Answer:
(x + 8) (x - 8)
Step-by-step explanation:
To factorise the expression follow the steps:
Think the factorising means you want like:-
( x + _ ) ( x + _ )
Now, add the numbers to get 0 & multiple together to get -64
-64 = 8 x -8
8 + -8 = 0
Now fill the numbers in the factorising mean which will give you,
( x + _ ) ( x + _ ) --> ( x + <u>8</u> ) ( x - <u>8</u> )
Therefore, the answer will be: ( x + <u>8</u> ) ( x - <u>8</u> )
I hope this will help you :)
Answer:
<em>X can equal 22.5 </em>
Step-by-step explanation:
I've set up the equation below:

With this equation, as any addition equation goes, we assume it to be like this:
A + B = C
so
C - A = B
that means,

The easiest thing to do is to make 2/3 have the same denominator as 8/9, we do this by...

So...

We now know that 5 over x equals 2 over nine. We can determine x by cross multiplying as follows:

So, x is 22.5, making the equation indeed solvable.

2/3y- 2/5 =5
add 2/5 on both sides:
2/3y = 5 + 2/5
Combine the fraction:
2/3y = 5 2/5
Write in improper Fraction:
2/3y = 27/5
Divide both sides by 2/3:
y = 27/5 ÷ 2/3
Change divide fraction to multiplication fraction:
y = 27/5 x 3/2
y = 81/10
Write in mixed number:
y = 8 1/10
Answer: y = 8 1/10
