Answer:

x = 5.25 and it is an isosceles triangle.

Step-by-step explanation:

The perimeter of a figure it the measure of all its sides added up.

Therefore RS+RT+ST=32

By substitution:

(x+7)+(2x-3)+(x+7)=32

Combine like terms and add:

4x+11=32

Subtract 11

4x=21

Divide 4

x=5.25

After substituting the value back in, we get that RS=12.25, RT=7.5, and ST=12.25

In an isosceles triangle, two sides have the same measure.

x = 5.25 and it is an isosceles triangle.

Sara and Sam are each working on a science project in which they need to research the individual masses of the nine planets (inc
makkiz [27]

Answer:

2000 times

Step-by-step explanation:

Given

Sara:

Mercury = 3.302 * 10^{23

Saturn = 5.685 * 10^{26

Sam:

Mercury = 3.302 * 10^{29

Saturn = 5.685 * 10^{32

To determine the number of times, the mass of Saturn is greater than the mass of Mercury, we simply do the following:

Times = \frac{Saturn}{Mercury}

Using Sara's measurement; this gives:

Times = \frac{5.685 * 10^{26}}{3.302 * 10^{23}}

Apply law of indices

Times = \frac{5.685 * 10^{26-23}}{3.302}

Times = \frac{5.685 * 10^3}{3.302}

Times = 5.685/3.302 * 10^3

Times = 1.72 * 10^3

Approximate

Times = 2 * 10^3

Times = 2000

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
