Answer:

15x^4-5x^2+1

Step-by-step explanation:

g(x)=5x^2-1 and f(x)=3x^2-x+2

f(g(x))would mean that g(x) would be x in f(x).

So f(g(x) would be 15x^4-3-5x^2+1+2

simplified would be 15x^4-5x^2+1

What is the factored form of 64g^3+8

vivado [14]

$\bf \textit{difference and sum of cubes}
\\\\
a^3+b^3 = (a+b)(a^2-ab+b^2)\qquad
(a+b)(a^2-ab+b^2)= a^3+b^3 
\\\\
a^3-b^3 = (a-b)(a^2+ab+b^2)\qquad
(a-b)(a^2+ab+b^2)= a^3-b^3\\\\
-------------------------------\\\\
64g^3+8\implies 4^3g^3+8\implies (4g)^3+2^3
\\\\\\
(4g+2)[(4g)^2-(4g)(2)+2^2]\implies (4g+2)[(4^2g^2)-8g+4]
\\\\\\
(4g+2)(16g^2-8g+4)$

What is the perimeter of Triangle XYZ?

Svet_ta [14]

Answer:

Step-by-step explanation:

From the diagram, the following is true;

AY = YB = 7

BZ = ZC = 6

XC = XA = 5

perimeter of the triangle is the sum of all the sides

Hence ;

Perimeter = AY+YB+BZ+ZC+XC+XA

Perimeter of the triangle = 7+7+6+6+5+5

Perimeter of the triangle = 36

hence the perimeter of the triangle is 36
