Answer:

they have different answers

Step-by-step explanation:

X - 13 = 4 and 13 - X = 4

for x- 13 = 4

x=4+13=17

x=17

for 13 - x = 4

13-4-x=0

9-x=0

9=x

x=9

we conclude that the dimensions and area of the scaled figure are:

l₂ = 48 in
w₂= 32in
A₂ = 1,536 in^2

How to find the dimensions of the large rectangle?

First, we know that the large rectangle is the smaller rectangle rescaled, with a scale factor k = 4.

This means that each dimension of the smaller rectangle must be multiplied by 4 to get the correspondent dimension on the larger rectangle.

The dimensions of the smaller rectangle are:

l₁ = 12in

w₁ = 8in

Then the correspondent dimensions of the large rectangle are:

l₂ = 4*12in = 48 in

w₂= 4*8in = 32in

Now, the area of the large rectangle is given by the product between the two dimensions, we will get:

A₂ = 48in*32in = 1,536 in^2

Then, we conclude that the dimensions and area of the scaled figure are:

l₂ = 48 in
w₂= 32in
A₂ = 1,536 in^2

In logic, a condition that must be satisfied for a statement to be true, but does not in and of itself make it true. Sufficient

Archy [21]

Answer:

Correlation

Step-by-step explanation:

This can be explained if we consider the case of correlation as in correlation this condition can arrive where a statement should be satisfied to be true when does not in or make it true itself.

Correlation is indicative of the degree to which there is a fluctuation in one more varying values together. The increase or decrease in the value is indicated by the positivity or negativity of the correlation respectively where the correlation itself does not make it true or is true in itself.
sufficient and necessary conditions are fulfilled only when one value needs to be true or false for the other to be true or false respectively.

Causality also known as causation is the effectiveness or potency in which one process or a cause, leads to the generation of of another process or an effect, where cause and effect are partially dependent on each other.
