The perimeter is 2(length) + 2(width), so 2(x+5) + 2(x+4) = 42 m. In solving for x, you find 6. Plug 6 back into your length and width where x originally was, and you find your length to be 11m, and your width to be 10m. Hope this helps!

Perimeter = 2(width + height)
42 = 2(x+5 + x+4)
 2x + 9 = 21
 2x = 12
   x = 6
Width = 11
Height = 10

9) State the coordinates of the endpoints of a<br> line segment that intersects the y-axis.
eduard

Answer:

(5,4) and (3,4)

Step-by-step explanation:

A line segment has 2 end points which can be denoted as:

(x_1,y_1) and (x_2,y_2)

When this line segment intersects at y.

This means that the coordinate on the y axis is the same at both end points

i.e.

y_1 = y_2 = y

(x_1,y_1) and (x_2,y_2) becomes (x_1,y) and (x_2,y)

x1 and x2 can be any value but the y value must remain unchanged

Using the above analysis, a possible coordinate is:

(5,4) and (3,4)

Note that there are as many answers as possible as long as the coordinate pair satisfy is of the form (x_1,y)<em> and </em>(x_2,y)<em />

Take for instance, another possible pair is:

(1,-3) and (0,-3)

Xander needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items.
Aleksandr [31]

Answer:

c ≥ 56   is the REQUIRED INEQUALITY.

Step-by-step explanation:

Here, the given  question is INCOMPLETE.

Xander needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. Choose the inequality and solution to represent the number of cans, c, that Xander must still collect.

Now, here:

The number of cans Xander needed to collect = At least 120

The number of items already collected =  64

c: the number of cans, c, that Xander must still collect.

Now, the number of cans to be collected  - Cans already collected  

=  120 - 64  = 56

So, the number of can he must collect to make a TOTAL OF AT LEAST 120 cans  =  56 cans

⇒ The number of cans to be collected ≥ 56 cans

⇒c ≥ 56 cans

or, c ≥ 56   is the REQUIRED INEQUALITY.
