Answer:
C. 6Step-by-step explanation:
Given
S = n² + nS = 42, n = ?Substitute and solve for n:
42 = n² + nn² + 2*1/2n + 1/4 = 42.25(n + 0.5)² = 42.25n + 0.5 = √42.25n + 0.5 = 6.5n = 6Correct option is C

Answer:
number 2 is c
number 1 is d?
Step-by-step explanation:
because if it a has been 1 minute(m=1) the 35(1)=w --> w=35 for for one minute there is 35 words 35m=w
for 1 i cannot see, but if d says 3/4 and x=3/4 then d is the answer
Answer:
(For your second question.):
35w=m
Step-by-step explanation:
Why?
It states in the problem itself that miles types 35 words per minute.
"w" stands for words
'm' stands for minutes.
The constant rate relies on the clearest data after all. The equation itself is enough!
Remember: 1 min = 60 seconds.

The expression 3(-2m + 5) - 6(-4m - 2) can be written in the form am + b. What is the value of a + b?
Answer: 45
Step-by-step explanation:
3(-2m + 5) -6(-4m - 2) =
-6m + 15 + 24m + 12=
18m + 27
18= a 27= b 27 + 18= 45
The value of the expression a + b is 45.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
First, we can simplify the expression using the distributive property:
3(-2m + 5) - 6(-4m - 2) = -6m + 15 + 24m + 12
Combining like terms, we get:
18m + 27
So, a = 18 and b = 27, which means:
a + b = 18 + 27 = 45
Therefore,
The value of a + b is 45.

(c) Paul uses the function y = 7x + 30 to model the situation. What score does Paul’s model predict for 3 hours of homework?
(d) Describe what the number 30 in Part (c) mean in the context of the situation?
Answer:
(c) Paul's model predicts a score of 51 for 3 hours
(d) 30 represents the y intercept
Step-by-step explanation:
Given
[tex]y = 7x + 30[/tex]
Solving (c): What is y when x is 3
Substitute 3 for x in [tex]y = 7x + 30[/tex]
[tex]y = 7*3 + 30[/tex]
[tex]y = 21 + 30[/tex]
[tex]y = 51[/tex]
Solving (d): What does 30 represent
An equation is represented as:
[tex]y = mx + b[/tex]
Where
[tex]b = y\ intercept[/tex]
Compare: [tex]y = mx + b[/tex] to [tex]y = 7x + 30[/tex]
[tex]b = 30[/tex]
This implies that 30 represents the y intercept

Answer:
HL
Step-by-step explanation:
Since the ray BD bisects angle ABC, we know angle ABD and angle CBD are congruent through the definition of an angle bisector. Segment AD and segment CD are also congruent because they are equidistant from the bisector. Lastly, segment BD is congruent to segment BD through the reflexive property of equality. This gives the triangles congruency through HL theorem.
