<h2>Greetings!</h2>

Answer:

{x | x > -4}

Step-by-step explanation:

The direction of the < or > sign only changes when numbers are multiplied or divided by negatives.

Because to simplify 9x > -36 you only need to divide by 9, the sign stays the same and the numbers are simply divided:

\frac{9x}{9}  > \frac{-36}{9}

x > -4

So the solutuon set would be:

<h3>{x | x > -4}</h3>

A rectangular garden's length is 5 feet longer than its width. If its perimeter can be represented using the function P(x) = 4x
Ainat [17]
Let
y----------> the length of the rectangle
x---------> the width of the rectangle
P--------> perimeter of a rectangle

we know that
P=38 ft
[P]=2*[x+y]------> 38=2*[x+y]------> equation 1
y=5+x-------> equation 2
<span>substitute 2 in 1
</span>P=2*[x+(5+x)]---------> P=4x+10---------> the given equation
4x=38-10--------> 4x=28----> x=7 ft
y=5+7-----> y=5+7------> y=12 ft

the answer is
the width is 7 ft

one angle of an isosceles triangle measure 140 degrees. which other angles could be in that isosceles triangle?
Scilla [17]

Answer:

20!

Step-by-step explanation:

Isosceles triangles have 2 angles are the same. Since we can't do 140, because interior angles of a triangle equal 180, then we need to subtract 140 from 180. 180-140=40. 40/2 because of 2 angles=20. 20 is the angle.
