Rewrite 14a5b + 7ab2 using a common factor.
7ab(2a5b + 7ab2)
7ab(2a4 + b)
14ab(2a4 + 7ab2)
21a5b(7 + 3ab2)
Answer:
[tex]7ab(2 {a}^{4} + b)[/tex]
Step-by-step explanation:
We want to pull out common factors.
[tex]14{a}^{5}b[/tex]
[tex]7a{b}^{2}[/tex]
Common factors between 14 & 7? 7
Common factors between a5b & ab2? ab
[tex]7ab(2 {a}^{4} + b)[/tex]
Check
[tex]7ab(2 {a}^{4} + b) \\ 7ab(2 {a}^{4} ) = 14 {a}^{5}b \\ 7ab( b) \: = 7a {b}^{2} \\ = 14{a}^{5}b + 7a {b}^{2}[/tex]

so 4(6k+4) = (4x6)k + (4x4)
which gets you to
5k + 24k + 16 - 29k = 16
simplified down to
29k + 16 -29k = 16

$105.00
thx!
Answer:
122.50
Step-by-step explanation:
multiply 35 x 1.5 which gives you 52.5 add 70 which gives you the answer of 122.50. Hope it helps!
Answer:
B. $122.50
Step-by-step explanation:
its $122.50 because 35 divided in half is 17.50 and the plume worked 1.5 hours so 35 + 17.50 + 70 = $122.50
The data shows how many videos were rented for a forty-day period. Which table matches the information data that was collected?
Which equation is equivalent to this proportion? Select all that apply.
Answer:
250y = 800
Step-by-step explanation:
[tex]\frac{8}{250}[/tex] = [tex]\frac{y}{100}[/tex] Cross multiply
250y = 800
Answer:
A) 250y = 800
Step-by-step explanation:
Given equation:
[tex]\dfrac{8}{250}=\dfrac{y}{100}[/tex]
Cross multiply by multiplying the numerator and denominator of the first fraction by the denominator of the second fraction, and multiplying the numerator and denominator of the second fraction by the denominator of the first fraction:
[tex]\implies \dfrac{8 \times 100}{250\times 100}=\dfrac{y \times 250}{100 \times 250}[/tex]
Simplify:
[tex]\implies 8 \times 100 = y \times 250[/tex]
[tex]\implies 800=250y[/tex]
[tex]\implies 250y=800[/tex]

AND 100 POINTS!(if you awncer all)
The correct answer is a) Lunar eclipses can be viewed from more places on Earth than solar eclipses. This is because lunar eclipses are visible from any location on the night side of Earth, whereas solar eclipses are only visible from certain locations along the Moon's shadow path.
The correct answer is c) the changes of the seasons on Earth. The amount of sunlight that strikes different parts of Earth due to Earth's tilt on its axis affects the seasons on Earth because it determines the length of the days and the angle at which sunlight hits the Earth, which in turn affect the temperature and weather patterns in different regions.
The correct answer is b) Kinesha is incorrect because a solar eclipse occurs when the Moon is directly between the Sun and Earth. A solar eclipse occurs when the Moon is directly between the Sun and Earth, and the Moon's shadow is cast on Earth. In this configuration, Earth is not located between the Sun and the Moon.
The correct answer is b) new moon. During the new moon phase, the Moon is positioned between the Earth and the Sun, and its illuminated side is facing away from Earth. As a result, the Moon appears to be unlit by sunlight from Earth's perspective.
The correct answer is c) two different sized foam balls to represent Earth and the Moon and a light source to represent the Sun. This model would allow an observer to see the relative positions of Earth, the Moon, and the Sun, and how they change as the Moon goes through its phases.
The correct answer is d) in the order of the Moon, Earth, and the Sun in a straight line. During a total eclipse of the Sun, the Moon is positioned directly between the Sun and Earth, and its shadow is cast on Earth. In this configuration, the Moon, Earth, and the Sun are aligned in a straight line, with the Moon in the middle.
The correct answer is b) Y. If the state of Georgia is experiencing spring, then Earth must be in a position where the northern hemisphere is tilted towards the Sun. In the diagram, this is represented by position Y, where the northern hemisphere is pointing towards the Sun and the southern hemisphere is pointing away from the Sun.
The correct answer is c) Model 1 can be used to demonstrate a full moon, and Model 2 can be used to demonstrate a waning crescent moon. Model 1 shows the Moon with its illuminated side facing towards the observer, which is what happens during a full moon. Model 2 shows the Moon with a small part of its illuminated side visible, which is what happens during a waning crescent moon.
The correct answer is a) The equator receives more direct sunlight through all the seasons of the year and this produces a warmer climate than South Africa. The equator is located at 0 degrees latitude, where the Sun's rays are directly overhead throughout the year. This means that the equator receives more direct sunlight than other latitudes, which produces a warmer climate. In contrast, South Africa is located at about 30 degrees latitude, where the Sun's rays are less direct, which produces a cooler climate.
An observer standing on the Moon during a solar eclipse would see the Earth fully covered by the Moon's shadow. This is because the Moon's shadow is cast on Earth during a solar eclipse, and from the Moon's perspective, the Earth would be fully within the shadow.

Thank u a whole bunch!
Answer: 1562500 or 12500
Step-by-step explanation:
(125x10)^2 first you do 125 x 10 that's 1250 then you would have 1250^2 and that is 1562500
if this is for chem which i think it might be because of the answer options it would be 12500.

There are 2 flashlights, one flashes every 3 seconds and the other flashes every 4 seconds. If they last flashed on 10:40 am together, when are they going to flash next together? Is the answer 10:42 am??
Answer: 10:52 AM
Step-by-step explanation:
If you find the LCM of the numbers, and then add it to the last time they flashed together, you will have your answer.
Answer:
It is still 10:40:12 am
Step-by-step explanation:
First find the Lcm. That will be 12. 12 cannot be converted into minutes so it will be in seconds. So it will flash again 12 seconds later...

C^2 goes in the first box because it’s the only missing variable from the ones given.
Then c^2 goes in the second box because it hasn’t been changed.
Then 2 goes in the third box because (1/2ab x 4 = 4/2 ab = 2ab)
Then c^2 goes in the last box because it hasn’t been changed either, plus it completes the Pythagorean formula (a^2 + b^2 = c^2) so it seems the most logical
