Order of Operations, also known as PEMDAS (Parentheses, Exponents, Multiplication & Division, Addition & Subtraction), can help to simplify an equation by guiding you through the steps to solve it.
This is because it tells you to solve the parentheses. If there is none, but you've already done this, you solve for exponents, etc.
The progressive soling of the equation not only makes it physically shorter, but also brings you closer to the answer.
Hope this helps, and I was the brainliest! :)
Answer:
2y^2+18x
Step-by-step explanation:
4y^2 + 6x -2y^2 + 12x
=4y^2-2y^2+6x+12x
=2y^2+6x+12x
=2y^2+18x
Answer:
C. x = 3cm
Step-by-step explanation:
The formula for volume of a triangular prism is
<u>V = base * height</u>
x in this case equals height, and the base is the area of the triangular base, which is
<u>A(triangle) = 1/2 b*h</u>
= 1/2 7*10 = 35 square centimeters
Plug this back into our formula:
V = base * height
105 = 35x
Solve for x.
105/35 = x
<u>C. x = 3 cm</u>
Answer:
you are correct
Step-by-step explanation:
since there is a box in the angle, it means it's 90°, so if the 1rst angle is 30°, the other one has to be 60°
I think that Fran is correct
I think this because the problem states that 15 is the LEAST number of people in the shop, so there are MORE than 15 people
