State the property that justifies the statement: If 4x + 9 = 15 and X=2y + 1, then 4(2y+1) + 9 = 15.
Distributive Property
Multiplication Property of Equality

Substitution Property of Equality

Substitution property of equality

Step-by-step explanation:

Given

and

Then

Required

State the property

From the list of options, (d) answers the question.

This is so because:

Substitution property of equality states that

If then

In other words, both can replace one another.

So if , then 2y + 1 can be substituted for x in

So:

 becomes

Hence, it is substitution property of equality

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
