Answer:
Step-by-step explanation:
this is a set problem (mathematical set)
30 students played soccer
9 students played cricket and soccer
x students played neither cricket nor soccer
3x students played cricket only.
we can see that in the first set 21 appears and in the middle of the set 9 because it says 30 students played soccer adding x and 3x we have the following formula
30 + x + 3x = 50 where x is equal to 5 then ask us Determine the number of students who played cricket. then the value would be 3x + 9 = (3x5) + 9 = 24
Answer:
Center (-13,11) , radius 3
Step-by-step explanation:
The given circle has equation

We compare this to the general equation.

where (-a,-b) is the center.
This implies that;
2a=26

2b=-22
b=-11
The center is therefore (-13,11)
The radius is given by



The radius is 3
Answer:

Step-by-step explanation:
From law of indices
Answer:
2*2*3*3*5
Step-by-step explanation:
Factor 180 into prime numbers that multiply together to give 180
180 = 20 *9
= 4*5 * 3*3
= 2*2* 5 * 3*3
Now rewrite them from smallest to largest
2*2*3*3*5
