Answer:
5x^2 + 20x = 5x(x + 4)
Step-by-step explanation:
Here, we want to factorize;
5x^2 + 20x
To do this, we start by writing the common factors
The common actor that we can see which is in the form of the gcf of both is 5x
Thus, the factorization will be;
5x^2 + 20x = 5x( x + 4)
Answer:
B, False,
Step-by-step explanation:
Answer:
9ft
Step-by-step explanation:
Use the pythagorean theorem.
15^2 = 12^2 + x^2

x = 9
Answer: 
Step-by-step explanation:
Given : A man earned x pesos in 10 days and spent y pesos during each of those days.
i.e. Total earning in 10 days = x
Earning per day =
[By unitary method] (1)
Money spent per day =y (2)
We know that
i.e. Subtract (2) from (1), we get
Hence, the expression to determine how many pesos he saved per day will be:-
Answer:
115.60
Step-by-step explanation:
for a tip 85x 0.30=25.50
tax 85x0.06=5.10
total extra money 5.10+25.50=30.60
total money payed 85+30.60=115.60
