V= A(h/3) is the formula used for finding square pyramid.
Explanation:
In the above equation V stands for volume , A stands for base area, h stands for height. For finding the volume of square pyramid we need to follow certain steps, they are as follows:
First we need to measure all the side lengths present in the base. Secondly we need to calculate the base area , where the area of one sided square is a*a , then finally we need to multiply the base area with the height of the pyramid . To find the area of the square pyramid we use the formula-
A= a2+2a root over( a2/4+h2 )
Answer:
The product is the difference of squares is 
Step-by-step explanation:
Explanation
- The given expression is (5-3 x)(5+3x).
- We have to multiply the given expression.
- Square the first term 5. Square the last term 3x.

If you reduce the fraction to a mixed number than it would be 2 2/5 but if you want to reduce it to a decimal it would be 2.4
Answer:
63
Step-by-step explanation:
Follow PEMDAS, as well as the left -> right rule.
Note that PEMDAS is the order of operations in which you should solve, and =
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction.
First, look at the problem. The problem gives you:
42 ÷ 2 x (11 - 8)
Using PEMDAS, first, solve the parenthesis:
11 - 8 = 3
Next, use the left -> right rule to solve the rest.
42 ÷ 2 x 3
(42 ÷ 2) x 3
(21) x 3 = 63
63 is your answer.
