Answer:
(2x + 5) + (x + 4) = 3x + 9
Explanation: Hope this helped you!
Simplified or Added they both equal the same thing.
Answer:
3x+9, 3(x+3)
Explanation:
The parentheses in the equation are misleading because according to the commutative property, we can add the numbers in any order we want
We can start by adding the 2x and x to get 3x
Then we can add 5 + 4 and get 9
3x+9
If you want to go even further, we can factor out a 3
3(x+3)
Where could convection currents form?

on a pavement
in the atmosphere
in outer space
Answer:
atmosphere
Explanation:
the process of warm air raising and forming clouds
Convention current happens through transfer of energy in the atmosphere.
What is convention current?Convection current involves the movement of energy from an object to another object.
Energy could move from the atmosphere through sunlight to other source such as solar panel.
Therefore, convection currents form the atmosphere.

Explain how climate can affect travel especially with airplane.
Answer:
various answers
Explanation:
In hot weather, planes can struggle to generate enough lift during take off because warm air is thinner than cool air. Some researchers warn that as the climate changes, cancellations due to high temperatures may become more common.
Every aircraft has a maximum operating temperature, which is set by the manufacturer and approved by regulators. If the air temperature exceeds that limit then planes are not permitted to take off.
Fog, snow, ice and crosswinds mean that air traffic controllers have to increase the gap between planes that are landing, reducing the number of aircraft that an airport can manage. The same weather can make it slower and more difficult for the planes to taxi between runway and terminal building.
Assess the effectiveness of using National Parks as a strategy to protect the taiga.
Need this really ASAP as this is due TODAY! Thank you so much and will award brainliest answer.
Answer:
National parks have been quite effective at protecting the wildlife, traditions, and landscape of the arctic taiga. In the US, the taiga is found around the state of Alaska, where the climate is cold, and not suitable for the growth of some plants. The taiga, however has a unique landscape, home to many species of animals, and first nation peoples, who's traditions and heritage must be preserved. One such example is in Alaska, Wrangell Saint Elias national park protects one such area of the taiga. There, wildlife have flourished due to preservation efforts to protect the taiga, and its inhabitants- which include many native americans.

Find the solution to the system of equations: x + 3y = 7 and 2x + 4y = 8
1. Isolate x in the first equation:
2. Substitute the value for x into the second equation:
3. Solve for y:
4. Substitute y into either original equation:
5. Write the solution as an ordered pair:
x = 7 – 3y
2(7 – 3y) + 4y = 8
14 – 6y + 4y = 8
14 – 2y = 8
–2y = –6
y = 3
x + 3(3) = 7
(
,
)
Answer:
x + y = 1
Explanation:
X + 3y = 7
2x + 4y = 8
2x - x = x (1x)
4y - 3y = y (1y)
8 - 7 = 1
x + y = 1

Explain how the angle-angle-side congruence theorem is an extension of the angle-side-angle congruence theorem.
Answer:
The interior angle measures of a triangle add up to 180 degrees. Thus, if you are given angle-angle-side, you can solve for the third angle measure and essentially have angle-side-angle because the given side will now be the included side.
Explanation:
In congruent triangles, 2 angles and the enclosed side of another triangle are equivalent to the similar angles and side of some other triangle, the extension of angle-angle-side.
What is angle-side-angle?The Angle-Side-Angle defines that if 2 consecutive angles as with a non-included side of one triangle are appropriate to the related 2 consecutive angles and the non-included side of the other triangle, then the 2 triangles are congruent.
This congruent triangle is called as the angle-side-angle, and they form, the extension of angle-side-angle congruence theorem.
A triangle is measured by the inferior angle that add up to 180 degrees. Thus, in given angle-angle-side, solve for the 3rd angle measure and fundamentally have angle-side-angle, as the given side will now be the enclosed or included side.
Therefore, it is called as the extension of angle-side-angle congruence theorem.

Describe About Earthquakes answer ASAP for the brainliest
Answer:
Earthquakes are caused by fault lines.
Explanation:
The continents are on massive tectonic plates the are constantly shifting because of the movement of magma underneath them. When the tectonic plates rub against each other, or collide with each other, it creates movement that we know as earthquakes. The reason why we feel earthquakes is because of the sudden energy release which causes seismic waves. One famous fault if the San Andreas fault, located in California. That is the reason why earthquakes are common in California (because it is located right next to a fault line).
Answer:
Explanation:
Earthquakes are rubbed against eachother and can cause lots of damage to the environment and people, the earthquakes in california can be very dangerous and can hurt a lot of people due to the mass population and density
