Rates are usually written in unit because it shows you the amount of something per one of the thing it is being compared to (EX: 5 oz/ 1 pig)
Answer:
L=22feet
w=19feet
Step-by-step explanation:
Perimeter(p)=82
Length=(L)
Width=(w)
P=2L+2w
2L+2w=82 .......(1)
L-w=3........(11)
From (11) L=3+w
Substitute L=3+w in (1)
2(3+w)+2w=82
Clearing brackets
6+2w+2w=82
6+4w=82
Collect like terms
4w=82-6
4w=76
w=76/4
w=19
Substitute w=19 in (11)
L-19=3
Collect like terms
L=3+19
L=22

Answer:
discrete
Step-by-step explanation:
This graph is discrete. A discrete graph has separate values, which are represented by multiple unconnected points. In continuous graphs, the values are all connected to each other. If this graph was continuous, then we would see a line rather than separate dots. The graph can also not be neither continuous nor discreet because it passes the vertical line test, meaning that it is a function.
Hope this helps :)
Question 1)
there’s 180 degrees in a triangle
70 + 70 = 140
180 - 140= 40
A= 40
question 2)
there’s only one line of symmetry, down the middle
