Commutative property because 6•4=4•6 is communative property
Yes 28/30 is bigger than 4/5.
Answer:
A = 20.5 sq units
Step-by-step explanation:
you have the height of 5 but need to figure out the base
we can use the Pythagorean Theorem two times to find it
1) a² + 5² = 7²
a² = 49-25
a =
=
·
= 2
2) b² + 5² = 6²
b² = 36-25
b = 
Base = 2
+ 
A = 1/2 x 5· (2
+
)
A = 2.5 · (2
+
)
A = 2.5(8.2)
A = 20.5
