Answer:

Step-by-step explanation:

You have so many questions here that doing one or two of them will hardly matter since are many more present.

Pick number 3 to start with

The left and right part of the cross will contain two numbers that multiply to 16. The numbers should be 8 and 2. Are 8 and 2 the right answers. ? They should be, because the bottom part of the cross is 8 and 2 added which is 10.

So the answer is left is 8, right is 2, bottom is 10. The 8 and 2 can be switched.

Try number nine next.

You need two numbers that multiply to 72 and that add to 18. You could use 8 and 9, but they done work. They do multiply to 72 but they only add to 17 which is not good enough.

Try 12 and 6. That looks much better. 12 * 6 does multiply to 72 so we're good so far. But the clincher is that 12 and 6 add to 18 which makes the answer right.

bottom = 12 + 6

left = 12

right = 6

Top = 12*6 = 72

Note: do all the ones that have no minus signs. When you have done that, come back and ask how to do a question that has a minus.

Chord AC intersects chord BD at point P in circle Z.
Alik [6]

In this question, we have to use the intersecting chord theorem, and the formula which is

AP * CP = BP * DP

In the given circle, values of AP, CP and DP are 12m, 6m and 5m respectively .

Substituting the values in the formula, we will get

12*6 = 5BP

Dividing both sides by 5

BP = \frac{72}{5} = 14.4 m
