Answer:
b = 3, which is an extraneous solution because if we replace b = 3 in the equation, we must be 5/0 and 30/0, and there is division by 0.
Step-by-step explanation:
The minus common multiply must be (b-3)*(b+3) = b² - 9
7b - 21 + 5b + 15 = 10b
2b = 6
b = 3
Which is an extraneous solution because if we replace b = 3 in the equation, we must be 5/0 and 30/0, and there is division by 0. So this solution is invalid.

Answer:
the scale drawing is larger
Step-by-step explanation:
The scale tells you that ...
17 cm on the scale drawing represent 1 mm on the actual object.

Step-by-step explanation:
hsq=psq+bsq
csq=48sq+14sq
csq=2304+196
c=50cm
where,
sq=square
