Answer:
A = 16 13unit^2 + 9unit^2 = 5 √10 = 15.8 = 16
Step-by-step explanation:
For Pythagoras we square route
= x^2 = 13^13 + (one of the closer squares for x elimination)
x= 169 + 81 169 + 100 169 + 49 169+64 169 + 121
x = 250 or 269 or 218 or 233 or 290
x= 5√10 or 15.8 or √269 269 or √218 2.8 or √233 or 2.33 ( or √290 = ( √48+2) or 2.9
Noreen made 8 and 2/3 cups which after solving becomes 8.666
now the guest ate 3/4 which means 3/4 of 8.66 which is 6.50 which means the guest ate 6 1/2 cups
-4²
Any number repeatedly multiplied by itself has an exponent. so (-4)(-4) has an exponent of 2 while (-4)(-4)(-4) would have an exponent of 3 and be written as -4³.
Also extra tip: Negative numbers multiplied by a negative number will always be positive.
