Answer: b)

Step-by-step explanation:

You can rule out A) and C), because you have to find area (no adding.)

To do this problem, you can individually multiply the estimated hieght and

width by 3 and then multiply together.

This is because there are 3 walls that each are 9 3/4 tall and 14 1/4 wide. To find total height and width, multiply by 3. Then find total area (lxw)

9 3/4 rounds to 10

14 1/4 rounds to 14

= 3 (10) x 3 (14)

D) is incorrect because you have to multiply each number by 3. (Or you can multiply by 6)

It is B)

Alan multiplies a 4-digit number by 36. How can you tell the

mafiozo [28]

The number of partial products Alan will have when he multiplies a 4-digit number by 36 is; 8 partial products.

First, we must establish that a 4-digit number will have 4 place values namely;

Thousands
Hundreds
Tens
Ones.

And since, 36 has 2 place values;

We can conclude that the number of partial products that Alan wil have is; 2× 4 = 8.

The polynomial 3x2 is a with a degree of .

ZanzabumX [31]

To determine the degree of a polynomial, you look at every term:

if the term involves only one variable, the degree of that term is the exponent of the variable
if the term involves more than one variable, the degree of that term is the sum of the exponents of the variables.

So, for example, the degree of $7x^{55}$ is 55, while the degree of $xy^2z^4$ is $1+2+4 = 7$

Finally, the term of the degree of the polynomial is the highest degree among its terms.

So, $3x^2$ is a degree 2 polynomial (although it only has one term)

similarly, $x^2y + 3xy^2 + 1$ is a degree 3 polynomial: the first two terms have degree 3, because they have exponents 2 and 1.

(05.05)Polygon ABCD has the following vertices: A(−5, 4), B(1, 4), C(6, −4), and D(−5, −4) Calculate the area of the polygon.

ella [17]

The first thing you should do is draw the points in the Cartesian plane and then join them to find the polygon.
The searched polygon can be seen in the attached image.
The area of the polygon will be the area of the square plus the area of the triangle.
At = (6) * (8) + (1/2) * (5) * (8) = 68
At = 68
answer
the area of the polygon is 68units ^ 2
