Answer:
x = 10
Step-by-step explanation:
Call the shortest side = x
Therefore the perimeter is x + (x+1) + (x+ 1) = P
The perimeter of the square is 4*(x - 2)
So these two conditions are equal
x + (x+1) + (x + 1) = 4*(x - 2) Remove the brackets on both sides.
x + x + 1 + x + 1 = 4x - 8 Combine the terms on the left
3x + 2 = 4x - 8 Add 8 to both sides
3x + 2 + 8 = 4x - 8+ 8 Combine
3x + 10 = 4x Subtract 3x
3x-3x + 10 = 4x - 3x Combine
10 = x
Answer: y-intercept: (0, -0.7) and x-intercept: (-1.2, 0)
Recall: The coordinate of a point is always written as (x,y).
Look to the x- and y-axis and see where there's a point that's exactly on it; that'll be your x- and y-intercept.
The point (0, -0.7) is on the y-axis, so that's your y-intercept. The point (-1.2, 0) is on the x-axis, so that's your x-intercept.

Answer:
12 cm
Step-by-step explanation:
The formula for the area of a trapezoid is written as:
1/2(b1 + b2)h
h = height = 16 cm
b1 = Length of one parallel side = 9cm
b2 = Length of second parallel side = ?
Area of trapezoid = 168cm²
The formula to find the length of the second parallel side =
b2 = 2A/h - b1
b2 = 2 × 168/16 - 9
b2 = 336/16 - 9
b2 = 21 - 9
b2 = 12cm
Therefore, the length of the second parallel side is 12 cm
Yes it is , hope it helped
