(X+h)^3 + (x+h)-(x^3+x)

ICE Princess25 [194]

$\dfrac{(x+h)^3 + (x+h)-(x^3+x)}{h}=\\
\dfrac{x^3+3x^2h+3xh^2+h^3+x+h-x^3-x}{h}=\\
\dfrac{3x^2h+3xh^2+h^3+h}{h}=\\3x^2+3xh+h^2+1$

Triangle ABC has angle measures as shown.

sladkih [1.3K]

As with any triangle, the sum of angles is 180°.

(a)
(x -5) +(3x +30) +35 = 180 . . . . . sum of angles is 180
4x +60 = 180 . . . . . . . . . . . . . . . . collect terms
4x = 120 . . . . . . . . . . . . . . . . . . . . subtract 60
x = 30 . . . . . . . . . . . . . . . . . . . . . . divide by 4

(b)
Angle A = x -5 = 30 -5 = 25

Angle B = 3x +30 = 3*30 +30 = 120

Evaluate the expression when a= 4, b= - 2, and c= 7 - -> 5a - 9 (b - c)

ollegr [7]

Answer:

$65$

Step-by-step explanation:

Given the following question:

$5a-9(b-c)$
a = 4
b = 2
c = 7

In order to find the answer, we need to substitute the variables with the numbers given, and then solve using PEMDAS.

$5\times4-9\times(2-7)$
$2-7=-5$
$5\times4-9\times-5$
$5\times4=20$
$20-9\times-5$
$9\times-5=-45$
$20--45$
$20+45=65$
$=65$

Hope this helps.
