Answer:
(y + 3)² - 8
Step-by-step explanation:
y² + 6y +1
Step 1: Divide the co efficient of y by 2
6 ÷2 = 3
Step2: Now find the square of 3
3² = 9
Step3: Add and subtract 9
y² + 6y + 9 - 9 + 1 = y² +6y + 9 - 8
= y² + 2*y*3 + 3² - 8
Compare y² +2 * y*3 + 3² with a² +2ab + b²
= (y + 3)² - 8

A ladder leans against the side of a house. The top of the ladder is 14 from the ground. The bottom of the ladder is 10 from the side of the house. Find the length of the ladder. If necessary, round your answer to the nearest tenth.
Answers
Answer:
17.2 to the nearest tenth.
Step-by-step explanation:

If x is the length of the ladder:
x^2 = 14^2 + 10^2
x^2 = 296
x = √296 = 17.2047
I think of a number, multiply it by 2 and add 1. My
answer is 15. What number was I thinking of?
Answers
Answer :: 7
Explanation ::
Okay, I'm going to stretch this explanation long so people can understand! Hopefully this helps :) I will also provide a shorter explanation so if people want to find out how to do it quicker without details to help you understand better, they can read the shorter explanation!
- long explanation -
Equation provided from the info :: (x * 2) + 1 = 15
We need to find out what number is the x. First of all, one way to do it is do the equation backwards. And the operators will be the opposite too, for example addition is the opposite of subtraction and multiplication is the opposite of division. Now once we flip the equation it should look like this:
(15 - 1) / 2 = x
Let's break the equation apart so it's easier to work with. Remember, the rule PEMDAS. Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. Why I put "and" between some words, is because they are the same level and you should go left to right from the equation. So the equation in parentheses is (15 - 1). So we just have to solve it! The answer is 14, which is an even number, so we don't have to fiddle with decimals. But if you want to know how to divide an odd natural number, feel free to comment on this answer! The equation should look like this:
14 / 2 = x
Now, all we have to do now is divide 14 in half! As someone who memorised their whole multiplication and division table, it's easy for me to figure it out. But if you haven't, try using addition! All you have to do is count up your numbers.
1 + 1 = 2
2 + 2 = 4
3 + 3 = 6
4 + 4 = 8
5 + 5 = 10
6 + 6 = 12
7 + 7 = 14!
So now we know 14 / 2 is 7. Sorry if this is too easy, I'm just giving attention to some who learn slowly, which is absolutely alright! So now we have our 2 answers. The equation now looks like this:
14 / 2 = 7.
Well we now know what the x is, and if you want to make sure it's the correct answer just flip the equation!
(7 * 2) - 1
7 * 2 = 14
14 - 1 = 15
Your answer is the same one provided, so the number is 7!
- short explanation -
The equation with the numbers provided is (x * 2) + 1 = 15
Let's flip the equation so it's easier! It should look like this:
(15 - 1) / 2 = x
Now all we have to do is solve it!
15 - 1 = 14
14 / 2 = 7
So our answer is 7! To check if the answer is correct, just re-do the unflipped equation!
(7 x 2) + 1 = ??
7 x 2 = 14
14 + 1 = 15
15 is the answer given in the text, so 7 is the correct answer.

Answers
Answer:
3
Step-by-step explanation:
4f-3 = 5f-6
First I would try to get the f's on one side and the other numbers on the other, to do this you woudl have to add 6 to both sides
4f -3 = 5f -6
+6 +6
Making it into: 4f + 3 = 5f
Now to get the 4f on the other side we will have to subtract it from both sides
4f +3 = 5f
-4f -4f
3= f (Remember you do not have to put the 1, making 3 your answer)

If x – 4 is a factor of x2 + 8x + k, what is the value of k?
Answers
Answer:
k ±16
Step-by-step explanation:
Evaluate x^2 + 8 x + k where x = -4:
x^2 + 8 x + k = k - 4 8 + (-4)^2
(-4)^2 = 16:
k - 4 8 + 16
8 (-4) = -32:
k + -32 + 16
Grouping like terms, k - 32 + 16 = k + (16 - 32):
k + (16 - 32)
16 - 32 = -16:
Answer: k ±16
Answer:
The answer is
k=−11
Explanation:
Let
f(x)=x^3−6x62+kx+10
If (x+2)is a factor
Then,
f(-2)=0
f(−2)= −8− 24 − 2k + 10= 0

Which explanation justifies how the area of a sector of a circle is derived?.
Answers
Step-by-step explanation:
We know the area of a circle is
[tex]\pi {r}^{2} [/tex]
That is when the cricle is 360 degrees full, so another formula is
[tex] \frac{360}{360} \pi {r}^{2} [/tex]
If we the find the area of the sector with angle x, then that formula will be
[tex] \frac{x}{360} {\pi}r^{2} [/tex]
Answer:
The area of a sector is part of an area of the entire circle. Determine the fraction of the circle that the sector represents and multiply it by the area of the circle.

Most of the problems is parallelogram some angles are the same. 2 angles add up to 180° are known as supplementary angles also known as linear pair.
#1:
<1 = 148° , <2= 32° , <3 = 148° , <1 = 32° , <5 = 148° , <6 = 32° , <7 = 32°
#2: All of them are 90° because of linear lines that add up to 180° / parallelogram.
#3: If <1 = 130°, then <8 = 148°.
Because Parallelogram <1 and <8 transversal.
#4 If <5 = 53° , then <3 = 127°
Because <5 = <4 so <5 + <3 = 180°
#5 If <7 = 71° , then <3 = 109°
Because <7 + <3 = 180°
#6 If <4 = 65° , then <6 = 115°
Because <5 = <4 so <4 + <6 = 180°

Step-by-step explanation:
present : lets assume raju is x years old so the father will be 2x
after 10 yrs raju will be x+10 yrs while the father will be 2x+10 yrs
therefore :
(x+10)+(2x+10)=80
liketerms together
x+2x+10+10=80
3x+20=80
3x=80-20
3x=60
simplify
x=20 so raju is 20 years old now and the father since he is twice the age of his son he is 40 years old
