Remember to follow PEMDAS. (Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction)
4^2 = 4 x 4 = 16
16/4 = 4
4 - 4 + 16
Combine
4 - 4 = 0 + 16 = 16
16 is your answer

<h2>
Answer:</h2>
The height of the box is:
4 ft.
<h2>
Step-by-step explanation:</h2>
Let "h" denotes the height of the box.
Length of box is denoted by "l"
and breadth or width of box is denoted by "b"
We are given l=18 ft
b=8 ft.
Also we are given surface area of rectangular box= 496 ft²
As we know that the surface area of box is given by:

i.e.

Divide both side by 2.

on dividing both side by 26 we get:

Hence, the height of the box is:
4 ft.
Answer:
The next number in the sequence is 36.
Step-by-step explanation:
Consider the provided sequence.
4, 9, 16, 25
The number 4 can be written as 2².
The number 9 can be written as 3².
The number 16 can be written as 4².
The number 25 can be written as 5².
The general term of the sequence is: 
Thus, the next term will be:



Therefore, the next number in the sequence is 36.
Answer:
w = y - x is the equation to find w
Where,
w = Weight of the liquid
x = Weight of the empty can
y = Weight of the can with liquid
Step-by-step explanation:
Let
Weight of the empty can = x
Weight of the liquid = w
Weight of the can with liquid = x + w = y
x= 30 grams
w = ?
y= 47.3 grams
y = x + w
w = y - x
= 47.3 - 30
= 17.3
w= 17.3 grams
Therefore, the weight of the liquid is 17 .3 grams
