true because the square root is a number times itself and 4*4 is 16
Answer:
A is given by:
Step-by-step explanation:
The base length of the triangle is 4 units shorter than the height.
This means that
So
The expression for A in terms of h only was given above.
Answer:
GCF: 1
Step-by-step explanation:
Factors are numbers that can be evenly divided into another number. The greatest common factor of a set of numbers is the biggest number than can evenly divide into all the the numbers.
Let's list the factors of 60, 45 and 82
Factors of 60:
<u>1</u>, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Factors of 45:
<u>1</u>, 3, 5, 9, 15, 45
Factors of 82:
<u>1</u>, 2, 41, 82
The greatest factor that all 3 numbers share is 1.
Answer:
x = 14 is an extraneous solution
Step-by-step explanation:
Divide both sides by 4.
Square both sides.
Since we squared both sides, we much check for extraneous solutions because the process of squaring both sides can introduce extraneous solutions.
Check x = 14:
16 = -16 is a false statement, so the solution we found, x = 14, is an extraneous solution.
