The answer is 7:9. Divide each side by two. So 14/2= 7, 18÷2=9. Hope this helps!

9:7
Ratios are always simplified so by dividing both 18 and 14 by 2 you get 9 and seven. Because yellow triangles is stated first the 9 is put before the 7 blue triangles.

Identify all of the root(s) of g(x) = (x2 + 3x - 4)(x2 - 4x + 29).
Gennadij [26K]

we have

g(x)=(x^{2}+3x-4)( x^{2}-4x+29)

To find the roots of g(x)

Find the roots of the first term and then find the roots of the second term

Step 1

Find the roots of the first term

(x^{2}+3x-4)=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(x^{2}+3x)=4

Complete the square. Remember to balance the equation by adding the same constants to each side

(x^{2}+3x+1.5^{2})=4+1.5^{2}

(x^{2}+3x+1.5^{2})=6.25

Rewrite as perfect squares

(x+1.5)^{2}=6.25

Square root both sides

(x+1.5)=(+/-)2.5

x=-1.5(+/-)2.5

x=-1.5+2.5=1

x=-1.5-2.5=-4

so the factored form of the first term is

(x^{2}+3x-4)=(x-1)(x+4)

Step 2

Find the roots of the second term

(x^{2}-4x+29)=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(x^{2}-4x)=-29

Complete the square. Remember to balance the equation by adding the same constants to each side

(x^{2}-4x+4)=-29+4

(x^{2}-4x+4)=-25

Rewrite as perfect squares

(x-2)^{2}=-25

Remember that

i=\sqrt{-1}

Square root both sides

(x-2)=(+/-)5i

x=2(+/-)5i

x=2+5i

x=2-5i

so the factored form of the second term is

(x^{2}-4x+29)=(x-(2+5i))(x-(2-5i))

Step 3

Substitute the factored form of the first and second term in g(x)

g(x)=(x-1)(x+4)(x-(2+5i))(x-(2-5i))

therefore

the answer is

the roots are

x1=1\\x2=-4\\x3=(2+5i)\\x4=(2-5i)
