What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ (5z² + 3z + 2)²
Now, We get;
⇒ (5z² + 3z + 2)²
⇒ 25z⁴ + 9z² + 4 + 30z³ + 12z + 20z²
⇒ 25z⁴ + 30z³ + 29z² + 12z + 4
Thus, The value of equivalent expression is,
⇒ 25z⁴ + 30z³ + 29z² + 12z + 4

Step-by-step explanation:
5.[tex] - 8(5 + 4x) = - 232[/tex]
[tex] - 40 - 32x = - 232 \\ - 32x = - 232 + 40 \\ - 32x = - 192 \\ \frac{ - 32x}{ - 32} = \frac{ - 192}{ - 32} \\ \\ \huge x = 6[/tex]

5/6x- 1/5x =19
5/6x- 1/5x =19
?/30x=19
Answer:
x = 30
Step-by-step explanation:
5/6x- 1/5x =19
Get a common denominator of 30
5/6x * 5/5 - 1/5x * 6/6 = 19
25/30x - 6/30x = 19
19/30x = 19
Multiply each side by 30/19
19/30x * 30/19 = 30/19 * 19
x = 30
Answer:
5/6x- 1/5x =19
5/6x- 1/5x =19
?/30x=19
19/30x = 19
x = 19 / 19/30
x = 19 * 30/19
x = 30

Tina solved an equation incorrectly, as shown below:
Step 1: 8x = 24
Step 2: x = 24 − 8
Step 3: x = 16
Which statement best explains why Step 2 is incorrect in Tina's solution?
Answer:
Step 2 should be division, not subtraction.
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
8x = 24
Step 2: Solve for x
Divide both sides by 8: x = 3We see that 8x is actually 8 times x. Therefore, we would need to use the Division Property of Equality to isolate x and get our answer.

Answer:
The correct option is A
Step-by-step explanation:
Since (1, 3) are the solutions to the function g(x), then
g(x) = (x – 1)(x – 3) = x² –3x – x + 3 = x² – 4x + 3
We know that f(x) is on the same plane and f(1) = 1.
Let's take g(1) = (1 – 1)(1 – 3) = 0
Therefore, when x = 1; f = 1 and g = 0. Hence
g(1) = f(1) – 1
In order words, g(x) could be f(x) – 1.
The correct option is A

Question is
"Antonio knows that a antenna that is 16 meters tall casts a shadow that is 30 meters long. He wants to calculate the height of a nearby utility pole. If its shadow is 45 meters long, how tall is the utility pole?"
Write your answer as a whole number or a decimal. Do not round.
SHOW ME YOUR WORK IF POSSIBLE
When the shadow is 45 meters long, it should be noted that the height of the utility pole will be 24 meters.
How to illustrate the information?It should be noted that from the information, Antonio knows that a antenna that is 16 meters tall casts a shadow that is 30 meters long and he wants to calculate the height of a nearby pole.
Let the height be x.
Therefore, this will be illustrated as:
16 / 30 = x / 45
Cross multiply.
30 × x = 45 × 16
x = (45 × 16) / 30
= 24
Therefore, when the shadow is 45 meters long, it should be noted that the height of the utility pole will be 24 meters.

find all values of x in the interval [0, 2????] that satisfy the inequality. (enter your answer using interval notation.)9 sin(x) ≤ 92
The values of x in the interval [0,2π] are given by:
[tex]\frac{5\pi}{6} \leq x\leq \frac{\pi}{6}[/tex]
What is the principal and general value of trigonometric ratios?The answers are known as principal solutions if the problem contains the variable 0 ≤ x < 2π. A general solution to a trigonometric equation is one that involves the integer "n" and provides all possible solutions.Given: 9 sin (x) [tex]\leq \frac{9}{2}[/tex]
To find: Values of x in the interval [tex][0,2\pi][/tex].
Finding:
As 9 sin (x) [tex]\leq \frac{9}{2}[/tex],
=> [tex]sin(x)\leq \frac{1}{2}[/tex]
As, [tex]sin (\frac{\pi}{6})=sin(\frac{1}{2})[/tex],
=> [tex]sin(x)\leq sin(\frac{\pi}{6})[/tex]
=> [tex]x\leq \frac{\pi}{6}[/tex], i.e., the principle value of x.
As sin (x) = sin (π - x), [tex]\pi -x\leq \frac{\pi}{6}[/tex]
=> [tex]\pi -\frac{\pi}{6}\leq x[/tex]
=> [tex]\frac{5\pi}{6}\leq x[/tex]
Hence, the values of x in the interval [0,2π] are given by:
[tex]\frac{5\pi}{6} \leq x\leq \frac{\pi}{6}[/tex]

Steve Conway wants his team to win more than 57 games this year. His team has already won 2 games this season and there are 5 more months to play. Based on his goal, how many games must his team win per month? Write answer as an inequality.
Answer:
11
Explanation:
Because 57 minus 2 games already equals 55, so 55 games divided by 5 months equals 11, so 11 games each month will get u to 57.
The number of games must his team win per month will be;
⇒ x > 11
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Steve Conway wants his team to win more than 57 games this year.
And, His team has already won 2 games this season and there are 5 more months to play.
Now,
Let number of games must his team win per month = x
So, We can formulate the inequality as;
⇒ 5x + 2 > 57
Solve for x as;
⇒ 5x > 57 - 2
⇒ 5x > 55
⇒ x > 11
Thus, The number of games must his team win per month will be;
⇒ x > 11
