Volume of the prism is given by:
Volume=length×width×height
but
V=<span>18x^3+5x^2-2x
V=x(18x^2+5x-2)
V=x(9x-2)(2x+1)
Hence the possible expression for the dimensions of the shipping box is x by (9x-2) by (2x+1)</span>
False, pictures are used in picture graphs or pictographs
Answer:
Step-by-step explanation:
The PR interval spans from the beginning of the p-wave to the beginning of the QRS complex, and it represents the time from the beginning of atrial depolarization to the beginning of ventricular depolarization. It's normally 0.12-0.20 seconds, which is three to five little boxes, since each little box is 0.04 seconds.Mar 24, 2020
