To avoid multiplying the two numbers and then finding the cube root, find the cube root of each number first. the cube root of 27 is 3x3x3, so you can take out the three to outside of the sqrt, to get 3 cube root 18. eighteen does not have a cube root, so that's all you have to do. the answer would be 3 (cube root) 18.
Answer: B
Explanation: 10 x 5 x 12 = 600 is the same as 10 x 12 x 5 = 600, the numbers are just switched
Answer: True because when you divide both sides by 2 that would be the right equation.
Step-by-step explanation:
Hello!
To solve algebraic equation, we will need to use the acronym SADMEP.
SADMEP is similar to PEMDAS, but it is strictly used for solving algebraic equations. Expanded, it is subtract, addition, division, multiplication, exponents, and then parentheses.
Looking at SADMEP, we see that subtract/addition comes first, then division/multiplication, and then exponents/parentheses.
In our equation, our goal is to isolate the variable, "x". Since we have two constants, -3 and 11, and -3 is on the side with the variable, we can add -3 to both sides of the equation first.
Therefore, the first operation needed to solve the equation is addition.
1. Solve by differentiation (Derivative = 0 at the vertex)
dy/dx= 2x-4
0=2x-4
0=2(x-2)
x=2
when x=2 y=-5
therefore vertex (2,-5)
