Look at the picture.

$ZY = 5+3=8$

For XY and ZX use the Pythagorean theorem.

$XY^2=3^2+4^2\\\\XY^2=9+16\\\\XY^2=25\to XY=\sqrt{25}\\\\XY=5$

$ZX^2=5^2+4^2\\\\ZX^2=25+16\\\\ZX^2=41\to ZX=\sqrt{41}$

The perimetero fo XYZ:

$P_{\triangle XYZ}=8+5+\sqrt{41}=\boxed{13+\sqrt{41}}$

Solve √(3x+7)+2√(x-8)=0.

laiz [17]

Answer:

The solution to this question is 39

Step-by-step explanation:

Given that :

√(3x+7)+2√(x-8)=0.

√(3x+7)=-2√(x-8) (i)

square of the equation (i)

Then

(√(3x+7))^2=(-2√(x-8))^2

we know that √a*√a=(√a)^2=a So,

(3x+7)=4(x-8)

3x+7=4x-32 //multiply by 4

32+7=4x-3x exchange the value.

39=1x

x=39.
