Answer:
a = 4
Step-by-step explanation:
STEP 1) 4a - 16 = 4 • (a - 4)
The probability would be 9/12 or 3/4 in the lowest form
Answer:

Step-by-step explanation:

Multiply the numbers: 

Answer:
√20 units.
Step-by-step explanation:
Please see attached photo for diagram.
The other leg of the triangle is x as shown in the attached photo.
Using the pythagoras theory, we can obtain the the value of x as follow:
x² = 4² + 2²
x² = 16 + 4
x² = 20
Take the square root of both side.
x = √20 units
Therefore, the value of the other leg x of the triangle is √20 units
The quick and easy answer is 3/100
