B. 6x3 + 16x2 − 6x − 16
C. 6x2 + 10x − 16
D. 5x2 + 10x − 16
Answer:
6x3+10x2−16x or A
Step-by-step explanation:
I used an algebra calculator because im too lazy to work it out.
^algebra^
(3x2 + 8x)(2x − 2)
=3x²(2x-2)
=6x³ - 6x²
+8x(2x - 2)
=16x² - 16x
put it all together
=6x³ - 6x² + 16x² - 16x
group according to variables, then count
6x³ + (-6x² + 16x²) - 16x
=6x³ + (+10x²) - 16x
=6x³ + 10x² - 16x

Find the total value of an investment of $12,700 at 8.8% for 1 year to the nearest dollar.
Answer:
$13,817.60
Step-by-step explanation:
Interest earned = $12,700 × [tex]\frac{8.8}{100}[/tex] × 1
= $1,117.60
Total earned = $1,117.60 + $12,700
= $13,817.60

What is base and power?Raising a base number to an exponent is referred to as "power" in mathematics. It indicates that "base number" and "exponent" are the two fundamental components of powers. The exponent shows how many times the base number has been multiplied, whereas the base number is defined as a number that is multiplied by itself.
In a nutshell, power is a number that has exponents used to express it. It means that the same element has been multiplied repeatedly. In the context of powers, the following specific terminology may be used:
Whenever a number:
Squared = power is 2
cubed = Power is 3
to the power of n = used for powers more than 3
The data given gives as an equation as followed
⇒ [tex]4^{2x}[/tex] ÷ [tex]8^x[/tex] = 32
⇒ [tex](2^2)^{2x}[/tex] ÷ [tex](2^3)^{x}[/tex] = 32
⇒ [tex]2^{4x}[/tex] ÷ [tex]2^{3x}[/tex] = 32
⇒ [tex]2^{(4x - 3x )}[/tex] = 32 (If the base is same in a division, then the powers
⇒ [tex]2^x[/tex] = 32 can simply be subtracted with the base as common)
⇒ 2 = [tex]\sqrt[x]{32}[/tex]
⇒ 2 = [tex]\sqrt[5]{32}[/tex]
Thus, x = 5

Step-by-step explanation:
4 ounce costs $1.79
12 ounce costs $4.11
$1.79 ÷ 4 = 0.4475 per ounce
$4.11 ÷ 12 = 0.3425 per ounce
0.3425 < 0.4475
So the 12 ounce tube is the better buy becaus it is cheaper per ounce.

Write a function that could be used to calculate the altitude of a plane arriving at JFK
International airport which was cruising at an altitude of 30,000 before it began its descent at a rate of 3,200 feet per minute. How many minutes would it be before the plane landed. Round your answer to the nearest tenth.
Answer:
The plane landed after 9.4 minutes.
Step-by-step explanation:
Function Modeling
The initial altitude of a plane arriving at JFK International Airport is 30,000 ft.
It then began its descent at a rate of 3,200 feet per minute.
Let's call t the number of minutes since the descent started. If each minute the plane descends 3,200 feet, then after t minutes it descends 3,200t.
This must be subtracted from the initial altitude, thus the altitude H is written as:
H = 30,000 - 3,200t
When the plane landed, its altitude was H=0, thus:
0 = 30,000 - 3,200t
Adding 3,200t:
3,200t = 30,000
Dividing by 3,200:
t = 30,000/3,200
t = 9.375 minutes
Rounding to the nearest tenth:
The plane landed after 9.4 minutes.

3x+ −1/3y+1/3y=20+1/3y(Add 1/3y to both sides)
3x=1/3y+20
[tex]3=\frac{1}{3}\frac{}{} y\frac{+20}{3}[/tex] Divide both sides by 3
x[tex]=\frac{1}{9} y +\frac{20}{3}[/tex]
Substitute 1/9y+20/3 for x in−18x+2y=−30
−18x+2y=−30
-18[tex](\frac{1}{9}y +\frac{20}{3} +2y=-30[/tex])
−120=−30 (Simplify both sides of the equation)

What is the volume of the figure? Enter the answer in the box.
cubic centimeters
Answer:
35cm
Step-by-step explanation:
The volume of the figure is sum of the two individual cuboids which is
164 cm³.
What is a cuboid?A cuboid is a three-dimensional closed figure which has volume along with surface area.
The volume of a cuboid is the product of its length, width, and height.
The total surface area of a cuboid is 2(lw + wh + wl) and the lateral surface area is 2(l + w)×h.
The total volume of the given figure would be the sum of the two cuboids
which is,
= (5×5×8) + (8×8×1) cm³.
= 200 + 64 cm³.
= 264 cm³.
