1) Rewrite it in the form a^2-2ab+b^2, where a=11m and b=9

(11m)^2-2(11m)(9)+9^2

2) Use Square of Difference: (a-b)^2=a^2-2ab+b^2

(11m-9)^2

Your answer is (11m-9)^2

Is triangle VUW similar to triangle VXY? If yes, explain how you know. If no, explain why not.

antoniya [11.8K]

Answer:

Yes, because m<UVW is congruent with m<XVY and m<VUW is congruent with m<VXY

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are equal

In this problem

m<VXY=m<VUW ------> by corresponding angles

m<XVY=m<UVW -----> is the same angle

therefore

m<XYV=m<UWV -------> because the sum of the interior angles in a triangle must be equal to 180 degrees

therefore

Triangles VUW and VXY are similar by AA Similarity Postulate------> The three internal angles are congruent

F(x) = 2x^3 g(x) = x-3 find f(2) find g(4) find (f+g) (x)

rjkz [21]

$f(x) = 2 {x}^{3}$

$f(2) = 2 \times {2}^{3} = 2 \times 8 = 16$

_________________________________

$g(x) = x - 3$

$g(4) = 4 - 3 = 1$

_________________________________

$(f + g)(x) = f(x) + g(x)$

$(f + g)(x) = 2 {x}^{3} + x - 3$

Answer:

N = 10

Step-by-step explanation:

-17+ x/5 = 33

You have to find x, in this case is N

x/5 = 33 + 17

x/5 = 50

x= 50/5

x =10

N= 10

C=-7/15 and x=2/5 c-4x write your answer in simplest form

pogonyaev

9514 1404 393

Answer:

-31/15

Step-by-step explanation:

Put the numbers in the expression and do the arithmetic.

$c-4x=-\dfrac{7}{15}-4\cdot\dfrac{2}{5}=-\left(\dfrac{7}{15}+\dfrac{8}{5}\right)\\\\=-\left(\dfrac{7}{15}+\dfrac{24}{15}\right)=\boxed{-\dfrac{31}{15}}$

Your graphing calculator can probably help with this.
