− 3x − 30 = 5x + 18

1 answer:

6 0

In the second and third line, where 3x was taken off both sides. On the left -3x-3x should have given -6x.
3x should have been added to both sides in order to cancel out the -3x

A given rectangle has an area of 20 ft.². What is the length for various widths?

pychu [463]

well, the area of a rectangle is simply length * width, just that product, this one has an area of 20.

now, if we do a quick prime factoring of 20, we get 20 = 2 * 2 * 5.

so we can shuffle around those numbers like

$\bf \stackrel{length}{\stackrel{(2\cdot 2)}{(4)}}\times\stackrel{width}{(5)}\qquad\qquad\qquad \stackrel{length}{(2)}\times\stackrel{with}{\stackrel{(2\cdot 5)}{(10)}}$

state the inverse, contrapositive, and converse of each conditional statement. then indicate whether the inverse, contrapositive

djyliett [7]

The inverse is the false and the Converse is the true.

According to the statement

We have to find that the contra positive, and converse are true.

So, For this purpose, we know that the

A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences. For this conditional statement, P is called the hypothesis and Q is called the conclusion.

From the given information:

if 3 is a prime number then 5 is an even number.

Then

a) Inverse: If 3 is not a prime number, then 5 is not an even number. (True)

Contra positive: If five is not an even number, then 3 is not a prime number. (False)

Converse: If 5 is an even number, then 3 is a prime number. (True).

And

b) if 7 < 5, then 5 < 3

This statement is the false because the first statement is the false.

So, The inverse is the false and the Converse is the true.
