What is a perfect square polynomial?If a polynomial p(x) can be written as:
[tex]p(x) = [f(x)]^2[/tex]
where f(x) is also a polynomial, then p(x) is called as perfect square polynomial
For the considered case, the polynomial specified is;
[tex]g(x) = 40x + 4x^2[/tex]
Case 1: Converting to vertex form[tex]g(x) = 40x + 4x^2\\g(x) = 4(x^2 + 10) = 4(x^2 + 10 + 25 -25)\\g(x) = 4(x^2 + 10 + 25) - 100 = 4(x+5)^2 - 100\\[/tex]
Thus, the vertex form of the considered polynomial is [tex]g(x) = 4(x+5)^2 - 100[/tex]
Case 2: Converting to standard formStandard form of a quadratic polynomial is [tex]ax^2 + bx + c[/tex]
Thus, we get: the considered polynomial in standard form as:

Case 3: Factoring the first two terms of polynomial[tex]g(x) = 40x + 4x^2 \\g(x) = 4x(10 + x)[/tex]
Case 4: Forming a perfect square trinomialThe considered polynomial has only two terms, therefore, its not a trinomial.

The original price of a T-Shirt is $15. The T-Shirt is on sale for 35% off. What is the sale price?
Answers
Answer:
9.75$
Step-by-step explanation:
Answer:
9.75$
Step-by-step explanation:
The original price of the shirt is $15, and it's on sale for 35% off. What is the item's sale price?
First, convert the 35% to a real mathematical number. For percents, this is always done by dividing the 35% by 100%, or 35% / 100% = 0.350.
Second, find out what 35% of $15 is. This is the amount of the sale discount. This is always found by multiplying 0.350 by the item's cost $15, like this:
0.350 x $15 = $ 5.25.
So for this sale, you'll save $ 5.25 on this item.
This means, the cost of the item to you is
$15 - $ 5.25 = $ 9.75.

Answers
Answer: 5 + 3x ≤ 20; 5
Step-by-step explanation:
at most means not more than(less or equal to),which use the symbol ≤. Let x be the hour that Max rent.

Step-by-step explanation:
first equation: 6x+4y=1250
second equation: x+y=220
work:
6x+4y=1250 (-1)
x+y=220 (6) we eliminate x, that's why I multiply each term by 6 and -1
-6x-4y=-1250
6x+6y=1320
2y=70
2y/2=70/2
y=35 (I used y for adults)
x+35=220
x=220-35

Write a equation: Two thirds of a number decreased by the product of a number and two, squared, is 43 (PLEASE ANSWER ASAP )
Answers
We can transform the mathematical sentence into the equation:
(2/3)*x - (2*y)^2 = 43
How to write the equation?
Here we have the sentence:
" Two thirds of a number decreased by the product of a number and two, squared, is 43"
First, we can define x as "the number"
Then:
" Two thirds of a number..." is:
(2/3)*x
Now we add the next part:
"... decreased by the product of a number and two, squared, is 43"
Assuming that this is another number, let's call it y, we have:
(2/3)*x - (2*y)^2 = 43
This is our two-variable equation.

of March?
O $3,750
$312.50
O $87.50
O $225.00
Answers
Answer:
87.50
Step-by-step explanation:
75,000 x 28% ÷ 12
She will budget $225 for her emergency savings for the month of March
How to determine the amount saved for emergency?We have:
Gross = $75,000 per year.
Payroll deductions = 28%
So, the net pay is:
Net = (1 - 28%) * $75,000
Evaluate
Net = $54000
The net income per month is:
Monthly = $54000/12
Evaluate
Monthly = $4500
5% of her net income goes to emergency.
So, we have:
Emergency = 5% * $4500
Evaluate
Emergency = $225
Hence, she will budget $225 for her emergency savings for the month of March

Two joggers set out at the same time from their homes 21 miles apart. They agree to meet at a point somewhere in

Answers
The two joggers who are 21 miles apart travel at a speed 8 mph and 6 mph respectively and would meet after one and half hours.
What is an equation?An equation is an expression used to show the relationship between two or more variables and numbers.
Let a represent the speed of the faster jogger and represent the speed of the other jogger. Hence:
a = b + 2 (1)
Also:
In one and half hour (1.5 h):
a = d₁/1.5
d₁ = 1.5a
b = d₂/1.5
d₂ = 1.5b
d₁+ d₂ = 21
1.5a + 1.5b = 21 (2)
From both equation 1 and 2:
a = 8, b = 6
The speed of the joggers is 8 mph and 6 mph respectively.
