Answer:

They are simplified in hopes of finding like terms so we can add or subtract them.

When multiplying or dividing we can multiply or divide the numbers under the radicals before simplifying

Step-by-step explanation:

√8 and √32 are not like terms, so we can't simply add or subtract them.  We first want to reduce them down as much as possible...

√8 + √32  

   √8 = (√4)(√2) = 2√2

       √32 = (√16)(√2) = 4√2

So √8 + √32 is the same as 2√2 + 4√2  

These are now like terms since they share a common number under the radical sign.  

2√2 + 4√2 = 6√2

Multiplying:   (√2)(√2) = √4 = 2

Dividing:  (√16)/(√4) = √4 = 2

                or   (√16)/(√4) = 4/2 = 2

Juanita is cutting a piece of construction paper in the shape of a parallelogram. Two opposite sides of the parallelogram have l
Tamiku [17]

Answer:

 Second option: 4 cm and 7 cm.

Step-by-step explanation:

A Parallelogram is defined as a type of Quadrilateral, whose opposite sides are parallel and have equal lenght.

Since the opposite sides (5n-6)cm and (3n-2)cm have the same lenght, then:

5n-6=3n-2

Now you have to solve for "n":

Add 6 to both sides of the equation.

Subtract 3n to both sides of the equation:

5n-6+(6)-(3n)=3n-2+(6)-(3n)\\5n-3n=-2+6\\2n=4

Divide both sides of the equation by 2:

\frac{2n}{2}=\frac{4}{2}\\\\n=2

To know the lenght of two adjacent sides, susbtitute n=2 into the third side (2n + 3)cm and into one of the the sides that are opposite to eache other. Then:

(2(2)+3)cm=7cm\\\\(5(2)-6)cm=4cm
