What value goes in box A?

Mathematics
1 answer:
marishachu [46]3 years ago
5 0

Step-by-step explanation:

Hello!

For this you multiply the numbers that intersect at that box

Box A 2x and 4 intersect

2x * 4 = 8x

Box B 3 and 4 intersect

3 * 4 = 12

Box C 2x and x intersect

2x * x = 2x^{2}

Box D 3 and x intersect

3 * x = 3x

To solve this we put all these together

2x^{2} +3x+8x+12

Combine like terms

2x^{2} +11x+12

Hope this helps!

Solve the system using elimination.<br> 2x + 18y = -9<br> 4x + 18y = -27
Elan Coil [88]

First, let's cancel out the x by multiplying 2x + 18y = -9 by -2.

-2 ( 2x + 18y = -9) = -4x -36y = 18

Then, we combine the two equations.

-4x + 4x = 0

18y - 36y = -18y

-27 + 18 = -9

Our new equation is -18y = -9.

Now, divide both sides by -18.

-18y / -18 = y

-9/ -18 = 1/2

y = 1/2

We can plug in a value for y since y = 1/2 now.

Let's use 2x + 18y = -9

Plug in y.

2x + 18(1/2) = -9

2x + 9 = -9

Then, subtract 9 from both sides.

2x = -18

Divide by 2.

2x/2 = x

-18/2 = -9

x = -9

Lastly, we can plug in both x and y values to see it works.

2(-9) + 18(1/2) = -9

-18 + 9 = -9

Therefore, the values of x and y does work.

x = -9

y = 1/2

A motorcycle zoomed along the freeway, traveling 10 meters in
Hoochie [10]

The speed of the motorcycle will be 30 meters per second.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

A motorcycle zoomed along the freeway, traveling 10 meters in 1/3 of a second.

Then the speed of the motorcycle will be

Speed = 10 / (1/3)

Speed = 10 x 3

Speed = 30 meters per second

The speed of the motorcycle will be 30 meters per second.

More about the speed link is given below.
