Are you asking what 7 times 3 is? Or what is it you're asking
Answer:
3 ( x-1) (x+1) is the factored form
zeros are x=1, -1
Step-by-step explanation:
3x^2-3
Factor out a 3
3 ( x^2 -1)
What is inside the parentheses is the difference of squares
( a^2 -b^2) = ( a-b)(a+b)
3 ( x-1) (x+1)
To find the zeros, set this equal to zero
3 ( x-1) (x+1) =0
Using the zero product property
x-1 =0 x+1 =0
x=1, x=-1
Answer:
x= $19.25 + $36
y= total cost
Step-by-step explanation:
x= number of nights + admission
y= total cost
Double dip ice-cream cone = 25 + 2(75) = 175 cents = $1.75
Answer: $1.75
Step 2: commutative property of multiplication
Step 3: multiplicative inverse
Step 4: multiplicative identity
