The perimeter of a rectangular table top is 60cm and its area is 161cm². find the length of breadth of the table top

7 or 23 centimetres

Step-by-step explanation:

{60 = 2w + 2l

{161 = wl

Setting it up like this, plugging 7 and 23 into both equations for w and l will not alter a thing. You will still get the exact same result, no matter the possible outcomes.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
