AVprozaik [17]

Answer:

dimension is 5cm * 4 cm

Step-by-step explanation:

As the plane is parallel to the base, the ratio between plane's length and width is equal to the ratio of that of the base. -> similar shape.

Moreover, it also divided the rectangular prism into 2 smaller rectangular prism. hence the plane is identical to the base. Hence, same dimension.

Step-by-step explanation:

<h3>Given expression</h3>

$2 \sqrt{3} *3\sqrt{8}$

<h3>Simplify the expression in steps as below</h3>

$2 \sqrt{3} *3\sqrt{8} =$
$2 \sqrt{3} *3\sqrt{2^2*2} =$
$2 \sqrt{3} *3*2\sqrt{2} =$
$2*6* \sqrt{3} *\sqrt{2} =$
$12* \sqrt{3*2} =$
$12\sqrt{6}$

Used properties in solution process:

$\sqrt{a^2} =a$

Solve the system of equations

ira [324]

Answer:

B) x = 2, y = 1

Step-by-step explanation:

Add the two equations to eliminate the x-variable.

(x +3y) +(-x +6y) = (5) +(4)

9y = 9 . . . . . . .simplify

y = 1 . . . . . . . . divide by 9

You can substitute this value into either equation to find x.

x + 3(1) = 5

x = 2 . . . . . . . . subtract 3

The solution is (x, y) = (2, 1).
