Answer:
1. An Experimental
2. Dependent
3. Independent
Step-by-step explanation:
Considering the description of how the research was carried out, it can be concluded that This study is an example of AN EXPERIMENTAL study. This because the researcher is trying to study the effectiveness of a new drug for lowering cholesterol
The difference in cholesterol level is the DEPENDENT variable. This is because the difference in cholesterol level is what the researcher wants to determine.
The treatment with a drug or placebo is the INDEPENDENT variable. This is because this is what the researcher manipulates to determine the difference in cholesterol level which is the dependent variable in this experimental study.

<em>These triangles are congruent, it means all sides are equal.</em>
<em>We equate the sides that are equal and we get this two equations:</em>
x = y + 1 -------------- (1)
x + 3 = 3y -------------(2)
Sub (1) into (2)
(y + 1) + 3 = 3y
y + 1 + 3 = 3y
3y - y = 3 + 1
2y = 4
y = 2 -------------- sub back into (1)
x = y + 1
x = 2 + 1
x = 3
Ans: x = 3, y = 2
Answer:
Because of AAS
firstly, the hypotenuse
secondly, the right angle
thirdly, the acute angle
Step-by-step explanation:
Hello,
x^3+64=0
==>(x+4)(x²-4x+16)=0
==>x=-4 because x²-4x+16 is not factorable in R.
