If xy=0 assume that x and y=0
so
(2x-8)(7x+5)=0
assume
2x-8=0 and 7x+5=0
solve each
2x-8=0
2x=8
x=4
7x+5=0
7x=-5
x=-5/7
so x=-5/7 or 4
Answer:
what the formula to solve this
Step-by-step explanation:
Answer:
471.3inches
Step-by-step explanation:
Given data
Diameter= 30in
Radius= D/2= 30/2= 15in
The circumference is the same as the distance covered in one revolution
C= 2πr
Hence the distance covered in 5 revolutions is
C= 2*5*πr
Substitute
C=10*3.142*15
C= 471.3inches
Commutative property of multiplication
(32 + 18 + 13) / 3 = b
/ is divided by
you would add the boxes together and then divide them equally into the 3 displays
