Answer:
3 r 2 +9 r − 120
Step-by-step explanation:
Write the problem as a mathematical expression.
3 r ^2 + 9 r− 120
Factor 3 out of 3 r ^2 + 9 r − 120 .
Factor 3 out of 3 r ^2 .
3 ( r ^2 ) + 9 r − 120
Factor 3 out of 9 r .
3 ( r^ 2 ) + 3( 3 r ) − 120
Factor 3 out of − 120 .
3 r ^2 + 3( 3 r ) + 3 ⋅ − 40
Factor 3 out of 3 r 2 + 3 ( 3 r ) .
3 ( r^2 + 3 r )+ 3 ⋅ − 40
Factor 3 out of 3 ( r 2 + 3 r ) + 3 ⋅ − 40 .
3 ( r^ 2 + 3 r − 40 )
Factor.
Factor r^ 2 + 3 r − 40 using the AC method.
3 ( ( r − 5 ) ( r + 8 ) )
Remove unnecessary parentheses.
3 ( r − 5 ) ( r + 8 )
Hope this helps! :)

45% of the students who take part in a creative writing competition are boys. If 135 boys take part in the competition, find the total number of students who take part in the competition
Answer:
300Step-by-step explanation:
let the total number of students be x
45% of x is 135
that is
=(45/100)*x=135
0.45x=135
x= 135/0.45
x= 300students
Therefore the total number of students is 300

Simplify 1/2 (2a+4) please
Answer:
a+2
Step-by-step explanation:
The simplification of the expression 1/2 (2a+4) is a+2. The correct option is B.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The given expression is 1/2 (2a+4). The expression will be solved as below,
E = 1/2 (2a+4)
E = (2a / 2 ) + ( 4 / 2 )
E = a + 2
Therefore, the simplification of the expression 1/2 (2a+4) is a+2. The correct option is B.

Find the value of x
Answer:
4.9
Step-by-step explanation:
first step is to add up 44 and 77, to get 121
the goal is to get a value of 180 degrees, so taking the info we have gathered lets do 180-121 to give us 58
58 minus 9 is 49 and divide by ten the decimal gives us
4.9
10 times 4.9 is 50 plus 9 makes 58

Only x=3 is an extraneous root
Answer: only x=3 is a solution and only x=1 is an extraneous root
For the given expression (x/x-1) - (3/x) = 1/x-1 both x=3 and x=1 are solutions. The correct option is B.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is (x/x-1) - (3/x) = 1/x-1. Check the solution of the expression,
(x/x-1) - (3/x) = 1/x-1
( 3 / 3 - 1 ) - ( 3 / 3 ) = 1 ( 3 - 1 )
( 3 / 2 - 1 ) = 1 / 2
1 / 2 = 1/2
For x = 1 the value is the same.
Therefore, both 3 and 1 are solutions to the given formula (x/x-1) - (3/x) = 1/x-1.

The measure of angle a and the sum of angle c and b
Answer:
Part 1: 61 degrees Part 2: 90 degrees
Step-by-step explanation:
m<a = 180 - m<b - m<c - 29
m<c = 29
m<b = 90-29
m<b = 61
m<a = 180 - 61 -29 -29
m<a = 61 degrees
m<c + m<b = 29 + 61
m<c + m<b 90 degrees

Step-by-step explanation:
So you have to multiply first so
2 times 3 is 6
then 6 to the third power would be
6x6x6
6x6=36 then
36x6=216
then you would do 216-10 which is 206

the cost (in dollars) of a custom made t shirt is represented by 0.75n + 9.99, where n is the number of words in the design. write and interpret a simplified expression that represents the cost of 12 t shirts
Answer:
t=9.48n+119.88
Step-by-step explanation:
where t is the total cost of 12 t-shirts, and n is the number of words in the design
0.75n+9.99 is the equation for custom made t-shirts, and n represents the number of words in the design
t=12(0.75n+9.99)
where t is the total cost of t-shirts, and n is the number of words in the design
When simplified, this becomes t=9.48n+119.88

a local hamburger shop sold a combined total of 750 hamburgers and cheeseburgers on tuesday there were 50 more cheeseburgers sold than hamburgers how many hamburgers were sold on tuesday
Answer:
350 hamburgers
Step-by-step explanation:
x = hamburgers
y = cheeseburgers
x + y = 750
y = x + 50
Using substitution:
x + (x + 50) = 750
2x + 50 = 750
2x = 700
x = 350
y = 350 + 50 = 400
