Answer:
3 metres
Step-by-step explanation:
Let the width of the pathway be x
Area: (9+2x)(4+2x)
36 + 8x + 18x + 4x²
4x² + 26x + 36
Increased area is 150:
4x² + 26x + 36 = 150
4x² + 26x - 114 = 0
2x² + 13x - 57 = 0
2x² + 19x - 6x - 57 = 0
x(2x + 19) - 3(2x + 19) = 0
(x - 3)(2x + 19) = 0
x = 3, x = -19/2
Answer:
u can use the hit and trial method for this
Answer:
y=x+1
Step-by-step explanation:
Answer: 6767/10000
Step-by-step explanation:
Just simplify it by its nearest tenth
Simply plug your y intercept in for b. You’ll get y= -3x+4. Draw a simple graph and plot your y coordinate first at 4. Since your slope is -3, then from your point 4 on the graph go down 3 spaces and to the right 1 space. Continue on until you get a line. Also, from 4, go up 3 spaces and to the left 1 space to complete the line.
