Answer:
4
Step-by-step explanation:
To find the square of a number, you multiply it by itself. This means √4 * √4 gives the answer. √4 can be simplified to 2 because 2^2 is 4. So, 2 *2 gives the answer, which is 4.
Answer:
b 48
Step-by-step explanation:
it says the sides a are 3 times larger so you are trying to find the perimeter of b so you do 144 divided by 3 since it is 3 times larger.
Answer:
Step-by-step explanation:
The domain of a function is all of the values that 
can be under that specific function. In this case, we're asking what values of allow 
to exist.
In order for square roots to exist, the quantity under the square root must be greater than or equal to 
, because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for :
Solving this inequality, we get:
(Subtract 
from both sides of the inequality to isolate )
(Multiply both sides of the inequality by 
to get rid of 's coefficient)

LABC is a 30°angle point B is at (3,2)
We have 1 square with side length 8 inches, and 4 triangles with a base length of 8 inches and a height of 15.
Surface area = (8 × 8) + 4(0.5 × 8 × 15)
The first part of this equation is the area of the square
The second part is the area of a triangle, multiplied by 4 (because there are 4 triangles)
= 64 + 4(60)
= 64 + 240
= 304 in²
The total surface area is 304 square inches.
