X = 12
Use the Pythagorean Theorem.
13^2 = 5^2 + x^2
169 = 25 + x^2
Subtract 25 from both sides.
144 = x^2
Take the square root.
12 = x
1) 4/5 + 4/5 = 1 3/5
2) 4/5 + 2/5 + 2/5 = 1 3/5
Answer: 8

Answer:
y = 4
Step-by-step explanation:
An exponential function in standard form is
y = a 
Use ordered pairs from the table to find a and b
Using (0, 4), then
4 = a
( note that
= 1 ), so
a = 4, then
y = 4 
Using (1, 8)
8 = 4
= 4b ( divide both sides by 4 )
b = 2
y = 4
← represents the values in the table
Answer:
192
Step-by-step explanation:
Well if the first rectangle is 72 and 56, then we can find the area of that by multiplying length times width which would be 4032, so that would be the area of the second one. then we divide 4032 by 21, which is 192.
P.S, This is my first question answered, so if im wrong please let me know, thank you!
