Find the values of x and y if
soldi70 [24.7K]

Answer:

see explanation

Step-by-step explanation:

Since the triangles are congruent then corresponding sides are congruent, then

CA = NE , that is

4x + 3 = 11 ( subtract 3 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2

----------------------------------------

AR = EW, that is

4y - 12 = 10 ( add 12 to both sides )

4y = 22 ( divide both sides by 4 )

y = 5.5

-------------------------------------------

NW = x + y = 2 + 5.5 = 7.5

CR = NW = 7.5

What is (f⋅g)(x)? f(x)=x^2−3x+2 g(x)=x^3−8 Enter your answer, in standard form, in the box. (f⋅g)(x)=
uysha [10]

Answer:

f(g(x))=x^{6}-19x^{3}+90

Step-by-step explanation:

We have been given the following equations;

f(x)=x^2−3x+2

g(x)=x^3−8

We are required to determine the composite function (f⋅g)(x). This simply means that we shall substitute the function g(x) in place of x in the function f(x);

f(g(x)) = g(x)^{2}-3g(x)+2\\\\f(g(x))=(x^{3}-8)^{2}-3(x^{3}-8)+2\\\\f(g(x))=x^{6}-16x^{3}+64-3x^{3}+24+2\\\\f(g(x))=x^{6}-19x^{3}+90

Completely factor the polynomial. 4x^2 20x 25
Sergeu [11.5K]
I use the railroad method so here's how I would solve it:
4 x 25 = 100
10 x 10 = 100, 10 + 10 = 20
(x +10/4)(x + 10/4)
(x + 5/2)(x + 5/2)
The answer should be: (2x + 5)(2x + 5)

It can be checked:
2x x 2x = 4x^2
2x x 5 = 10x 
5 x 2x = 10x
5 x 5 = 25 
4x^2 + 20x + 25

So yes, the answer would be (2x + 5)(2x + 5)
