8 0

Answer:

a) 8x+6a

b)5q+7q

Step-by-step explanation:

a) we need to combine the like(same) terms(with same variable) together

same terms: 3x and 5x

                      2a and 4a

so

3x+5x=8x

2a+4a=6a

8x+6a

b)a) we need to combine the like(same) terms together

same terms: 7p-2p=5q

                     6q+q=7q

What is the perimeter, in units, of polygon UVWXYZ? Enter your answer in the box.
nikitadnepr [17]

Given:

Consider the below figure attached with this question.

To find:

The perimeter of the polygon UVWXYZ.

Solution:

All sides and vertical and horizontal. So, we can easily find the side lengths of the given polygon by counting the boxes between two points.

From the figure it is clear that,

UV = 9 units

VW = 2 units

WX = 3 units

XY = 3 units

YZ = 6 units

ZU = 5 units

Now, perimeter is the sum of all the sides.

Perimeter=UV+VW+WX+XY+YZ+ZU

Perimeter=9+2+3+3+6+5

Perimeter=28

Therefore, the perimeter of UVWXYZ is 28 units.

Point p lies on the directed line segment from A (2,3) to B (8,0) and portions the segment in the ratio 2 to 1
Arturiano [62]

Answer:

The x-coordinate of point P is 6

Step-by-step explanation:

we have

A (2,3) and B (8,0)

we know that

Point P portions the segment AB in the ratio 2 to 1

so

AP=\frac{2}{3} AB

and

AP_x=\frac{2}{3} AB_x

where

AP_x represent the distance between the points A and P in the x-coordinates

AB_x represent the distance between the points A and B in the x-coordinates

AB_x=8-2=6\ units

AP_x=\frac{2}{3} (6)=4\ units

The x-coordinate of P is equal to

P_x=A_x+AP_x

where

A_x represent the x-coordinate of A

substitute the values

P_x=2+4=6

therefore

The x-coordinate of point P is 6
