PLZ HELP Find the value of x that makes ΔXYZ~PQR

Mathematics
1 answer:
Galina-37 [17]3 years ago
6 0

Answer:

x = 8

Step-by-step explanation:

\triangle XYZ \sim\triangle PQR... (GIVEN) \\\therefore \frac{XY}{PQ} = \frac{YZ}{QR}.. (csst) \\\therefore \frac{20}{30}= \frac{x+6}{21}\\\therefore \frac{2}{3}= \frac{x+6}{21}\\\therefore \frac{2\times 21}{3}= {x+6}\\\therefore 14= {x+6}\\\therefore 14-6= {x}\\\therefore 8= {x}\\\huge \orange{\boxed {\therefore x = 8}}

Use the rational zero theorem to create a list of all possible rational zeros of the function f(x)=14x7-4x2+2
frosja888 [35]

Answer:

Factor this polynomial:  

F(x)=x^3-x^2-4x+4

Try to find the rational roots. If p/q is a root (p and q having no factors in common), then p must divide 4 and q must divide 1 (the coefficient of x^3).  

The rational roots can thuis be +/1, +/2 and +/4. If you insert these values you find that the roots are at  

x = 1, x = 2 and x = -2. This means that  

x^3-x^2-4x+4 = A(x - 1)(x - 2)(x + 2)  

A = 1, as you can see from equation the coefficient of x^3 on both sides.  

Typo:  

The rational roots can be  

+/-1, +/-2 and +/-4
