3x^(2)+4x-3x-5-2=0
3x^(2)+x-7=0
Discriminat= b^(2)-4ac= 1^(2)-4(3)(-7)= 1-12(-7)=1+84=85
The discrimination is bigger than 0 (delta>0) therefore there are 2 real solutions

1 of 5<br>What is the nth term rule of the linear sequence below?<br>2,5, 8, 11, 14, ...<br>w<br>Tn​
Alika [10]

Answer: 3n-1

The difference between each of the numbers is 3.  This means that we have 3n.

If we assume that for the first number n=1, then 3*1=3, but the value we have is 2. This means that we must subtract 1 to get from 3 to 2.

One half of the sum of a number and 10
garri49 [273]

So, sum of a number and 10 can be written as x+10.

Now the given statement is "One half of the sum of a number and 10 ".

So, one half of x+10 can be written as \frac{1}{2} (x+10)

HELP IVE BEEN STUCK ON THIS FOREVER
jeyben [28]

Step-by-step explanation:

the figure I've circled is similar to yhe figure shown because when we compare the measurements of the length and breadth of both rectangles, we can see that both the rectangles have the see me measurements, 3ft and 7ft. The only difference however, is that the figures have been rotated differently, the figure shown is kept vertically, on the other hand, the figure I've circled is rotated horizontally.

hope that helps...
