Answer:
-20
Step-by-step explanation:
-8-12=-20
(66✖️578) ➗ 3368=55➗77
P parentheses
E exponents
M multiplication
D division
A addition
S subtraction
You would do (66✖️578) first since it is in parentheses
66✖️578=38,148
38,138➗3368=55➗77
Since there are no exponents or multiplication you would do division
38,138➗3368= 11.3236342
55➗77=0.7
11.32 does not equal 0.7
So this equation would be false
Hope this helps! :3
For this case, we have that:
- By definition, a rectangle is a parallelogram. So, we discard the first option.
- On the other hand, we have that all rectangles can not be squares, since a square has all its sides equal, while the rectangle, poir definition, no.So, we discard the second option.
- All quadrilaterals are not rectangles because there are other figures with four sides that are not necessarily rectangular. We discard the third option.
- Finally, we have that all squares are rectangles. This statement is true since squares can be rectangles with pairs of equal sides.
