sorry about your other question but here is the answer to this one


ok so her is what I think you do...

you have the equation y=3(x+1)^2+4 you use the distributive property to get rid of the prenticies so 3*x=3x and 3*1=3.  

Then you have y=3x^2+3^2+4 both of the numbers have a square root because the 2 beside the parinticies so both of those are squared

then u square what you can square so it would them be y=3x^2+9+4 because you can't square a variable and a number  it stays the same but because 3^2 can be squared is become 3*3 which equals 9

Then u combine the like terms you have making it y=3x^2+13 because of 9+4=14

then it says that y=x^2        so you put x^2=3x^2+13

after that you subtract -3x^2 from both sides making it -2x^2=13 because +x^2-3^2=-2x^2 and 3x^2-3x^2=0 so that goes away and you keep the +13

that is when you would divide by -2 on both sides making it -x^2=-13/2 which also equals -6.5(we will be using the decimal soon) because -2^2 divided by -2=-x^2 and 13 divided by -2 is -6.5

then u would find the square root of that by-{equation:\/(-x^2)=\/(-6.5)} -->\/(-x^2) which equals x because we don't know what x is it turns into jus x then as we move on =\/(-6.5)  which when you use a calculator it equals 2.54950976 but I would just round to the nearest hundreths making it 2.55 and that would be your answer

The width of rectangle A is the sum of twice a number and 8. The length of the rectangle is 3 times as great as the width. If th
Galina-37 [17]
Formula for perimeter of a rectangle = 2(L + W)
let the number be x
width = 2x + 8
length = 3(2x + 8)
substitute respectively
96 = 2 (2x + 8 + 3(2x + 8)) open the bracket
96 = 2 ( 2x + 8 + 6x + 24) collect like terms
96 = 2 (8x + 32) open the bracket
96 = 16x + 64
collect like terms
96 - 64 = 16x
32 = 16x
divide both sides by 16
32/16 = 16x/16
2 = x
therefore, the width = 2x + 8 = 2(2) + 8 = 4 + 8 = 12.
and the length = 3(2x + 8) = 6x + 24 = 6(2) + 24 = 12 + 24 = 36.

HELPPPP PLEASSEEEEE Literal Equations and Formulas
Lapatulllka [165]

Answer:

Im pretty sure A

Step-by-step explanation:

multiply both sides by 3/4 (reciprocal)

3/4X=pie(r)cubed

divide by pi on both sides

3/4X

-------- = r(cubed)

pi

cube root both sides

In triangle MNO shown below, segment NP is an altitude:
Effectus [21]

Answer:  C. Definition of an Altitude

Step-by-step explanation:

Given: In triangle MNO shown below, segment NP is an altitude from the right angle.

Let ∠MNP=x

Then ∠PNO=90°-x

Therefore in triangle MNO,

∠MPN=∠NPO =90°  [by definition of Altitude]

[Definition of altitude : A line which passes through a vertex of a triangle, and joins the opposite side forming right angles. ]

Now using angle sum property in ΔMNP

∠MNP+∠MPN+∠PMN=180°

⇒x+90°+∠PMN=180°

⇒∠PMN=180°-90°-x

⇒∠PMN=90°-x

Now, in ΔMNO and ΔPNO

∠PMN=∠PNO=90°-x

and ∠MPN=∠NPO =90°  [by definition of altitude]

Therefore by AA similarity postulate, we have

ΔMNO ≈ ΔPNO

5/8-11/20=?<br><br> Help what’s the answer I’m stuck on finding the LCM of the denominators
zhannawk [14.2K]

Answer:

3/40

Step-by-step explanation:

  • \frac{5}{8} - \frac{11}{20}
  • \frac{25}{40} - \frac{22}{40} (LCM is 40)
  • \frac{25-22}{40}
  • \frac{3}{40}

Therefore, the answer is 3/40!

Write a complete sentence that states the type of transformation that was performed and explains the transformation in detail. Q
Cerrena [4.2K]
The type of transformation that has happened is a translation. Translation is when the image's size nor shape changes after transformation. every point in the image moves the same distance in the same direction.
the equation for the translation mentioned is;
T4, -5(x,y)
this means that every point in the image has moved down by 5 units and moved to the right by 4 units.
Point A to Point E
Point A - (-4,-1)
after translation (x+4, y-5) = (-4+4,-1-5)
                                          = (0,-6) these are the coordinates of point E.
the other three points too have moved the same distance and direction as point  A did.
