Answer:
10⁴ seconds
Step-by-step explanation:
Given that,
A person breathes
in about cubic meters of air per second.
We need to find time taken to breathe 2.5 cubic meters of air.
In 1 sec =
m³ of air breathe
Let in x seconds, 2.5 m³ of air taken by the person.

Hence, in 10⁴ seconds 2.5 m³ of air is taken by the person.
Answer: The factorization of

The factors of
are 28 and 1+2t+w.
Step-by-step explanation:
The given expression : 
To factorize it, we need to find the common factor.
As 56 can be written as 2 x 28.
So, the above expression would become

Now, taking 28 as common from all the terms, we will get

Thus, the factorization of

And the factors of
are 28 and 1+2t+w.
subsitute x = 6 into the lengths
3(6) -7
18 - 7
11cm
(6) + 5
11cm
therefore it is a square when x = 6 because the sides are all equal
Answer:
273x
Step-by-step explanation:
-7x(-8²+25)
8²=64
-7x(-64+25)
-64+25=-39
-7x(-39)
-7×-39=273
273x

Answer:
(x +4)^2 +(y +8)^2 = 64
Step-by-step explanation:
The equation of a circle with center (h, k) and radius r is ...
(x -h)^2 +(y -k)^2 = r^2
The circle centered at (h, k) = (-4, -8) with radius 8 has equation ...
(x +4)^2 +(y +8)^2 = 64
