Answer:
The expression "20a/4" can be simplified by dividing 20a by 4.
To do this, we can first simplify 20/4, which is equal to 5. Then we can multiply 5 by a to get the final answer:
20a/4 = (20/4) * a = 5 * a = 5a
Therefore, the expression "20a/4" simplifies to "5a".
Step-by-step explanation:
20a/4 is a mathematical expression that involves division. To find the value of this expression, we need to divide the value of 20a by 4.
We can simplify the expression by dividing the numerator (20a) by the denominator (4). When we divide 20a by 4, we get:
20a/4 = 5a
Therefore, 20a/4 is equivalent to 5a.
To summarize, the expression 20a/4 means dividing 20 times the value of variable "a" by 4. The result of this expression is equivalent to 5 times the value of variable "a".

simplify (a+b) (a+2ab) + (2a-b) (a-b)
Step-by-step explanation:
since im typing it out its neater to seperately do left side expression and right side expression
(a+b)(a+2ab) = a(a+2ab) + b(a+2ab) (expansion of terms)
=a^2 +2a^2b + ab + 2ab^2 (remember order of algebraic terms doesnt matter so for instance ab=ba)
other side
(2a-b)(a-b) = 2a(a-b) -b(a-b)
=2a^2 -2ab -ab +b^2 (remember -b x -b = b^2, negatives cancel out when they multiply by each other)
if you want to present this on paper, you would have done the both expansions in one line, to reach this line
.
.
.
= a^2 + 2a^2b + ab + 2ab^2 + 2a^2 -2ab -ab +b^2
=3a^2 + b^2 -2ab + 2a^2b + 2ab^2

Answer:
Step-by-step explanation:
a. The blue curve represents the puppies weight because the graph only shows 2 years, humans aren't done growing until they are 14-20. You can see the pink line is still going up, which makes sense for a human. Dogs reach close to adult size after 1 year, and may grow a little more after, but it remains steady.
b. If the graph is to scale, then it appears this puppy has almost finished growing just after one year. It grew the fastest in the first 6 months, and then a little more the next 6, and it looks like it was finished growing after a little over a year.
The baby was a little slower to start, it looks like there was less growth the first 6 months, then the growth took off and the baby is continuing to grow quickly going off the chart before the 2 year mark.
At about 3 months it looks like the baby and puppy weigh the same, but the puppy continues to grow a little faster, at 8 months it looks like they weigh the same again, but the baby takes off in weight and the puppy only gains a little more.

Lei had php 150. She spend php 48 for spaghetti and Php 12. For the drinks what percent of her money was left
Answer:
She has 60% of money left.
Step-by-step explanation:
You have to find out how much Php that Lei has left :
Php 150 - Php 48 - Php 12 = Php 90
She has a remaining of Php 90. Next, you have to find the percentage by dividing hy original amount and then, multiply by 100 :
(90/150)×100 = (3/5)×100 = 60%

A local cable tv company charges a base fee of $35 per month plus an additional
$12 per month for each additional premium channel. The monthly charges can be
represented with equation C = 35 + 12p, where p is the number of premium channels
and C is the total monthly charge.
A. What would be the monthly charge for the service if you are watching 5
premium channels? Show how you found your answer.
Answer:
95$
Step-by-step explanation:
Since there are 5 premium channels, we multiply the rate of charges by the number of premium channels to get the extra payment.
5 channels x 12$ per channel = 50$
Now we add this to 35 since C= 35 + 12 or 35 plus the premium channel costs
35$ + 50 = 95$

Step-by-step explanation:
Step 1: Define
f(x) = x - 14
g(x) = x² + 2x + 12
Step 2: Find g(f(x))
g(f(x)) = (x - 14)² + 2(x - 14) + 12
g(f(x)) = x² - 28x + 196 + 2x - 28 + 12
g(f(x)) = x² - 26x + 180
Step 3: Find g(f(9))
g(f(9)) = 9² - 26(9) + 180
g(f(9)) = 81 - 234 + 180
g(f(9)) = -153 + 180
g(f(9)) = 27

Determine the function's value when x = -1.
O g(-1) = -3
Og(-1) = 0
O g(-1) = 1
Og(-1) = 27
Answer:It is option c. Because when we substitute x for -1 we get the remainder as 1.
The value of function's when x = -1 is,

What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;'
The function is,
⇒ g (x) = x³ + 6x² + 12x + 8
Now, Substitute x = - 1 in above function, we get;
⇒ g (x) = x³ + 6x² + 12x + 8
⇒ g (-1) = (-1)³ + 6 (-1)² + 12 (-1) + 8
⇒ g (-1) = - 1 + 6 - 12 + 8
⇒ g (-1) = 1
Thus, The value of function's when x = -1 is,
⇒ g (- 1) = 1

Suppose there are 20 people in a room and the mean amount of cash held by these 20 people is $14.50 per person. If two people enter the room carrying $4.00 and $5.00 respectively, what does the mean amount of cash in the room become? Give your answer in dollars and cents; that is, precise to two decimal places.
Answer:
13.59
Step-by-step explanation:
The calculation of amount of cash in the room is shown below:-
[tex]\$14.50 = \frac{\Sigma xi}{20}[/tex]
= 20 × $14.50
= $290
Now, the new sum is
= ∑xi + $4.00 + $5.00
= $290 + $4.00 + $5.00
= $299
Total person in the room is
= 20 + 2
= 22
So,
Mean amount of cash in the room = New sum ÷ Total person in the room
= $299 ÷ 22
= 13.59

Consider the function, f (x) = 2x – 1
Use the above function to complete the following table.
Answer:
x f(x)
1 1
0 -1
-1 -3
2 3
Step-by-step explanation:
∵ The given function is f(x) = 2x - 1
∵ The table has the values of x
→ Substitute the values of x in the function to find the values of f(x)
∵ x = 1
→ Replace every x in the function by 1
∴ f(1) = 2(1) - 1
∴ f(1) = 2 - 1
∴ f(1) = 1
∵ x = 0
→ Replace every x in the function by 0
∴ f(0) = 2(0) - 1
∴ f(0) = 0 - 1
∴ f(0) = -1
∵ x = -1
→ Replace every x in the function by -1
∴ f(-1) = 2(-1) - 1
∴ f(-1) = -2 - 1
∴ f(-1) = -3
∵ x = 2
→ Replace every x in the function by 1
∴ f(2) = 2(2) - 1
∴ f(2) = 4 - 1
∴ f(2) = 3

Cases:
1. x = 1
f(1) = 2 - 1 = 1
2. x = 0
f(0) = 0 - 1 = -1
3. x = -1
f(-1) = -2 - 1 = -3
