By definition, a rectangle is:
Any four sided polygon (quadrilateral) that contains four right angles.
By extension, a square is:
Any rectangle where all sides are of the same, or equal, length.
<h3>So yes, a square is always a rectangle.</h3>
Step-by-step explanation:
1. you set each expression equal to 0.
x-7=0 and x+3=0
2. Next you need to get the variable by itself so you would add 7 to both sides on the first equation and subtract 3 from both sides for the second one.
3. So your answers would be x=7 and x=-3. Those are the zeros.
Answer:
35 blue shirts
Step-by-step explanation:
7 x 3 = 21
7 x 5 = 35
Step-by-step explanation:
2x - 5 = y - 5
2x = y
x = y/2
y - 3 = x + 1
Substitute the value of x here,
y - 3 = 
y - 3 = 
2y - 6 = y + 2
y = 8
Now, x = 8/2
x = 4
So, go for D part, it is the correct answer.
Good Night/Day !
