Answer: Option 'a' is correct
Step-by-step explanation:
Since we have given that
Length of parallelogram =17.25 mm
Width of parallelogram =5.065 mm
As we know the formula for " Area of parallelogram"
Area of parallelogram is given by

Hence, option 'a' is correct .
Answer: 98.1
Step-by-step explanation:
Given: mass= 970 gm
Time = 14 min
rate of decay= 15.1% per minute.
Now, computing to get amount of element remaining after 14 minutes.
Formula; Element remaining=
Element remaining=
⇒ Element remaining=
⇒ Element remaining= ≅ 98.1 (nearest 10th of a gram)
∴ 98.1 element is still remaining after 14 minutes.
Answer:
I would think it is supplementary.
Step-by-step explanation:
If 2 angles equal 180 degrees, then they are supplementary.
Answer: (x + 3)(x - 4)
Step-by-Step Solution:
We need to Factorize the given Quadratic Polynomial by using Splitting the Middle Term Method.
= x^2 - x - 12
= x^2 - 4x + 3x - 12
= x(x - 4) + 3(x - 4)
=> (x + 3)(x - 4)
