Answer:
v^2 - 4v - 32
Step-by-step explanation:
Expand (v - 8) (v + 4) using the FOIL method.
apply the distributive property.
v (v + 4) - 8 (v + 4)
v x v + v x 4 - 8 (v + 4)
v x v + v x 4 - 8v - 8 x 4
simplify and combine like terms.
v^2 + v x 4 - 8v - 8 x 4
v^2 + 4 x v - 8v - 8 x 4
v^2 + 4v - 8v - 32
v^2 - 4v - 32
3. 5 bananas cost $2. At this rate, how much do 4 bananas cost?
Answer:
$1.60
Step-by-step explanation:
Write out a proportion.
5 bananas/$2 = 4 bananas/$x
Simplify the proportion, by cross multiplying.
2 times 4 equals 8, then divide 8 by 5, which will give you our variable x.
8/5 is the same as 1.60, so the cost of 4 bananas will cost $1.60.

Evaluate 1 1/4 x 6 giving your answer as a mixed number in simplest form.
Answer:
7 1/2
Step-by-step explanation:
First remember the rule to multiply fractions, you gots to have fractions; so convert 1 1/4 into a mixed number. To do this, multiply 1 by 4, then add 1. It equals 5/4.
Next multiply 5/4 by 6. You can "cross simplify" to make this problem easier and you will the the simplest form. To cross simplify, divide 6 and 4 by 2. The new thing is 5/2 times 3. This equals 15/2.
Divide but don't turn into decimal. 7 remainder 1 the divisor is 2.

A skating rink charges $4 for ice skate rental and a
fee of $3 for each hour of skating. Kelsey paid a total
of $10 to rent skates and to skate for n hours. What
is the value of n ?
What is the value of n
Answer:
N=2 hours
Step-by-step explanation:
She spent a total of 10 dollars.
Ice skate rental costs 4$
The fee per hour for skating is 3$ per hour
So minus 10$ by 4$, which is 6$
So now here at six and each fee per hour cost 3$, so therefore she skated for N= 2 hours.

James went on a fishing trip. The ratio of the number of times he cast his fishing pole, P, to the number of times he caught a fish, F, was 8 : 1. Based on this data, select all true statements.The equation P=18F can be used to calculate the number of times James cast his fishing pole given the number of fish he caught.
If James caught 32 fish, then he cast his fishing pole 4 times.
If James cast his fishing pole 64 times, then he caught 8 fish.
The equation F=18P can be used to calculate the number of fish James caught given the number of times he cast his fishing pole.
The equation F=8P can be used to calculate the number of fish James caught given the number of times he cast his fishing pole.
Answer:
I need help with this question too do you know the answer
Step-by-step explanation:
Answer:
the answer is If James cast his fishing pole 64 times then he caught 8 fish. The equation F=1/8P can be used to calculate the number of fish James caught given the number of times he cast his fishing pole.
Step-by-step explanation:
64 divided by 8 is 8 or you can create a chart showing 8,1624,32,40,48.56,64 and on the other side showing 1,2,3,4,5,6,7,8 those are factors.and then since the equation is that p is the number of times he cast his fishing pole and F is the number of times he caught a fish you can say F=1/8P or F= 1 divided by 8P
