Answer:
Yes because it fits the Pythagorean Theorem
Step-by-step explanation:
see: 5 ^2 = 25
and 3^2 + 4^2 = 9 + 16 = 25
25 = 25
so it is
THIS IS EASY. I don't have a calculator on me so bare with me.
1.) 7x - 9 = -4x + 90
7x +9. = -4x. + 9
7x. = -4x. 99
+4x = +4x. + 99
11× = 99
÷ 11. ÷ 11
X = 9
U can solve the rest. Are you serious?

Answer:</h2>
To solve this problem we will use Heron's formula:

Where
are the side lengths of the triangle and
is the semiperimeter (half the perimeter of the triangle). We know that:

Also:

Finally:

Answer:
= 9000³
Step-by-step explanation:
*Volume of the bigger box :-
20 × 20 × 20 = 8000
*Volume of the smaller box :-
10 × 10 × 10 = 1000
Therefore, volume of the aquarium :-
= 8000 + 1000 = 9000³
