The volume of a pyramid is given by the formula
1 answer:
First I would start plugging the values into the volume equation for a pyramid.
then I would multiply both sides of the equation by 3 to get rid of the dividing
then I divide both dies by 9 to solve for B
Then I would just find combination s of numbers that when multiplied equal 28, I would just find all of the pairs then rule out the ones that dont have a difference of 3, the one(s) left should be your base dimensions.
I did this and got 4 and 7

Answer:
Step-by-step explanation:
- Option A
tells us that: When we add 5 to a variable x, we get 20. As it has a unique value for x and is completely equal to it(i.e. 15), It is an equality.
- Option B
tells us that: A variable x equals to 5. Hence, as x is unique for 5 and is wholly equal to it, it's an equality too.
- Option C
tells us that: A variable x isn't 5 but lesser than it. As we cannot equate it to 5, nor we are given the nature of the variable x, it is an Inequality.
- Option D
is an expression; It can't be called an equation or an inequality unless we relate it with another expression.
