Answer:
5x
Step-by-step explanation:
Because the inequality sign means it greater and if it turned around than it means it less than and the = sign means it equal to
Answer:
c. 10
Step-by-step explanation:
Eliminate parentheses using the distributive property.
3(b+4) -2(2b+3) = -4 . . . . given
3b +12 -4b -6 = -4 . . . . . parentheses eliminated
-b +6 = -4 . . . . . . . . . . . . collect terms
-b = -10 . . . . . . . . . . . . . . subtract 6
b = 10 . . . . . . . . . . . . . . . . multiply by -1
_____
The rules of equality require that any operation you perform on one side of the equal sign must also be done on the other side. So when we say "subtract 6", we assume you know that means "subtract 6 from both sides of the equation", for example.
The actions that prove that the quadrilateral is a parallelogram are:
- Use the slope formula on each side of the quadrilateral and show that opposite sides have the same slope.
- Use the distance formula on each side of the quadrilateral and show that opposite sides have the same length.
<h3>
Quadrilaterals</h3>
Quadrilaterals are polygons that have four sides and four corners
<h3>Parallelograms</h3>
Parallelograms are quadrilaterals that have parallel and congruent opposite sides
For the quadrilateral to be a parallelogram, then the opposite sides must be congruent.
This can be proved using the distance formula
Also, for the quadrilateral to be a parallelogram, then the opposite sides must be parallel.
This can be proved using the slope formula
Hence, the possible actions are (a) and (b)

Answer:
It is b
Step-by-step explanation:
Step-by-step explanation:
Step 1: Set up the formula for the surface area of a regular pyramid.
SA = 
where :
- SA equals the total surface area of the pyramid,
- p equals the perimeter of the base,
- h equals the slant height of the pyramid
- B equals the area of the base.
Step 2: Plug the perimeter of the base into the formula
you can calculate the perimeter by multiplying the length of one edge by the number of edges.
Step 3: plug the value of the slant height into the formula (it is not the perpendicular height)
Step 4: find the area of the base (depend on the shape of the base)
Hope it will find you well.
