Which expression is equivalent to n2 + 26n + 88 for all values of n?

Y_Kistochka [10]

Answer:

(n + 4)(n+ 22)

Step-by-step explanation:

One way to determine which factored expression is accurate is by asking the question: "Which two numbers multiply to 88, but add to 26?" If you are having difficulty using this method, you can always try the guess-and-check method with a multiple choice question. This way involves multiplying the terms inside one set of parentheses with the terms inside the other set of parentheses.

Step #1: Multiply the first terms

(n + 4)(n + 22) ----> n x n = n²

Step #2: Multiply the inside terms

(n + 4)(n + 22) -----> 4 x n = 4n

Step #3: Multiply the outside terms

(n + 4)(n + 22) -----> n x 22 = 22n

Step #4: Multiply the last terms

(n + 4)(n + 22) -----> 4 x 22 = 88

Step #5: Write the new expanded equation and simplify

(n + 4)(n + 22) -----> n² + 4n + 22n + 88 -----> n² + 26n + 88

Suppose the area of a circle is 254.4696 square inches. Whats the radius of the circle (use pie=3.1416. A. 18 in. B. 81 in. C. 9

zalisa [80]

Answer:

The radius of the circle is 9 in

Choice C is correct

Step-by-step explanation:

254.4696 square inches. Whats the radius of the circle (use pie=3.1416.

The area of a circle with radius r is given as;

$A=\pi *r^{2}$

We substitute the given area and the value of pi given to solve for the radius;

$254.4696=3.1416*r^{2}\\\\r^{2}=\frac{254.4696}{3.1416}\\\\r^{2}=81\\\\r=\sqrt{81}=9\\\\r=9$

Which mathematical sentence most accurately expresses the information in the problem below? Crystal has 121 compact discs that s

ExtremeBDS [4]

Crystal has 121 compact discs. The total number of boxes required are 5.

<u>Solution:</u>

Given, Crystal has 121 compact discs that she wants to put into boxes.

Each of the boxes that she brought home holds 25 discs.

We have to find how many of these boxes will she need for all of her discs?

Now, we know that, number of boxes required $=\frac{\text {total number of discs}}{\text {capacity of one box}}=\frac{121}{25}=4.84=5$

Here we took 5 because 0.84 means that box with discs less than 25 still we require a box.

Hence, the total number of boxes required are 5.
