Hello,

Let's r the ration

We suppose x ≠0

x=r*(x-2)==>r=x/(x-2)

x+3=r*x==> (x+3)/x=x/(x-2)==>(x+3)(x-2)=x²
==>x²+3x-2x-6=x² ==>x-6=0==>x=6

x-2=6-4=4
x=6
x+3=6+3=9
6=4*3/2
9=6*3/2

Ration 3/2
First term: 4

Can somebody please explain and answer this for me? I really don't get it.
kirill115 [55]
Answer: 12a^3
Explanation: You would get the missing side to complete the perimeter by using the pythagorean theorem so 3^2+4^2=c^2 so you would get 9+16=c^2 which would become 25=c^2. That would get you 5 as the square root of 25 is 5 so in total, it would all be 3a^3+4a^3+5a^3 which would equal 12a^3.
(^ are for exponents) I might be wrong but hopefully it helps a bit. :)

27. Write down the co-ordinates of the points where the line y = 4x - 3 cuts the x-axis <br>​
Tamiku [17]

Step-by-step explanation:

it is a line, so that is 1 point, where it cuts the x-axis.

in general that means y = 0.

so,

0 = 4x - 3

4x = 3

x = 3/4

the point, where the line cuts the x-axis is

(3/4, 0)

Can someone help me understand this?
ASHA 777 [7]

< means 'less than'. 3.5 is less than 4.5, so A is correct. Since -4.5 is NEGATIVE it is less than 0. As for C, since both numbers are negative, it would be the seemingly 'smaller' number that is actually bigger. It may help to think of the numbers on a number line. In the negatives, the numbers start to go in reverse, so the further from 0 a negative number is, the smaller it is. -4.5 IS LESS than -3.5. All answers are correct.
