(-5x² - 2x + 4) + (8x² - x - 1) + (x + 2)(x - 5)
.The polynomial simplifies to an expression that is a____
A.quadratic
B.liner
C.constany
A.trinomial
B.binomial
C.monomial
with a degree of____
A.1
B.2
C.0
Solution:
A polynomial is an expression involving operations of addition, subtraction, multiplication, exponents which consists of variables and their coefficient. A trinomial is a polynomial consisting of three terms, while a binomial consist of two terms and a monomial consist of one term.
The degree of a polynomial is the highest degree of any of the terms of the polynomial. If it has a degree of 0 it is a constant, a degree of 1 it is linear while for a degree of 2 it is quadratic.
(-5x² - 2x + 4) + (8x² - x - 1) + (x + 2)(x - 5)
= (-5x² - 2x + 4) + (8x² - x - 1) + (x² -5x + 2x - 10)
= (-5x² - 2x + 4) + (8x² - x - 1) + (x² - 3x - 10)
= (-5x² + 8x² + x² - 2x - x - 3x + 4 - 1 - 10)
= 4x² - 6x - 7
Therefore:
.The polynomial simplifies to an expression that is a quadratic trinomial of degree 2.

A 17 -ft ladder leans against a building so that the angle between the ground and the ladder is 79 .
Answer:
3.24 feet
Step-by-step explanation:
A 17 -ft ladder leans against a building so that the angle between the ground and the ladder is 79 . Find the distance between the building and the ladder
We solve the above question using the Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = x feet
Hypotenuse = 17 ft
The angle = 79°
Hence,
cos 79 = x/17
Cross Multiply
x = cos 79 × 17
x = 3.2437529214.feet
Approximately = 3.24 feet
Therefore, the distance between the ladder and the building = 3.24 feet

Posts are 4 1/4 feet in length. Posts must be installed 7/8 feet below ground level, What will be the height of fence?
Answer:
Step-by-step explanation:
4 1/4x7/8
I think 119/32
The height of fence will be "[tex]\frac{41}{8}[/tex]".
According to the question,
Length of posts,
= [tex]4\frac{1}{4} \ feet[/tex]
Length of posts below ground level,
= [tex]\frac{7}{8} \ feet[/tex]
Now,
→ The height of the fence will be:
= [tex]4\frac{1}{4} +\frac{7}{8}[/tex]
= [tex]\frac{17}{4}+\frac{7}{8}[/tex]
= [tex]\frac{34}{8}+\frac{7}{8}[/tex]
= [tex]\frac{34+7}{8}[/tex]
= [tex]\frac{41}{8}[/tex]
Thus the above is the right answer.

3x+9=36
Show your steps
Answer:
x=9
Step-by-step explanation:
3x+9=36
subtract 9 from both sides
3x=27
divide by 3 on both sides
x=9
The solution to the equation 3x + 9 = 36 is x = 9.
To solve the equation 3x + 9 = 36, we'll perform the necessary steps to isolate the variable x on one side of the equation.
Given equation:
3x + 9 = 36
First, we'll subtract 9 from both sides to eliminate the +9 term on the left side:
3x + 9 - 9 = 36 - 9
3x = 27
Next, to isolate the variable x, we divide both sides by 3:
(3x)/3 = 27/3
x = 9
Therefore, the solution to the equation 3x + 9 = 36 is x = 9.
In this equation, we start with an expression involving the variable x and a constant term. By performing algebraic operations, we manipulate the equation to have x on one side and the constant value on the other side. This isolates the variable and provides us with a specific value for x that satisfies the equation. In this case, the value of x is determined to be 9, which can be verified by substituting it back into the original equation to see if it holds true.

A number is multiplied by 6, and the result is 48.6.
Answer:
8.1
Step-by-step explanation:
We denote the number as x.
6 * x = 48.6
We can divide both sides by 6 to get,
x = 8.1
Answer:
8.1
Step-by-step explanation:
Let the unknown number be n. Translating this statement into symbols, we get:
6n = 48.6
Solving for n by dividing both sides by 6, we get n = 8.1
The number is 8.1
