Step-by-step explanation:
I guess, this expression really is
-9k² + 6k² - 7k² - 5k² + -8k² + -2k²
remember : all terms with the same base reference (either a number or a variable with the same exponent, or a function ...) can be combined.
all the terms in this expression are about k². so we can combine them all
k² × (-9 + 6 - 7 - 5 - 8 - 2) =
k² × -25 or simply -25k²
always also remember the rules of combining signs and operations :
++ = +
+- = -
-+ = -
-- = +

What are vented rotors? When are they used?
Answer:Vented Brake Rotors are common on most modern vehicles. They have a hollow channel between the inner and outer surfaces. This channel (or vent) allows the rotor to shed more heat. This helps to prevent Brake Fade

Which product is greater than 63?
7/8 x63
3/2 x 63
4/5 x 63
2/3 x 63
Answer:
The answer is 3/2 x 63
Step-by-step explanation:
3/2*63 = 189 / 2 = 94.5
7/8*63 = 441 / 8 = 55.125
2/3*63 = 126 / 3 = 42
4/5*63 = 252 / 5 = 50.4
Therefore the answer is 3/2 x 63 because it’s product is greater than 63.

Answer: [tex]3\frac{1}{3}[/tex]
Step-by-step explanation:
- t / u + vw (plug the number in)
= - 2 / (-2/3) + (-1)(-1/3)
= 2/ (2/3) + 1/3
= 2(3/2) + 1/3 (the 2 were being cancel)
= 3 + 1/3
= [tex]3\frac{1}{3}[/tex]
Answer:
A. 3 1/3Step-by-step explanation:
Given:
t = 2, u = -2/3, v = - 1, w = - 1/3Find:
- t/u + vw = - 2 / (-2/3) + (-1)(-1/3) = 3 + 1/3 = 3 1/3Correct choice is A

Answer:
Yes.
Step-by-step explanation:
They are similar by the AA (Angle-Angle) Similarity Theorem.
Angle P is congruent to Angle P,
and another angle congruency is <Q and <S OR <R and <T by the
Corresponding
Angle Congruency Theorem.
With two pairs of congruent angles, we can say that Triangle PQR and Triangle PST are similar by the AA Similarity Theorem.

The algebraic expression that represents twice the sum of some number and 3 is?
n + 2(3)
2(n + 3)
2 + n + 3
2n + 3
Answer:
2(n+3)
Step-by-step explanation:
The sum to 3 = n+3
That sum doubled (~twice) = 2(n+3)
Answer:
2(n+3)
Step-by-step explanation:
Let's look at the statement:
'twice the sum of some number and 3'
Twice means 2 multiplied by something.
What is that something? It is the sum of some number and 3.
Let's replace the some number with variable n.
So it becomes the sum of n and 3, which translates to n+3.
So you put the two parts together:
2 multiplied by (n+3), rewritten as 2(n+3).
Which of the following lines has a negative slope?
Is it Red
Is it Black
Is it Blue
Answer:
black line <3
Step-by-step explanation:
the slope is -2 :)
A negative slop occurs when the rate of change is negative. Looking at the options we have, we can pick a point from each line. The Red line will display a positive slop, the Blue line will display a positive slope, but the Black line will display a negative slope. Therefore, the Black like has a negative slope.
I hope this helps! :)
can someone help me on this one plss i REALLY need this for school
Answer:
0.9 + n = 5.2
Step-by-step explanation:
Think about it, 0.9 increased by a number is 5.2
In other words, increasing 0.9 by a number will equal 5.2
So, increasing = adding, right?
Adding 0.9 to a number will equal 5.2
0.9 + n (a number) = 5.2
find the value of x that makes this true. M<2= -9 + 7x
See picture for full problem. Please and thank you!
Step-by-step explanation:
the triangle is an Isosceles triangle
let the another two angles be 2x
and apply angle sum property of triangle here
2x + 72° = 180
2x = 180 - 72
2x = 108
x = 108/2 = 54
therefore,
angle 2 = 54°
a/q
angle 2 = -9 + 7x
now,
54° = -9 + 7x
or
-9 + 7x = 54°
7x = 54 + 9 = 63°
x = 63/7 = 9
x = 9
therefore, value of x is 9.
hope this answer helps you dear! take care
Finite geometric series:
Hi, I want to ask a question, is about... for example, take the sequence 1,2,4,8,... Notice that each number is twice the value of the previous number. So, a number in the sequence can be represented by the function f(n) = 2^n-1. One way to write the sum of the sequence through the 5th number in the sequence is E^5 n-1^2n-1. This equation can also be written as S5 = 2^0 + 2^1+2^2+2^3+2^4. If we multiply this equation by 2, the equation becomes 2(S5) = 2^1+2^2+2^3+2^4+2^5.
What happens if I subtract the two equations and solve for S5? Can I use this information to come up with a way to find any geometric series Sn in the form E^a n-1^bn-1?

His grandmother is sick, so Hassan is making a pot of bean soup to bring for dinner. The recipe calls for equal amounts of 3 kinds of beans: kidney, pinto, and black. In all, Hassan uses 2 1/4 cups of beans in the soup.
Use an equation to find the amount of each kind of bean Hassan uses in the soup.
Answer:
0.75 cup
Step-by-step explanation:
K + p + b = 2 1/4
K = p = b
Sence all beans are equal we can divide 2 1/4 by 3
2 1/4 / 3 = 3/4

Answer:
Liam's work is correct
Step-by-step explanation:
25 is a percent so should always write in fraction form
25/100
then you find what number multiply by 25 gives 150
which is 6, so you do the same on the bottom
which is 600
or 150 ÷ 25/100 which also gives 600
so 600 is the number

h(x)=2x+5 for h(x+3)
solve for h(x+3)
pls help aaaaaaaaaaaa i
Answer:
According to transitive Property of equality : If a =b and b = c then a = c
In this problem you are given with 2 equations:
h(x) = - 2x + 5 ---- 1
h(x) = 3 ------ 2
Apply transitive Property of equality to equation 1 and 2
- 2x + 5 = 3 Now solve for x.
-2x + 5 - 5 = 3 – 5 subtract 5 on both sides.
-2x = -2
(-2x)/(-2) = (-2) / (-2) Divide with -2 on both sides.
X = 1
