Answer: 7x + 3

Step-by-step explanation: To simplify, notice that there are two terms that contain an <em>x</em> in this problem and they are 2x and 7x.

Since both terms contain an <em>x</em>, you can add them together.

So 7x + 2x simplifies to 9x.

Now we have 7x + 3.

Now, you might think that 7x + 3 simplifies to 10x but that's not the case.

7x + 3 can actually not be simplified.

In order for you to be able to add two terms together, you need to have variables that are exactly the same.

Find the equation of line that passes through the points: A(2,3) and B(4,6)

valentinak56 [21]

Answer:

Step-by-step explanation:

Hello : let A(2,3) B(4,6)

the slope is : (YB - YA)/(XB -XA)

(6-3)/(4-2) = 3/2

an equation is : y=ax+b a is a slope

y = (3/2)x +b

the line through point (2,3) : 3 = (3/2)(2)+b

b = 0

the equation is : y =(3/2)x

kaheart [24]

Answer:

$Volume = 2000\ in^3$

Step-by-step explanation:

Given

Dimension: 10in by 20in by 10in

Required

Determine the capacity of the aquarium

This question implies that, we calculate the volume of the prism and this is calculated by multiplying the dimensions of the aquarium. i.e.

$Volume = Length * Width * Height$

Substitute values for the dimensions

$Volume = 10 * 20 * 10$

$Volume = 2000\ in^3$

Hence, the volume of the aquarium is 2000 cubic inches
