What is the area of this triangle?

Answer:

The answer to this equation is 7.5

Step-by-step explanation:

What I did is started with PEMDAS:

6÷2 (1 + 2) ÷4 (4 + 5) ÷ 6

          ^               ^

         (3)            (9)

Now the 3 and the 9 are what are in the ()

6÷2 = 3... 3  (3) = 9.

9 ÷ 4 = 5.

The 9 from earlier is still in parenthesis...

Take 5 and the 9 in parenthesis and multiply (If a single number is in (), It means to multiply anyway)

5 (9) = 45

The Final Step is to divide by 6

45 ÷ 6 =  (FINAL) 7.5

I hope this helped! (:

Answer:

[tex]3\frac{3}{8}[/tex]

Step-by-step explanation:

6 ÷ 2(1+2) ÷ 4(4+5) ÷ 6 =​

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

By order of operations, parentheis comes first.

6 ÷ 2*(1+2) ÷ 4*(4+5) ÷ 6 =​

6 ÷ 2*(3) ÷ 4*(9) ÷ 6=

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

Next comes multiplication and division. Now, we can remove  the parentheis and solve from left to right.

6 ÷ 2*(3) ÷ 4*(9) ÷ 6=

6 ÷ 2*3 ÷ 4*9 ÷ 6=

3*3 ÷ 4*9 ÷ 6=

9 ÷ 4*9 ÷ 6=

27/8=

Answer:

b

Step-by-step explanation:

took the test. just trust

Add 8 positive unit tiles to both sides and create zero pairs.

The correct option is (B).

The part of mathematics that helps represent problems or situations in the form of mathematical expressions.

Given:

x + (- 8) = 3 x + 6

x- 8 = 3x +6

First,

Add 8 positive unit tiles to both sides

x- 8 + 8 = 3x +6 + 8

x= 3x +14

The, creates pair

3x-x = -14

x= -7

Hence, Add 8 positive unit tiles to both sides and create zero pairs.

Step-by-step explanation:

Answer:

Your question might have an error :( All inequality equations have to have a inequality symbol somewhere in the equation. Yours dont have one but no worries. I'll see what I can do.

Based on your equation, that is not a inequality, so therefore your answer would have been: (-5x-16)

Step-by-step explanation:

If your equation was:

(-5x-10<-6) your answer would have been: x>-4/5

(-5x-10>-6) your answer would have been: x<-4/5

(-5x>-10-6) your answer would have been: x<16/5

(-5x<10-6) your answer would have been: x>-4/5

Those are all the possible outcomes of that equation :)

Please double check to make sure that is what the question states : )

The answer is B about 28 times

Step-by-step explanation:

If he bounces the ball 20 times in 30 seconds then he bounces it once every 1.5 seconds if you multiply 1.5×6 you get 9 so you add 9 to 20 to get 29 and you choose the closest answer because is says approximately so you chose B.28

Answer:

-12

Step-by-step explanation:

10/5 = x-6/x+3

2/1 = x-6/x+3

cross multiply

2(x + 3) = x - 6

2x + 6 = x - 6

collect like terms

2x - x = -6 - 6

x = -12.

Answer:

[tex]m=8x-5-4\Delta x[/tex]

Step-by-step explanation:

We have the function:

[tex]f(x)=4x^2-5x-1[/tex]

And we want to use the difference quotient:

[tex]m=\frac{f(x+\Delta x)-f(x)}{\Delta x}[/tex]

To find the slope function.

So, let's substitute [tex]x+\Delta x[/tex] for our function. This yields:

[tex]m=\frac{(4(x+\Delta x)^2-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]

Let's square. Use the perfect square trinomial pattern. This yields:

[tex]m=\frac{(4(x^2+2x\Delta x-\Delta x^2)-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]

Distribute:

[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)-(4x^2-5x-1)}{\Delta x}[/tex]

Distribute the right:

[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)+(-4x^2+5x+1)}{\Delta x}[/tex]

Combine like terms:

[tex]m=\frac{(4x^2-4x^2)+(-5x+5x)+(1-1)+(8x\Delta x-4\Delta x^2-5\Delta x)}{\Delta x}[/tex]

The first three terms will cancel. This leaves us with:

[tex]m=\frac{8x\Delta x-4\Delta x^2-5\Delta x}{\Delta x}[/tex]

We can factor out a Δx from the numerator:

[tex]m=\frac{\Delta x(8x-4\Delta x-5)}{\Delta x}[/tex]

The Δx will cancel. So, our slope function is:

[tex]m=8x-5-4\Delta x[/tex]

And we're done!

Answer:

2x+2

Step-by-step explanation:

First you want to distribute

1/2(2x+4)

ignore the ending +x for now

Distribute 1/2 to 2x

since 2*1/2 is 1 then we get 1x, or x

next distibute 1/2 to 4

you get +2 since 1/2*4=2

so what you end up with is x+2

However, you still have the +x from the beginning

x+2+x

Imagine that each x has a one in front

1x+2+1x

now re arrange so the common factors are near each other

1x+1x+2

now add the common factors

1x+1x=2x

and finally you get 2x+2
