Answer:
B
Step-by-step explanation:
First simplify the first term to get
10y^4
then multiply 10y^4 by 4 square root 6y^3
40y would be all you needed to get answer
Answer:
40y^5√6y (B)
Step-by-step explanation:
Let's multiply 2√25y^8 * 4√6y^3:
8√150y^11 (When you multiply exponents with the same base, you can just add the exponents and keep the same base:
Ex. 4^5 * 4^9 = 4^14)
Let's simplify 8√150y^11
√150 = 5√6
√y^11 = y^5√y
So our final answer would be:
40y^5√6y
Answer: 44g is the answer
Answer:
Step-by-step explanation:
-3v + 11 = -8v + 51
-3v + 8v = 51 - 11
5v = 40
v = 40 : 5
v = 8
--------------------------
-3(8) + 11 = -8(8) + 51
-24 + 11 = -64 + 51
-13 = -13
B . in an observational study, the researchers do not control treatment, and in an experiment, they do.
C . in an experiment, cause-and-effect is analyzed, and in an observational study, it is not.
D . in an experiment, one group is studied over a short period of time, and in an observational study, the group is studied over a longer period of time.
Answer: (b) in an observational study, the researchers do not control treatment, and in experiment, they do.
Step-by-step explanation: In an observational study, only one group is studied, but in an experiment, more than one, may be two, three, etc. are studied, so option (A) is not correct. In an observational study, researchers control treatment but in experiment they do not, and so, option (B) is also incorrect. Option (D) is not correct, because a group is studied over a longer period of time in an experiment and the group is studied over a short period of time in observational study. The only correct option is (C) because cause and effect is studied in an experiment and are not studied in an observational study.
Hence, (C) is the correct option.

b
Step-by-step explanation:

5(-3x - 2) - (x - 3) = -4(4x + 5) + 13
Problem 2: Simplify the expression
2(a -3) + 4b - 2(a -b -3) + 5
Problem 3: If x <2, simplify
|x - 2| - 4|-6|
Problem 4: Find the distance between the points (-4 , -5) and (-1 , -1).
Problem 5: Find the x intercept of the graph of the equation .
2x - 4y = 9
Problem 6: Evaluate f(2) - f(1)
f(x) = 6x + 1
Problem 7: Find the slope of the line passing through the points (-1, -1) and (2 , 2).
Problem 8: Find the slope of the line
5x - 5y = 7
Problem 9: Find the equation of the line that passes through the points (-1 , -1) and (-1 , 2).
Problem 10: Solve the equation
|-2x + 2| -3 = -3
Simplifying -2x + -4y = 9 Solving -2x + -4y = 9 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4y' to each side of the equation. -2x + -4y + 4y = 9 + 4y Combine like terms: -4y + 4y = 0 -2x + 0 = 9 + 4y -2x = 9 + 4y Divide each side by '-2'. x = -4.5 + -2y Simplifying x = -4.5 + -2y13/18
