(x+4)(x+6)=0
x = -4, x=-6
The answer is C.
Answer:
The ratio of perimeter of ABCD to perimeter of WXYZ = 
Step-by-step explanation:
First, we have to determine the multiplicative factor of the dimensions for both figures.
Considering sides AB and WX,
multiplicative factor = 
= 1.5
So that:
XY = 6 x 1.5 = 9
YZ = 7 x 1.5 = 10.5
ZW = 7 x 1.5 = 10.5
Perimeter of ABCD = 6 + 7 + 7 + 8
= 28
Perimeter of WXYZ = 9 + 10.5 + 10.5 + 12
= 42
The ratio of the perimeters of the two quadrilaterals can be determined as;
ratio = 
= 
=
The ratio of the perimeter of ABCD to perimeter of WXYZ is .
Answer:
Yes. Have the same distribution.
Step-by-step explanation:
Given that X is a random day of the week, coded so that Monday is 1, Tuesday is 2, etc. (so X takes values 1, 2,..., 7, with equal probabilities).
Y is the next day after X
So Y can be written as X+1
But since highest value is 7, we can write
Y = X+1 mod 7
i.e. whenever X=7, Y= 8= 1 again.
Thus Y can take values as
Y 1 2 3 4 5 6 7
P(Y) = P(X+1) = 1/7
i.e. Y also has the same distribution as X
<span>In our equations, you can use the generic form of y = mx + b to determine the y-intercept for the function, with b equal to the y-intercept. For g(x), b =2 and for f(x), b=-1. These values are the y-intercepts for the functions. Based on this, the y-intercept of f(x) is 3 units below the y-intercept of g(x). We know this because we can subtract the b value from f(x) from g(x) to get the difference. Difference = 2 - (-1) = 3.</span>
