<h2>there s a theorem called MIDPOINT THEOREM </h2>

Which means the 3rd side of the triangle is equal to 1/2 of the line drawn by joining the mid points

which means

2x-4 = 1/2×21

thus, 2(2x-4) =21

=> 4x-8 = 21

4x = 29

Answer: 1) Let's simplify step-by-step.

x22(x+y)−y2

Distribute:

=(x22)(x)+(x22)(y)+−y2

=x23+x22y+−y2

Answer:

=x23+x22y−y2

2)Let's simplify step-by-step.

The volume of a rectangular prism is 16.328 cm³. The height is 3.14 cm.

Ghella [55]

Answer:

The area of the base is = 5.2 cm²

Step-by-step explanation:

<em>First, we need to know the formula to calculate volume:</em>

$volume=height XBase area$

<em>if we change to our equations to the values we know:</em>

$16.328 = 3.14XB$

<em>Since 3.14 is multiplying B,we can pass it to divide the volume to the left side:</em>

$\frac{16.328}{3.14} =B$

<em>We calculate the operation=</em>

$\frac{16.328}{3.14} =5.2$

<em>And the answer is 5.2 cm²</em>

<em>Let me know if you have any question :D</em>
