Answer:
All squares are rectangles.
Step-by-step explanation:
The requirements for a shape to be qualified as a rectangle are that there must be four sides, two sets or parallel sides, and four right (90 degree) angles. The requirements for a square are that all sides must be equal in length and that there must be four right angles. Since the requirements of a square fit under those of a rectangle, all squares are rectangles.
Answer:
The first equation answer would be 70, whilst the second equation's answer is 160. I think this would be the correct answer:
20(2) + 30(1) = 70.
20 (8) + 30(0) = 160.
Step-by-step explanation:
Basically, you would do 20(2) + 30(1) for one of the equations and 20(8) + 30(0) for the other equation. Those equations would give you the answer.
x = -25
<u>+25+25
</u>x + 25 = 0
<u>5(x+25) = 5(0)
</u>5x +125 = 0<u>

Answer:
a. -0.01 < x - 8 < 0.01
b. 7.99 < x < 8.01
c. see attachment
d. Bolt has to be greater than 7.99 mm and less than 8.01 mm to be within the margin of error of 0.01 mm.
Step-by-step explanation:
-0.01 < x - 8 < 0.01
-0.01 < x - 8 and x - 8 < 0.01
7.99 < x x < 8.01
Write this as: 7.99 < x < 8.01
On graph the 7.99 and 8.01 are very near to each other and represented via open red circle.
