Answer: x=-3

Step-by-step explanation:

First let's eliminate the square root

(\sqrt{x^2-5x+2})^2=(\sqrt{x^2+17})^2\\x^2-5x+2=x^2+17

Now subtract x^2\\ from both sides

x^2-5x+2-x^2=x^2+17-x^2\\-5x+2=17

Subtract 2 from both sides

-5x+2-2=17-2\\-5x=15

Finally divide both sides by -5

\frac{-5x}{-5} =\frac{15}{-5} \\x=-3

R is the midpoint of OP and QR is perpendicular to OP in the diagram below
dezoksy [38]

Answer:

24 in

Step-by-step explanation

Using pythagorean theorem, since OP is 20 inches and has a midpoint. RP= 10 and OR=10. The hypotenuse is given as 26 so do 26^2=10^2+a. 676= 100+a^2, subtract 100 from both sides. square root of 576 is 24

Un radar de l'armée américaine réussit à détecter tout ce qui se trouve à un rayon représenté
WARRIOR [948]

Répondre:

r <27

Explication étape par étape:

Compte tenu de l'inégalité 5r + 9> 10r - 126

Nous devons trouver l'ensemble de solutions

5r + 9> 10r - 126

Ajouter 126 des deux côtés

5r + 9 + 126> 10r - 126 + 126

5r + 135> 10r

5r-10r> -135

-5r> -135

Divisez les deux côtés par -5 (notez que le signe changera)

-5r / -6 <-135 / -5

r <27

Par conséquent, les ensembles de solutions sont des valeurs inférieures à 27
