Answer:
A and E
Step-by-step explanation:
x²+3x-28=0
x²+7x-4x-28=0
x(x+7)-4(x+7)=0
(x-4)(x+7)=0
x=4, x= -7

Answer:
Body Mass Index (BMI) is used to get whether the person is fit or not from the weight and height of the person.
So, the value of BMI depends on the height and weight of the person.
Thus, BMI is the dependent variable and the independent variable is weight and height.
Age can be included as other independent variables that should be included in the analysis.
For getting the value of regression we have to calculate the mean of all independent variables.
Answer:
x = 1.5
Step-by-step explanation:
Since ΔAED and ΔACB are similar then the ratios of corresponding sides are equal, that is
= 
, and substituting values
= 
, that is
x = = 1.5
The vector in component form is given by:
V = i - j.
<h3>How to find a vector?</h3>
A vector is given by the <u>terminal point subtracted by the initial point</u>, hence:
(3,-4) - (2, -3) = (3 - 2, -4 - (-3)) = (1, -1)
<h3>How a vector is written in component form?</h3>
A vector (a,b) in component form is:
V = a i + bj.
Hence, for vector (1,-1), we have that:
V = i - j.

Answer:
51
Step-by-step explanation
Given angles can break like this :
231 = 180 +51
51= 0+51
-129= -180+51
591= 360+180+51
so angles 231, -129 and 591 corresponds to the same terminal while 51 is not related to the particular quadrant . so 51 is not co-terminal with the other three angles .
