Answer:
counfsed so can u write it in english ?
Step-by-step explanation:
Add the sides then what ever you got add that up with 9 yd
Answer: y= -5/2x+3
Explanation: by converting the equation into slope-intercept form you can use the slope and y-intercept given in the equation to graph.
Step-by-step:
5x= -2y+6
2y= -5x+6
Y= -5/2x+3
Slope= -5/2x
Y-intercept= 3
Length of each side = 11 cm
Solution:
Let a be the side of the square.
Side length of square = Side length of equilateral triangle
Therefore, side length of equilateral triangle = a
Perimeter of the square = Number of sides × side
= 4 × a
Perimeter of the square = 4a
Perimeter of the equilateral triangle = Number of sides × side
= 3 × a
Perimeter of the equilateral triangle = 3a
Sum of the perimeter of a square and equilateral triangle = 77 cm
⇒ 4a + 3a = 77
⇒ 7a = 77
Divide by 7 on both sides of the equation, we get
⇒ a = 11 cm
Length of each side = 11 cm.
