Answer:
the answer is 147
Step-by-step explanation: Basicly with volume, you have to time all the sides so it would be 7x7x3, 7 is the heigh, 7 is the length and 3 is the width
You would look at number after the thousandths place to go up or down 72,000.
It should be 81 square feet.
3 yards x 9 yards = 27 yards squares.
It asks for your answer in square feet, so you multiply by 3. This is because there are 3 feet in ever yard.
27 x 3 feet = 81 square feet.
Answer:
(5x +4y)^2
Step-by-step explanation:
The first and last terms are both perfect squares, and the middle term is twice the product of their roots. That means the trinomial is the perfect square trinomial ...
25x^2 +40xy +16y^2 = (5x +4y)^2
_____
It matches the pattern ...
a^2 +2ab +b^2 = (a +b)^2
Step-by-step explanation:
here ! I used the formula area = length × width
and just some algrbric expressions solving
