Answer:
Step-by-step explanation:
The volume of the pyramid is given by:
where is the area of the base and is the height.
We know that the height is:
Thus we need to find the area of the square at the base.
The perimeter of the square is:
this means that the length of the sides of the square is :
Now we can find the area of the base which the area of the square:
and finally we find the volume:
Which rounded to the nearest tenth of a cubic centimeter is:
Answer:
see below
Step-by-step explanation:
10/5
(10 over five)
Which is 2
9x² - 12x + 4
write the equation with two middle terms that multiply to give 36
9x² - 6x - 6x + 4
by factorisation
3x(3x - 2) - 2(3x - 2)
(3x - 2)²
Thus OPTION A
1 and 2 are both rational.
3 and 4 are both not.
