<h3>Answer:</h3>

-1

<h3>Step-by-step explanation:</h3>

<u>We are given:</u>

a₁ = -17    

a₁₃ = -29

<u>Solving for the Common Difference (d):</u>

We know that the formula for an AP is:

aₙ = a₁ + (n-1)d

The formula for the third term will be:

a₁₃ = a₁ + (13 - 1)d

<em>replacing the given values:</em>

-29 = -17 + (12)d

-12 = 12d                            [adding 17 on both sides]

d = -1                                 [dividing both sides by 12]

Hence, the common difference is -1

Find two numbers whos diffrence is 16 and the product is 720
antiseptic1488 [7]

Answer:

the numbers who's difference is 16 and the product is 720 is

36 &20

Explanation:

to finding numbers you have to express the equation in a quadratic equation then Factor it.

since the two numbers have a difference of 16 you can say that the first number is x and the second number is x -16 then their product is 720.

x(x-16)=720

x²-16x=720

x²-16x-720=0

(x-36)(x+20)

there are two possible value of x but since you are looking for the positive value of x, choose the positive value of x the first number is 20.

To find the second number

x-16=20

x=20+16

x=36

the second number is 36

In this question, all lengths are in centimetres.
JulsSmile [24]

Answer:

Step-by-step explanation:

AB/AC =1/2

(3x-4)/(2x+12)=1/2

2(3x-4) = 1(2x+12)

6x-8=2x+12

4x=20

X=5

AC/BC =3x-4/7x-2=22/33=2/3

AB/AC=3x-4/7x-2=22/33=2/3

AB/AC=3x-4/2x+12

6x-8=2x+12

You would get 4/5 still trying to work out the last mark
