I suppose you just have to simplify this expression.
(2ˣ⁺² - 2ˣ⁺³) / (2ˣ⁺¹ - 2ˣ⁺²)
Divide through every term by the lowest power of 2, which would be x + 1 :
… = (2ˣ⁺²/2ˣ⁺¹ - 2ˣ⁺³/2ˣ⁺¹) / (2ˣ⁺¹/2ˣ⁺¹ - 2ˣ⁺²/2ˣ⁺¹)
Recall that nª / nᵇ = nª⁻ᵇ, so that we have
… = (2⁽ˣ⁺²⁾ ⁻ ⁽ˣ⁺¹⁾ - 2⁽ˣ⁺³⁾ ⁻ ⁽ˣ⁺¹⁾) / (2⁽ˣ⁺¹⁾ ⁻ ⁽ˣ⁺¹⁾ - 2⁽ˣ⁺²⁾ ⁻ ⁽ˣ⁺¹⁾)
… = (2¹ - 2²) / (2⁰ - 2¹)
… = (2 - 4) / (1 - 2)
… = (-2) / (-1)
… = 2
Another way to get the same result: rewrite every term as a multiple of y = 2ˣ :
… = (2²×2ˣ - 2³×2ˣ) / (2×2ˣ - 2²×2ˣ)
… = (4×2ˣ - 8×2ˣ) / (2×2ˣ - 4×2ˣ)
… = (4y - 8y) / (2y - 4y)
… = (-4y) / (-2y)
… = 2

Step-by-step explanation:
p(x)= 4x^3 -3x^2+5x-2
Answer:
p=4x^3−3x^2+5x−2/x
Step-by-step explanation:
Let's solve for p.
px=4x^3−3x^2+5x−2
Step 1: Divide both sides by x.
px/x=4x^3−3x^2+5x−2/x
p=4x^3−3x^2+5x−2/x
Answer:
p=4x^3−3x^2+5x−2/x

If sinA = cosB, what is the relationship between A and B if A is obuse angled and B is acute angled ?
Answer:
According to the law of sines, \dfrac{AB}{\sin(\angle C)}=\dfrac{AC}{\sin(\angle B)}
sin(∠C)

AC
start fraction, A, B, divided by, sine, left parenthesis, angle, C, right parenthesis, end fraction, equals, start fraction, A, C, divided by, sine, left parenthesis, angle, B, right parenthesis, end fraction. Now we can plug the values and solve:
\begin{aligned} \dfrac{AB}{\sin(\angle C)}&=\dfrac{AC}{\sin(\angle B)} \\\\ \dfrac{5}{\sin(33^\circ)}&=\dfrac{AC}{\sin(67^\circ)}\\\\ \dfrac{5\sin(67^\circ)}{\sin(33^\circ)}&=AC \\\\ 8.45&\approx AC \end{aligned}

Answer:
-7/4
Step-by-step explanation:
Slope is (y₂ - y₁) / (x₂ - x₁)
Using this, plug in the values they give.
(6 - (-1)) / (-4 - 0)
Simplify.
7 / (-4)
-7 / 4
The slope is - 7/4, or -1 3/4 ( negative 1 and three fourths)

Fred's restaurant is famous for its fresh fruit smoothies . Fred's recipe calls for 1/3 of an apple, 1/4 of a lemon, and 2/3 of a peach to make a single smoothie . A family of 6 arrives at fred's restaurant. How much of each fruit does fred need to make smoothies for entire family?
Answer: 2 apples, 1 1/2 lemon and 4 peach
Step-by-step explanation:
Fruits used for Fred's recipe fur a single smoothie:
Apple = 1/3
Lemon = 1/4
Peach = 2/3
When the family of 6 arrived, the fruits needed to make smoothies for entire family will be:
Apple = 1/3 × 6 = 2
Lemon = 1/4 × 6 = 1 1/2
Peach = 2/3 × 6 = 4

Enter the x-coordinate of the solution to this system of equations
−2x−y=6
8x+3y=−28
x= ?
I have trouble with these kinds of problems so a mini explanation would really help me out :)
Answer:
equation 2into minus 3 into equation 1
8x+ 3y= -28
-3x-3y=18
----------------
5x=10
x =2
put value of y in equation 2
8 into 2+3y=-28
16+3y= -28
3y= -28+16
3y= -12
y= -4

find a6 for an arithmetic sequence where a1=3x+1 and d=2x+6
Answer:
a₆ = 13x + 31
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
Here a₁ = 3x + 1 and d = 2x + 6 , then
a₆ = 3x + 1 + 5(2x + 6)
= 3x + 1 + 10x + 30
= 13x + 31

3 x (7 + 5) /4 +2
Using PEMDAS so...
3 x (12)/4 +2
36/4 +2
9 +2
=11
Answer:
7
Step-by-step explanation:
PEMDAS:
P = ( )
(7 + 5) = 12
E = exponent
M = x
3 x 12 = 36
D = / or ÷
36 / 4 = 9
A = +
S = -
9 - 2 = 7

Answer:
angles: ∠J≅∠P, ∠K≅∠M, ∠L≅∠N
sides: JK ~ PM, KL ~ MN, LJ ~ NP
Step-by-step explanation:
The similarity statement lists corresponding parts in the same order. For example, the first letter of one triangle designator corresponds to the first letter of the other triangle designator.
It is easy to list corresponding angles. Simply list them in the same order as they show up in the similarity statement.
angles: ∠J≅∠P, ∠K≅∠M, ∠L≅∠N
__
Likewise, corresponding segments are those between corresponding vertices. If a segment uses letter designations 2 and 3 in one triangle (KL), it will use letter designations 2 and 3 in the other triangle (MN).
sides: JK ~ PM, KL ~ MN, LJ ~ NP
_____
Additional comment
I sometimes find it easier to list the vertices vertically. Then I can see the correspondence more directly.
J . . P
K . . M
L . . N
