You just put the numbers in the formula 3x30 = 90 km
Answer:
Solution of the system is (2,1).
Step-by-step explanation:
We are given the following system of equation:

We would use the elimination method to solve the following system of equation.
Multiplying the second equation by 4 and adding the two equation we gwt:

Solution of the system is (2,1).
Answer:
figure 3: 17 cubes.
figure 4: 21 cubes.
figure 5: 25 cubes.
Step-by-step explanation:
Let the nth figure be represented by f(n).
also we are given f(n+1)=f(n)+4.
The number of cubes used in figure 1 i.e. f(1) is 9.
number of cubes used in figure 2 i.e. f(2) is 13
Now we have to find the number of cube used in figure 3, figure 4 and figure 5.
number of cubes in figure 3 i.e. f(3)=f(2)+4=13+4=17.
number of cubes in figure 4 i.e. f(4)=f(3)+4=17+4=21.
number of cubes in figure 5 i.e. f(5)=f(4)+4=21+4=25.
PI r SQUARED SOUNDS LIKE AREA TO ME,
IF YOU NEED A CIRCUMFERENCE JUST USE PI d
You never heard that song? XD
So do Pi x the radius, squared (12.25^2)
-round to 1 decimal place(?)
