Answer: A. 7</h3>
Work Shown:
Replace every 'a' with 2, and replace every b with 3
a^2+b = 2^2 + 3 = 4 + 3 = 7
the square root of 42 is not a rational number, it is an irrational number
Answer:
1 inch = 0.3 miles
Step-by-step explanation:
We basically want to know how many miles in real life 1 inch on the map represents. We already know that 4 inches on the map corresponds to 1.2 miles in real life, but we need to find what 1 inch on the map corresponds to. Let's make a proportion:

Cross-multiply:
4x = 1.2
Divide by 4 from both sides:
x = 1.2/4 = 0.3
Thus, the scale is 1 inch = 0.3 miles.
Hope this helps!
Answer:
The answer to your question is F = 110.4 N
Step-by-step explanation:
Data
mass = 92 kg
acceleration = 1.2 m/s²
Force = ?
Process
To solve this problem use Newton's second law which states that the acceleration of an object is dependent upon two variables, the net force acting upon the body and the mass of the object.
Formula
F = ma
-Substitution
F = (92)(1.2)
-Result
F = 110.4 N
