Answer 1 put all like terms then solve
hope it helps....
a) The value of the equation is A = ( x - 1 ) ( x² + 3 )
b) The value of the equation is B = ( x⁴ - 6x² + 10 ) ( x² - 4 )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
a)
The equation is A = x³ + 3x - x² - 3
On simplifying the equation , we get
A = x³ - x² + 3x - 3
A = x² ( x - 1 ) + 3 ( x - 1 )
On factorizing the equation , we get
A = ( x² + 3 ) ( x - 1 )
b)
The equation is B = ( x² - 3 )³ - ( 2 - x² )² + 3 ( x² - 3 )
On simplifying the equation , we get
B = ( x² - 3 )³ - ( x⁴ - 2x² - 2x² + 4 ) + 3 ( x² - 3 )
On further simplification , we get
B = ( x² - 3 )³ - x⁴ + 4x² - 4 + 3x² - 9
B = ( x² - 3 )³ - x⁴ + 7x² - 13
On factorizing the equation , we get
B = ( x - 2 ) ( x⁵ + 2x⁴ - 6x³ - 12x² + 10x + 20 )
B = ( x - 2 ) ( x + 2 ) ( x⁴ - 6x² + 10 )
And , on further simplification , we get
B = ( x² - 4 ) ( x⁴ - 6x² + 10 )
Hence , the equation is B = ( x² - 4 ) ( x⁴ - 6x² + 10 )

kattie and matt are both flying kites on a breezy day. the string of katies kite is extended 864 feet, and her kite makes a 38 angle of elevation with the ground. the string of matt's kite is extended 725 feet, and his kite makes a 40 angle of elevation with the ground. Whose kite is flying higher in the sky
Answer:
Kattie's kite is flying higherStep-by-step explanation:
Let the height of each kite be h.
The h is opposite to angle of elevation and the sting length is hypotenuse of the formed triangle.
Kattie's kite:
h/864 = sin 38°h = 864 sin 38°h = 532 ft (rounded)Matt's kite:
h/725 = sin 40°h = 725 sin 40°h = 466 ft (rounded)Kattie's kite is flying higher as 532 ft > 466 ft

Scott set up a volleyball net in his backyard. One of the poles, which forms a right angle with the 15) ground, is 7 feet high. To secure the pole, he attached a rope from the top of the pole to a stake 5 feet from the bottom of the pole. To the nearest tenth of a foot, find the length of the rope.
Answer:
8.6 feets
Step-by-step explanation:
From the scenario described :
The length of the rope, h is the hypotenus. From the data Given, we cannot obtain how far wthe bird will need to fly directly, we use Pythagoras rule to calculate the hypotenus of the triangle :
Hypotenus, h = sqrt(opposite² + adjacent²)
h = sqrt(7² + 5²)
h = sqrt(49 + 25)
h = sqrt(74)
h = 8.6 feet

Arnav is selling boxes of cookies.
He sells each box for $3.75.
His goal is to make more than $30.
How many boxes of cookies could he sell to reach his
goal?
Arnav needs to sell more than 8 boxes of cookies to reach his goal of making more than $30. Since the number of boxes must be a whole number, Arnav would need to sell at least 9 boxes of cookies to achieve his goal.
To determine how many boxes of cookies Arnav needs to sell to reach his goal of making more than $30, we can set up an inequality based on the selling price of each box.
Let's represent the number of boxes he sells as "x". Since each box is sold for $3.75, the total amount of money he will earn from selling "x" boxes is 3.75x.
To reach his goal of making more than $30, we can write the following inequality:
3.75x > 30
To solve for "x", we divide both sides of the inequality by 3.75:
x > 30 / 3.75
Simplifying the right side of the inequality, we get:
x > 8
To fulfil his objective of earning more than $30, Arnav must sell more than 8 boxes of cookies. Arnav would need to sell at least 9 boxes of cookies in order to reach his objective because the number of boxes must be a whole number.

the graph of y=x^2-4x is shown. name a zero of the function below
Answer:
0 and 4
Step-by-step explanation:
y = x^2 - 4x can be factored as follows: y = x(x - 4).
We find the zeros by setting this factored form equal to zero and solving for x:
x(x - 4) = 0, or x = 0, or x = 4.
The two zeros of this function are 0 and 4.
