39¹/₅ or 39.2
The Problem:
The Process:
Here are some early expressions that need attention.
7 copies of the sum of 8 fifths and 4 mean that we have to multiply 7 with the sum of 8 fifths and 4. The term of "the product" is synonymous with multiplication.
Let us write an expression to match for '7 copies of the sum of 8 fifths and 4'.
Let us calculate the operation in parentheses at first.
And now we solve the full expression.
In mixed fraction:
In decimal:
Thus, the result is .
Keywords: what, 7 copies, the sum of, 8 fifths and 4, write an expression to match, and then evaluate, 39¹/₅ or 39.2, multiply, parentheses, in mixed fraction, decimal
25x2 + 16
25x2 − 64
25x2 + 64
Answer:
option (3) is correct.
Step-by-step explanation:
Given : factor 5x − 8
We have to choose an expression out of given option that is a difference of squares with a factor of 5x − 8
Using algebraic identity
a difference of squares is written mathematically as
Since one factor is 5x − 8
using identity stated above other factor has be 5x+8
Thus
On simplify , we get
Thus, option (3) is correct.

To find the area of a circle, use the formula A = πr^2. Identify the radius and substitute it into the formula to calculate the area. Round the answer to two decimal places if necessary.
To find the area of a circle, you can use the formula A = πr^2, where A represents the area and r represents the radius of the circle. Start by identifying the radius of the circle, which is the distance from the center to any point on the circumference. Once you have the radius, substitute its value into the formula and calculate the area. Make sure to round your answer to two decimal places if necessary. For example, if the radius of the circle is 5 units, the area would be A = 3.14 * 5^2 = 3.14 * 25 = 78.5 square units.

Answer: 200.96 cm
Step-by-step explanation:
Area of a circle:
Since we don't have the radius, we have to find it.
What you gave me is the diameter which is 16 (cm) I suppose.
Radius is half the diameter. Therefore we can divide the diameter by 2 to find the radius.
16/2=8cm
This is our radius.
Plug this into the area formula.
