Answer:
Step-by-step explanation:
(x^2 - 7x + 11)x^2 - 11 + 30
x^4 - 7x^3 + 11x^2 + 19
Answer:
x^4 − 7x^3 + 11x^2 + 19
Step-by-step explanation:
(x^2 − 7^x + 11)(x^2) − 11 + 30
Distribute:
=(x^2)(x^2)+(−7x)(x^2)+(11)(x^2) + −11 + 30
=x^4 + −7x^3 + 11x^2 + −11 + 30
Combine Like Terms:
=x^4 + −7x^3 + 11x^2 + −11 + 30
=(x^4) + (−7x^3) + (11x^2) + (−11 + 30)
=x^4 + −7x^3 + 11x^2 + 19

Answer:
(3, -4)
Step-by-step explanation:
Answer: (3;-4)
P.S. The coordinates should be written in square bracket, however I dont know how to type them.
Step-by-step explanation:
The coordinates conists of two numbers. The first number in the bracket (in our case number 3) indicates the position of the number along the x-axis. The second number in the bracket (in our case number -4) indicates the position of the number along the y-axis.

Background Information
Squares and Square Roots
A square is a 2-dimensional (2-D) shape with all four sides equal.
The total area the square covers is measured in square units.
To determine the side length of a square when given the area, the square root must be
determined.
A perfect square can be described as
Q a square with whole number sides (e.g., 1 × 1, 2 × 2, 3 × 3)
Q a number whose square root is an integer (e.g., 4 = 2 or –2)
A non-perfect square can be described as
Q a square with non-whole number sides (e.g., 1.2 × 1.2)
Q a number whose square root is not a whole number (e.g., 2)
Rounding is often used to determine the approximate square root of non-perfect
squares.

can you pls answer this
Answer:
D
Hey There!
To find the answer you have to add the frequencies of all of them and take the frequency of 3 people being in a car and divide that by the sum of all of the frequencies if that makes sense
37+98+40+25=200
The frequency of 3 people being in a car is 40
so we would do
[tex]\frac{40}{200}[/tex] which is equal to [tex]\frac{1}{5}[/tex]
Therefore D is your answer

Answer:
6) 9216π
8) 24
Step-by-step explanation:
6)
V= 2/3πr³
r = 48/2 = 24
V = 2/3π24³
V = 9216π
8)
V = 4/3πr³
2304π = 4/3πr³
r³= (2304π)/4/3π
r³= 1728
[tex]\sqrt[3]{r^3} =\sqrt[3]{1728}[/tex]
r = 12
D = 2r
D = 2 x 12 = 24

Shelley is making bows. Each bow is made using 9 inches of ribbon. Shelley needs to make 24 bows for a party. If the store sells ribbon by the foot, how many feet of ribbon does she need? answer choices: a= 18, b=19, c=23, d=216 .
Answer:
a. 18
Step-by-step explanation:
First you multiply 24 by 9 since each bow is 9 inches and she needs 24 bows.
After multiplying you should then end up with 216 in. Then convert 216 into feet which should give you 18.
