This is the answer for this question.
Answer:
9
Step-by-step explanation:
Points R, S, and T are collinear.
RT = x + 5
ST = 4x - 9
RS = x - 2
First, create an equation to find the value of the variable x
RS + ST = RT (segment addition postulate)
(x - 2) + (4x - 9) = (x + 5) (substitution)
Solve for x
x - 2 + 4x - 9 = x + 5
Collect like terms
5x - 11 = x + 5
5x - x = 11 + 5
4x = 16
Divide both sides by 4
4x/4 = 16/4
x = 4
RT = x + 5
Plug in the value of x
RT = 4 + 5
RT = 9
<span>If F(x) =3x^2 and G(x) =x+2, find (F*G)(x)
</span> (F*G)(x) = 3x^2 (x+2)
(F*G)(x) = 3x^2 (x) + 3x^2(2)
(F*G)(x) = 3x^3 + 6x^2

Answer:
$16.43
Step-by-step explanation:
15.50 x .06 [wonder how i got .06? 6%= .06]
= .93
here's where most people mess up, the usually forget to add the tax to the original cost.
15.50 + .93
= $16.43
Answer:
AE = 15 cm; ED = 18 cm; AD = 15 cm (given)
Step-by-step explanation:
ΔBEC ~ ΔAED so ...
AD/BC = AE/BE = (BE+AB)/BE = 1 + AB/BE
Substituting given numbers (lengths in centimeters), we have ...
15/10 = 1 + 5/BE
1/2 = 5/BE
BE = 10
Similarly, ...
1/2 = 6/CE
CE = 12
Then the unknown sides are ...
AE = AB + BE = 5 + 10 = 15 . . . cm
ED = CE + CD = 12 + 6 = 18 . . . cm
