The equation for the area of a circle is:
A=π*radius squared.
Since radius is half of the diameter.
Diameter/2=radius
Then plug it into the equation.
It’s -4 because when you take 4 out of 8 then you still have another 4 to take away to you go into the negatives and have the answer -4
(4x2 + 8)(4x2 – 8)
16(x2 + 2)(x2 – 2)
16x4 + 16x – 16x – 64

Answer:</h2>
<em>Question 1)</em>
5x
<em>Question 2) </em>
0.22a
<em>Question 3)</em>
8 + 6n
<em>Question 4)</em>
25
<em>Question 5) </em>
ab+c=14
<h2>
Step-by-step explanation:</h2>
<u>Ques 1)</u>
The product of 5 and x.
Product of two numbers means that it is obtained by multiplying them.
Hence, the expression so obtained is: 5x
<u>Ques 2)</u>
22% of a
It means that:
22%×a
Also, we know that:
22% =0.22
This means that:
22% of a=0.22×a
i.e.
22% of a=0.22a
<u>Ques 3)</u>
8 more than the product of 6 and n.
The product of 6 and n is given by: 6n
and 8 more than there product will be given by:
8+6n
<u>Ques 4)</u>
Evaluate: 30 − m/6 for m = 30
i.e. we put m=30 in the expression and get the resulting value.
i.e. we have:
30-m/6=30-(30/6)
i.e.
30-m/6=30-5
i.e.
30-m/6=25
<u>Ques 5)</u>
Evaluate ab + c for a= 2, b = 5, c = 4.
i.e. we will put the value of a,b and c in the given expression and find the value.
i.e.
2×5+4= 10+4
i.e.
ab+c=14
Answer:
3/4
