Answer: x + 100
Step-by-step explanation:
From the question, we are told that Bobbie has 100 more followers than Debora and x is used to represent the number of followers that Debora has.
The expression that shows the number of followers Bobbie has will be the number of followers that Debora has plus 100. This will be :
= x + 100
For this case we have an exponential expression of the form:
We can rewrite the exponential expression using power properties.
We have then:
From here, we take the square root of 36.
We have then:
Answer:
The exponential function is given by:
Answer:
To get the area of a parallelogram
Step-by-step explanation:
A=bh is the formula for an area so option D is definitely wrong.
The formula for the area of a triangle is .
The formula for the area of a circle is πr²
The formula for the area of a parallelogram is A=bh
A=bh is the formula for the area of a parallelogram.
