Find the value of x. 7, 8, and 9 please!
natima [27]

Answer:

7) x= 5, 8) x= 6, 9) x= 7

Step-by-step explanation:

As per the secant theoram, if two secant intersect outside the circle then the product of the exterior secant and total length of each secant are equal.

7) ∴ (x+3)\times 3= (10+2)\times 2

opening parethesis and distributing 3 with x and 3.

⇒ 3x+9=24

subtracting 9 on both side.

⇒ 3x=15

cross multiplying

∴ x= 5.

8) (3+5)\times 5= (x+4)\times 4

Opening parethesis and distributing 4 with x and 4.

⇒ 8\times 5=4x+16

⇒ 40=4x+16

subtracting 16 on both side.

⇒ 24=4x

cross multiplying

∴ x= 6.

9) (x+5)\times 5= (6+4)\times 6

opening parethesis and distributing 5 with x and 5.

⇒ 5x+25=60

subtracting 25 on both side.

⇒ 3x=35

cross multiplying

∴ x= 7.

I am thinking of a number.
mash [69]

Answer:

21

Step-by-step explanation:

Let x be that number.

12x-216=2x-6

12x-2x=-6+216

10x=210

10x/10=210/10

x=21

21 is the number.

Why is it important to look at more than the first two numbers of a pattern to decide the rule for the pattern?
Alexxandr [17]

Answer:

This is important because, the first few numbers might seem to follow a pattern but subsequent numbers might reveal a change in the rule.

Step-by-step explanation:

When studying patterns it is important to evaluate all the figures holistically instead of drawing conclusions based on just the first few numbers because there might be a change in what we felt was obvious on close observance of all the numbers. For example, observe the pattern;

2,4,6, 10, 14, 18, 20, 22, 24

The first two numbers show the addition of two. If a person decides to add 2 to all the figures, he would be wrong because after the first three figures, he would have to add 4 to the numbers.
