P=2l×2w
130=2l×2(l-9)
130=2l×2l-18
148=4l
37=l
w=l-9
w=37-9
w=28
The width is 28
It's difficult to answer this question without seeing the "indicated operations" the form a+bi is a standard form for imaginary numbers so you might see 2+3i, you can add this to say 4+5i by adding the real numbers (2+4) and the imaginary numbers (3+5) to get 6+8i. Hope that helps.
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.
