Step-by-step explanation:

Area of a Rectangle

The image shows a rectangular vegetable garden with different crops.

The rectangle has a length of L=2x+9 yards and a width of W=6x-3 yards.

The area of a rectangle is:

A = WL

[tex]A=(2x+9)(6x-3)[/tex]

Operating:

[tex]A=2x(6x)-2x(3)+9(6x)-9(3)[/tex]

[tex]A=12x^2-6x+54x-27[/tex]

Simplifying:

[tex]\boxed{A=12x^2+48x-27}[/tex]

Answer:  The probability that an event will occur is the fraction of times you expect to see that event in many trials. Probabilities always range between 0 and 1. The odds are defined as the probability that the event will occur divided by the probability that the event will not occur.

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 10 - 19 = 1 - 10 = - 9

This means the sequence is arithmetic

Answer:

the value of 7x-y is -14.

Step-by-step explanation:

When x=2 and y=4,

To find the value of 7x - y when x =2, y = 4, this means when ever you see x, put 2 in replacement, y, put 4 respectively.

7x - y = 7(2 - 4)

14 - 28

= -14.​

Correct me if I'm wrong but wouldn't even 15 be right could be a lot of things

Answer:

Any number above 14.3, example:15

Step-by-step explanation:

The question asks the sum of -14.3 and a number, (x-14.3) to be positive.

We can make it x-14.3>0

x>14.3

Answer:

Hello there:] How are you! I think that both A and C are quadrilaterals.

Step-by-step explanation:

As you might know, quadrilaterals have 4 sides because of the name quad. B has 5 sides which would make it a pentagon. Im not really sure about d since there is not really any angles. I hope this helps! :]

Answer:

This equation has one solution, if x = 0

Step-by-step explanation:

Because, you subtract 15 from both sides so: 9x + 15 - 15 = 3x + 15 - 15 which equals: 9x = 3x. if x = 0 this equation is true.

Answer:

X=0

Step-by-step explanation:

If we subtract 15 from both sides, then we can see 9x=3x. If x was 0, then the equation would be 9x0=3x0. Since 0 times anything equals 0, this equation would be true resulting in 0=0.

Step-by-step explanation:

Answer:

(-10,-7)

Step-by-step explanation:

the given equations: y=-3 and x=-10

we can substitute the x in the first equation as -10.

y=(2/5×-10)-3

simplify

y=(2/1*-2)-3

y=-4-3

y=-7

the y value is -7

we actually have the x value given as -10 (in the system)

So the answer is (-10,-7)

Hope this helps!

Answer:

Step-by-step explanation:

V of a cone V=3.14* r^2*h/3

942=3.14*r^2*9/3

r^2=942/(3.14*3)=100

r=sqrt100=10

The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.

Since there is  a volume of 942 cubic inches and a height of 9 inches

We know that

Volume of a cone V=[tex]3.14* r^2*h/3[/tex]

So,

[tex]942=3.14*r^2*9/3\\\\r^2=942/(3.14*3)=100[/tex]

r =[tex]\sqrt 100[/tex]

=10

hence, The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.

It's a triple stack

Answer:

The sets of the domain and the range of T are, respectively:

[tex]Dom \{T\} =\{-3,0,3\}[/tex]

[tex]Ran\{T\} = \{-4.-3,2,3\}[/tex]

Step-by-step explanation:

The values of the relation T that belongs to the domains correspond with the values on the x-axis and associated with the given points, whereas the range corresponds with the respective values of the y-axis. Let [tex]T = \{(x,y)|(-3,3),(3,2),(0,-3),(3,-4)\}[/tex]

The sets of the domain and the range of T are, respectively:

[tex]Dom \{T\} =\{-3,0,3\}[/tex]

[tex]Ran\{T\} = \{-4.-3,2,3\}[/tex]

The measurements that can be used to build a right-angled triangle are

[tex]6 in, 8 in, 10 in[/tex]

The measurements that can be used to build a right-angled triangle must form a Pythagorean triple. A Pythagorean triple is a set of three numbers [tex]\{x,y,z\}[/tex] that satisfy the Pythagorean relationship

[tex]x^2+y^2=z^2[/tex]

The measurements [tex]\{5 in, 7 in, 12 in\}[/tex] do not form a triple since

[tex]5^2+7^2=74\ne12^2[/tex]

The measurements [tex]\{8 in, 12 in, 14 in\}[/tex] do not form a triple since

[tex]8^2+12^2=208\ne14^2[/tex]

The measurements [tex]\{5 in, 9 in, 11 in\}[/tex] do not form a triple since

[tex]5^2+9^2=106\ne11^2[/tex]

The measurements [tex]\{6 in, 8 in, 10 in\}[/tex] form a triple since

[tex]6^2+8^2=100=10^2[/tex]

So, the last set of measurements [tex]6 in, 8 in, 10 in[/tex] can be used to build a right-angled triangle
