The area of the given rectangle in simplest radical form is [tex]2x(\sqrt{10} + \sqrt{75})[/tex].

Perimeter is the sum of all the sides of any given 2D plane figure except circle.A circle has a perimeter or circumference of 2πr.

According to the given question we have to write an expression in simp[lest radical form that represents the area of the rectangle.

We know area of a rectangle is product of it's length and width.

Given length is = [tex]\sqrt{2x} + \sqrt{15x}[/tex] and width is = [tex]2\sqrt{5x}[/tex].

∴ The area of the rectangle will be = [tex](\sqrt{2x} + \sqrt{15x})[/tex][tex](2\sqrt{5x})[/tex] .

= [tex]2\sqrt{10x^2}[/tex] + [tex]2\sqrt{75x^2}[/tex].

= [tex]2x\sqrt{10} + 2x\sqrt{75}[/tex].

= [tex]2x(\sqrt{10} + \sqrt{75})[/tex].

Answer:

put points on (1.5, 0) and (0, -1), then draw a continuous line through them

Step-by-step explanation:

y - 3 = -2/3(x + 6)

y - 3 = (-2/3)x - 4

y = (-2/3)x - 1

0 = (-2/3)x - 1

1 = (-2/3)x

x = 3/2 = 1.5

y = (-2/3)(0) - 1

y = -1

Answer:

First Box: -10/5

Second Box = -1.25

Third Box = -0.5

Fourth Box = 0.75

Fifth Box = 3/2

Step-by-step explanation:

NOTE: I AM SAYING THIS FROM LEFT TO RIGHT

Answer:

The first box should be -[tex]\frac{10}{5}[/tex] ;

The 2nd box should be -1.25 ;

The 3d box should be -0.5 ;

The 4th box should be 0.75 ;

The 5th box should be 3/2 which is the last box left.

Answer:

0.25 (or [tex]\frac{1}{4}[/tex])

Step-by-step explanation:

As the coin is fair, there is an equal chance the coin lands on heads or tails, therefore:

Probability of heads = 0.5 (or [tex]\frac{1}{2}[/tex])

Probability of tails = 0.5 (or [tex]\frac{1}{2}[/tex])

For Bob to win, the coin must land on heads twice, To work this out, we multiply the two events together.

Probability of 2 heads = 0.5 (probability of landing heads up) x 0.5 (probability of landing heads up) = 0.25 (or [tex]\frac{1}{4}[/tex])

The answer is

A. Set X has 10 possible groupings.

there will be 36 squared.

each new step adds one more than the last step added.

f(1) = 1

f(2) = 3 = 1+2

f(3) = 6 = 1+2+3

f(4) = 10 = 1+2+3+4

the pattern is now clear hopefully

Answer:

[tex]\displaystyle \sin\theta=\frac{12}{13}[/tex]

Step-by-step explanation:

Recall that in a right triangle, sine is the ratio of the opposite side to the hypotenuse:

[tex]\displaystyle \sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]

We are actually not given the opposite side in this case. However, since we know the hypotenuse and the adjacent side, we can use the Pythagorean Theorem to find the opposite side. So:

[tex]a^2+b^2=c^2[/tex]

Let a be the adjacent side and b be the opposite side. c will be the hypotenuse.

Substitute:

[tex](5)^2+b^2=(13)^2[/tex]

Solve for b:

[tex]b=\sqrt{169-25}=\sqrt{144}=12[/tex]

So, the opposite side measures 12.

Then sine will be:

[tex]\displaystyle \sin\theta=\frac{12}{13}[/tex]

Answer:

D - T-H is negative

Step-by-step explanation:

So lets go through what we know:

M is on the left side of 0, so M is negative.

A is also one the left side of 0, so A is negative.

T is on the right side of 0, so T is postive

H is also on the right side of 0, so H is postive

Lets go through each answer and see if it is accurate or not:

The sum of M and H is postive.

With what we know, M is negative and H is postive.

Looking at the graph, we can see that M is farther to the left than H is to the right.

So this means that M is a larger negative than H is postive, meaning when we add them together, the answer will be negative, not postive.

Next we have the answer to A divided by H is negative

We know A is negative, and M also negative

Remember, a negative divided or multiplied by a negative is postive.

This is not what our answer states, as it says it should be negative.

So next off, we have the product of H and A is postive.

Product means multipication.

A is negative and H is postive

Since it is multipication, and we know a negative and postive make another negative, this would make it incorrect

The answer states it must be postive, but this is negative.

Finally we have the answer as T-H is negative.

We see that T is postive, and H is postive.

T is less than H is, so when you subtract H from T, you would get a negative.

So D is the answer

Hope this helps!

Answer:

The two numbers are 157 and 13

Step-by-step explanation:

Let x and y be the two numbers

x+y = 170

x-y =144

Add the two equations together

x+y = 170

x-y =144

-------------------

2x= 314

Divide by 2

2x/2 = 314/2

x =157

Now find y

x+y = 170

157+y = 170

y = 170-157

y =13
