Answer:

3*x + 3*8 = 42 simplified as 3x + 24 = 42

Step-by-step explanation:

The correct first step in solving the equation is to apply the distributive property. Order of operations states to perform operations in this order, PEMDAS, left to right. Some operations can be applied at the same time left to right through the equation such as multiplication and division as well as addition and subtraction. Since 3 is being multiplied into parenthesis, this needs to be applied first using the distributive property.

3(x+8)=42

3*x + 3*8 = 42

3x + 24 = 42

You can continue to solve using inverse operations.

3x = 18

x = 6

Here are the two arguments you will be debating: Argument A: There is a need for students to understand and be able to construct

igomit [66]

The appropriate response is B. The contend that there is no requirement for understudies to utilize a compass and straightedge, and every single geometric development ought to be finished utilizing a drawing program is the wrong explanation since the power to control drawing programs is just open in a few spots. Not everyone would have the capacity to learn geometry in light of the fact that not everyone can have power. Everyone on the planet would not have a similar opportunity to learn geometry if just drawing programs had the information that we have today.

A=bh; A=48, b=12 what is h equal?

OleMash [197]

1. Plug in numbers
•48=12h
2. Divide 48 by 12
•48/12=12h/12
3. 12/12 cancels out, and 48/12=4

h=4
