Answer:

8x-7

Step-by-step explanation:

5(x-2)+X=6(x+3)-4x

You would need to use the distributive property first to distribute 5 and 6.

5x-10 + X= 6x+3-4x

You would then need to combine like variables.

5x+x+6x-4x=8x

-10+3=-7

Then you would just recreate the expression.

8x-7

Vladimir [108]

Given:

In △ABC is a right angle triangle.

AC is 6 units longer than side BC.

$Hypotenuse=2\sqrt{17}$

To find:

The length of AC.

Solution:

Let the length of BC be x.

So, Length of AC = x+6

According to the Pythagoras theorem, in a right angle triangle

$Hypotenuse^2=Base^2+Perpendicualar^2$

△ABC is a right angle triangle and AC is hypotenuse, so

$(2\sqrt{17})^2=(x)^2+(x+6)^2$

$68=x^2+x^2+12x+36$ $[\because (a+b)^2=a^2+2ab+b^2]$

Subtract 68 from both sides.

$0=2x^2+12x+36-68$

$0=2x^2+12x-32$

$0=2(x^2+6x-16)$

Divide both sides by 2.

$x^2+6x-16=0$

Splitting the middle term, we get

$x^2+8x-2x-16=0$

$x(x+8)-2(x+8)=0$

$(x+8)(x-2)=0$

$x=-8,2$

Side cannot be negative, so x=2 only.

Now,

$AC=x+6$

$AC=2+6$

$AC=8$

Therefore, the length of AC is 8 units.

How do you divide and multiply and algebra and fractions help please

ss7ja [257]

So divide factions ex: 6/2 divide 3/2 will bring down the first faction 6/2 then the always flip the second faction 2/3 to make it 2/3 the you have 6/2 divide 2/3, now you multiple 6/2 times 2/3 so how many times does 3 go in6 so the 3 will be 1 and the 6 will be 2 now 2 and 2 both will come 1 because 2 goes in both of them 1 time and the answer is 2/1
