = 11/5 ----> multiply both sides by 5
2x + 5y = 11
