Choose the correct description of the graph of the compound inequality: (5 points)
skad [1K]

Answer:

D

Step-by-step explanation:

Firstly,  

≤  or  ≥  means closed circle, and

<   or >  means open circle

Now, let's solve the compound inequality:

x - 1 ≤ 7

x ≤ 8

and

2x ≥ 22

x ≥ 11

This solution means "everything left of 8 (inclusive and closed circle)" and "everything right of 11 (inclusive and closed circle)"

Looking at the choices, D is right.

Please help me with this.A rectangular field is
Karolina [17]
First, let's get the perimeter of the rectangle:
P=2W+2L
P=130m+210m
P=340m
Then, let's get the area of the bigger one:
A=WL
A=65m*105m
A=6825m^2

Then let's try using a rectangle with a smaller ratio:
P=100m+240m
P=340m
Then:
A=50m*120m
A=6000m^2

If you used a square:
P=170+170
P=340
A=WL
A=85^2
A=7225

There you have it. A rectangle with a smaller area with the same perimeter.
What does it show? The smaller the difference you get from width and length, the larger the area is.

Please answer the equation in the attachment.
MariettaO [177]

Answer:

the missing value is 9.33.

Step-by-step explanation:

given,

length (l) = 3x+2

breadth (b) = 4

perimeter(P) = 68 cm

now,

P = 2(l+b)

or, 68 = 2× ( 3x+2+4)

or, 68 = 2× ( 3x+ 6)

or, 68 = 6x+12

or, 68 - 12= 6x

or, 56 = 6x

or, 6x = 56

or, x = 56/6

or, x = 9.33
