Answer:
P=30
W=12
T=16
Step-by-step explanation:
There are 8 divisions on this number line between 0.08 and 0.40, so the width of each div. is 0.32/8, or 0.04.
Starting with 0.08, fill in the boxes as follows: 0.12, 0.16, 0.20, .... 0.28, 0.32, 0.63, ... , and 0.44.
Answer:
Width of 9cm and length of 17cm.
Step-by-step explanation:
To calculate an area of a rectangle, use the formula A=l*w. We know the length is 8cm longer than the width. So l = 8 + w. So the area is A= (8+w)*w.
We also know the area is 153. Substitute this value for A and solve.

To solve the quadratic, use the quadratic formula:

Here a=1, b=8 and c=-153.

Since w=9 or w=-17, substitute this value for w in l= 8+w to find l.
l = 8+9 = 17
or
l=8+-17 = -9
Since length cannot be positive, it must be l=17 and w=9.
