Answer:
a. (5x+2)(5x+2)
Step-by-step explanation:
You will recognize that the first (25x^2) and last (4) terms are perfect squares. The middle term is double the product of the roots of those squares:
2(5x)(2) = 20x
This means the given expression is a perfect square trinomial, and that it is the square of (5x+2). This matches the first choice.
25x^2 +20x +4 = (5x +2)^2 = (5x +2)(5x +2)
_____
Generically, ...
(a +b)^2 = a^2 +2ab +b^2
Here, we have a=5x, b=2.

A triangle has side lengths of 23 in, 6 in, and 28 in. classify it as acute right or obtuse
Answer:
In this case, the side lenghths don't even form a triangle. Since that is not an option, the triangle would be acute.
Step-by-step explanation:
if c^(2 )> a^(2)+b^(2) then the triangle is obtuse.
if c^(2 )< a^(2)+b^(2) then the triangle is acute.
if c^(2 )= a^(2)+b^(2) then the triangle is right
Hope this helps :)

Samantha's office recycled a total of 4.3 kilograms of paper over 4 weeks. How many weeks will it take Samantha's office to recycle a total of 19.35 kilograms of paper?
Answer:
18 weeks
Step-by-step explanation:
Calculation for How many weeks will it take Samantha's office to recycle
Based on the information given we would be using one relationship to solve for another
(4.3 kilograms / 4 weeks) = (19.35 kilograms / x weeks)
Now let calculate How many weeks will it take Samantha's office to recycle by solving for x
x=[(19.35 kilograms) (4 Weeks)] /4.3 kilograms
x=77.4/4.3 kilograms
x = 18 weeks
Therefore How many weeks will it take Samantha's office to recycle a total of 19.35 kilograms of paper will be 18 weeks.
plz help and show me the steps so I know how to do this!! thank you!!

What is the measure of A?
What is the measure of B?
<A = 72°
<B = 108°
Explanation :<A = <C
(5y - 3)° = (3y + 27)°
5y-3y = 27 + 3
2y = 30
y = 15
<A = (5y - 3)°
<A = (5 x 15) - 3
<A = 75 - 3
<A = 72°
<B + <A = 180°
<B + 72° = 180°
<B = 180° - 72°
<B = 108°
Cristina realizo sus pagos con su tarjeta de crédito, si el primero fue de 5.500.000 y el segundo por 3. 750 000
Answer:
Ver explicación
Step-by-step explanation:
La pregunta carece de detalles. Sin embargo, una posible pregunta podría ser calcular el total de pagos realizados con su tarjeta de crédito.
Para hacer esto, simplemente sumamos los dos pagos.
[tex]Pago\ 1 = 5,500,000[/tex]
[tex]Pago\ 2 = 3,750,000[/tex]
Entonces tenemos:
[tex]Total = Pago\ 1 + Pago\ 2[/tex]
[tex]Total = 5,500.000 + 3,750,000[/tex]
[tex]Total = 9,250,000[/tex]

(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
Lydia is at a coffee shop and knows she can spend no more than $65 before tax. She sees this price list in the coffee shop. Write a number in each blank to complete an inequality Lydia can use to find how many pounds of Pumpkin Spice coffee, p, she can buy along with 2 pounds of Dark Roast coffee.
Price chart :
Item Price per pound
Dark Roast Coffee $7.50
Pumpkin Spice Coffee $10.50
Breakfast Tea $23.50
Answer:
Step-by-step explanation:
4
Maximum amount to spend ≤ 65
Cost of dark roast coffee = $7.50
2 dark roast coffee= $7.50 * 2 = $15
Pumpkin Spice + dark roast ≤ amount to spend
Let pumpkin spice = x
Cost of pumpkin spice = $10.50
Dark Roast Coffee = y
10.50x + 2* 7.50 ≤ 65
10.50x + 15 ≤ 65
10.50x ≤ 65 - 15
10.50x ≤50
x ≤50 / 10.50
x ≤ 4.76
Number of pumpkin spice coffee that can be purchased is 4.

Find the value of X round to the nearest 10th law of cosines.
Image of triangle is missing, so i have attached it.
Answer:
x = 18
Step-by-step explanation:
From the diagram attached, we can see that the 3 given sides have dimensions of x, 16 and 30.
Also, we see the angle opposite the dimension of x is 30°
Thus,we can use law of cosine to fjnd the value of x. Thus:
x² = 16² + 30² - 2(16 × 30)cos 30
x² = 256 + 900 - (960 × 0.866)
x² = 324.64
x = √324.64
x = 18.02
Approximating to the nearest tenth gives; x = 18

Triangle B is acute because its smaller than a right triangle.
Need help on this please help
Answer:
204
Step-by-step explanation:
The area of the top triangle = 5*12/2 = 30
The area of the bottom triangle = 30
The hypotenuse of the top triangle is
5^2 + 12^2 = hypotenuse^2
25 + 144 = hypotenuse^2
169 = hypotenuse squared.
hypotenuse = sqrt(169)
hypotenuse = 13
Now the back face = 13 * 8 = 104
The area of the left side rectangular face = 5*8 = 40
The total area = 30 + 30 + 104 + 40 = 204
