Which of the following is perfect square trinomial. Ive asked 4 times. Please Help. Will give brainlilest
Answer:
D
Step-by-step explanation:
a perfect square trinomial is
[tex]a^2x^2\pm2(ab)xy+b^2y^2[/tex]
factorized is
[tex](ax\pm by)^2[/tex]
so as you can see option A and B can't be, because they have -49y^2 and it has to be plus
so the other options are C and D
in the trinomial a=4 and b=\pm 7
the roots of a^2 and b^2
[tex]\pm2abxy=\pm2(4)(7)xy\\\\=\pm56xy[/tex]
so it's option d with b=-7
[tex]16x^2-56xy+49y^2[/tex]

Answer:
20%
Step-by-step explanation:
You would have to add 1200 and 300 to get the total amount of students which would be 1500.
Then put 1500 as the denominator and 300 as the numerator since we're talking about the number of students that did NOT wear their school colors. our fraction should then be 300/1500.
If you cross out 2 zeros on both numbers, you'll get 3/15. if you reduce that you get 1/5. 1/5= 20%

Please help shouldn't be 38?
Answer:
No it is D.52
Step-by-step explanation:
The angle has to equal 180 degrees.
180-76=104
52 time 2 equals 104
104=104
Answer:
[tex]\boxed {\tt D. \ x=52}[/tex]
Step-by-step explanation:
The 2 angles are 2x and 76. They are on a straight line together. Therefore they are supplementary and add to 180 degrees.
[tex]2x+76=180[/tex]
Solve for x by isolating x on one side of the equation.
76 is added to 2x. The inverse of addition is subtraction. Subtract 76 from both sides of the equation.
[tex]2x+76-76=180-76\\2x=180-76\\2x=104[/tex]
x is multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.
[tex]2x/2=104/2\\x=104/2\\x=52[/tex]
x is equal to 52 and D is the correct answer.

Graph the line passing through (2,-5)whose slope is m=1/2
9514 1404 393
Answer:
see attached
Step-by-step explanation:
If you're graphing by hand, plot the point (2, -5), then draw a line through it with a slope of +1/2. Such a line will have a rise of 1 unit for each run of 2 units to the right. That is, (2, -5) +(1, 2) = (3, -4) will be another point on the line. You can draw the line through these two points.
__
When you are given a point and a slope, it is convenient to know the point-slope form of the equation of a line:
y -k = m(x -h) . . . . . line with slope m through point (h, k)
Here, the equation can be ...
y -(-5) = (1/2)(x -2)
y +5 = (1/2)(x -2)
A graphing calculator can draw the graph of this very nicely.

Answer: 36 times
Step-by-step explanation: 54 divided by 12 is 4.5 so he makes 4.5 every time so if he went for 8$ he would get 36 because 4.5 times 8 equals 36 so he will drive around the track 36 times and make 8$
A recipe for orange water says, “Mix 3 teaspoons of yellow water with 1 teaspoon red water.” For this recipe, we might say: “The ratio of teaspoons of yellow water to teaspoons of red water is 3:1.” 1. Write a ratio for 2 batches of this recipe. 2. Write a ratio for 4 batches of this recipe
Well, we know that 3:1 is one batch of orange water. We also know that there are 2 things to focus on.
1. Must write ratio for 2 batches of the recipe.
2. Must write ratio for 4 batches of the recipe.
To make this equation simple, double the ratio to find 2 batches because all it means is 2x more water.
3:1
x2
6:2
So, the ratio would be 6:2 to make 2 batches.
To make it easier again, we just multiply the ratio of 2 batches by 2 which would find the ratio for 4 batches.
6:2
x2
12:4
So that means, that it is 6:2 for 2 batches, and 12:4 for four batches.

I think its 17+3r=v so D?? I'm not entirely sure but I believe that's it lol
Michael lives 2 3/5 miles away from the school Sarah lives 1/2 as long as Michael how far does Sarah live from the school
Answer:
Let's see what to do buddy...
Step-by-step explanation:
[tex]2 \frac{3}{5} miles = \frac{10}{5} + \frac{3}{5} \: miles = \frac{13}{5} \: miles \\ [/tex]
So Michael lives 13/5 miles away from the school.
_________________________________
Sarah lives 1/2 as long as Michael.
So the distance from the school of where Sarah's house located is 1/2 distance from the school of where Michael's house located.
Which means :
[tex] \frac{13}{5} \div 2 = \frac{13}{5} \times \frac{1}{2} = \frac{13}{10} \\ [/tex]
And we're done.
Thanks for watching buddy good luck.

Suppose you go fishing at a local stream that is known for its rainbow trout. The stream has rules about rainbow trout. If they are unusually small, they have to be released back in the stream. All others can be kept or released. If they are unusually large, you're definitely going to want to take a picture for the local fish shop. Rainbow trout in this steram have a mean length of 18.3 inches and a standard deviation of 3.2 inches. Their lengths follow a normal distribution.
