Answer:
n^2+2n+1
Step-by-step explanation:
-2-8-18-32-50
difference=-6-10-14-18
common differences=-4-4-4-4-4
-2-8-18-32-50
n^2=1,4,9,16,25
minus it
=-1,-4,-9,-16,-25
differences 2,5,7,9
common differences=2
2,4,6,8
so 2n+1
so the answer is n^2+2n+1

Answers
Answer:
b = 12
Step-by-step explanation:
hi! so this looks like a right triangle because it has a right angle which is 90 degrees! that means we can use the Pythagorean theorem to solve for the missing leg.
The Pythagorean theorem: [tex]a^{2} + b^{2} = c^{2}[/tex]
a and b will be the two shorter legs, so it does not matter which of the two legs are which! in this problem, 5 and b (the missing leg) are the two shorter legs! c is always the hypotenuse, which is the sloped-looking line. in this problem, 13 is the hypotenuse! this line is the longest side on every right triangle!Let's solve for the missing leg now!
1) first, we need to plug in the missing numbers into the equation
[tex]5^{2} + b^{2} = 13^{2}[/tex]
2) next, let's simplify the problem
[tex]25 + b^{2} = 169[/tex]
3) now, let's isolate the variable, b
[tex]b^{2} = 144[/tex]
4) finally, we have to take the square root of b so it will be b not [tex]b^{2}[/tex]
b = 12
Let's plug in our answer to the equation to check if it is correct!
[tex]5^{2} + 12^{2} = 13^{2}[/tex]
25 + 144 = 169
169 = 169 hooray!
you do not have to do all of this work if you memorize the Pythagorean triples!
(3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17) , (9, 40, 41)these are automatic matches! for example: [tex]3^{2} + 4^{2} = 5^{2} --> 9 + 16 = 25 --> 25 = 25[/tex]comment or message if you have any questions :)

Solve the inequality- 5/2(3x+4)<6-3x. Show your work.
Answers
Answer:
x < -8/21
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex](\frac{5}{2} * 3x) + (\frac{5}{2} * 4) < -3x + 6[/tex] [tex]\frac{15}{2}x + 10 < -3x + 6[/tex]Step 2: Add 3x to both sides.
[tex]\frac{15}{2}x + 10 + 3x < -3x + 6 + 3x[/tex] [tex]\frac{21}{2}x + 10 < 6[/tex]Step 3: Subtract 10 from both sides.
[tex]\frac{21}{2}x + 10 - 10 < 6 - 10[/tex] [tex]\frac{21}{2}x < -4[/tex]Step 4: Multiply both sides by 2/21.
[tex]\frac{21}{2}x * \frac{2}{21} < -4 * \frac{2}{21}[/tex] [tex]x < -\frac{8}{21}[/tex]Therefore, the answer is x < -8/21.

and the measure of angle B is 45°. What is the value of x?
Answers
Answer:
x = 15°
Step-by-step explanation:
Complementary angles are two angles whose sum = 90°
∠A + ∠B = 90°
3x + 45 = 90
3x = 45
x = 45/3
x = 15°

6x -4 = (4x-1) + 7
6x - 4 = 4x + 6
6x - 4x = 6+ 4
2x = 10
x = 10/2
x = 5
AC = 4x -1 = 4(5) - 1 = 20 - 1 = 19
I hope I helped you^_^
Answer:
19
Step-by-step explanation:
AS = AC + CS
6x - 4 = 4x -1 +7
6x - 4 = 4x + 6
Add 4 to both sides,
6x = 4x + 6 + 4
6x = 4x + 10
Subtract 4x from both sides
6x- 4x = 10
2x = 10
Divide both sides by 2
x = 10/2
x = 5
AC= 4x - 1
= 4*5 - 1
= 20 - 1
= 19

Simplify: 2k– 3k+ 3k
Answers
Step-by-step explanation:
2k - (3k - 3k) = 2k
please give me a brainliest answer
Answer:
2k
Step-by-step explanation:
Because all the values in our equation have the same variable, k, we can simply combine them.
We can begin with the first part of the equation:
2k - 3k
As you can see, we have to subtract, so 2 - 3 = -1, therefore, our answer right now is :
-1k, or -k
Now, we add on our other part of the equation:
-1k + 3k
We have to add now, so -1 + 3, which is the same as 3 - 1, equal 2. So, our most simplified form of this number sentence is:
2k

Exponential functions follow the form y = ab^x.
a is the y intercept when x is at 0. Because the last part, b^x will just be 1 since any number raised to 0 is 1.
b is the multiplier, and it’s raised to how many times it’s being multiplied.
So like you said, it’s being multiplied by 0.5. b = 0.05. And a=0.02.

Answers
Answer:
x = 7
Step-by-step explanation:
Rearrange the equation to make x the subject.
Original:
7x + 3 = 52
subtract 3 from both sides
7x = 52 -3
7x = 49
Divide both sides by 7
x = 49/7
x = 7
