Step-by-step explanation:
The general expansion of (a + b)² is
(a + b)² = a² + 2ab + b²
Applying this to the following expansions
(1)
(x + 2)² = x² + 2(2x) + 2² = x² + 4x + 4 ← missing term is x²
(2)
(2x - 3)² = (2x)² + 2(2x)(- 3) + 3² = 4x² - 12x +9 ← missing term is - 12x
(3)
(3x + 4)² = (3x)² + 2(3x)(4) + 4² = 9x² + 24x + 16 ← missing term is 16
(4)
(x - y)² = x² + 2(x)(- y) + y² = x² - 2xy + y² ← missing term is x²
(5)
(2x + 3y)² = (2x)² + 2(2x)(3y) + (3y)² = 4x² + 12xy + 9y² ← missing term is + 12xy
A bottle and a cork together cost Rs 8. The bottle costs R.s 6 more than the corkFind the cost of
both of them.
Answer:
Step-by-step explanation:
If the cost of cork is $1 then 6 more than that is the cost of bottle so
1 + 6 = 7
Cist of cork = 1
Cost of bottle = 7
Total = 7 + 1 = 8
Karen bought cupcakes for her sister's birthday party. 3 cupcakes had sprinkles on top. The other 27 cupcakes did not have sprinkles. What percentage of the cupcakes had sprinkles?
Answer:
10%
Step-by-step explanation:
so
3 cupcakes had sprinkles
27 didn't have sprinkles
which means that there are a total of 30 cupcakes, (because 3 + 27 is 30)
so then set up a proportion
part/whole = percent/one hundred
substitute in the given values
3 / 30= precent/100
simplify
1/10 = precent/100
you don't have to use cross products here because it is pretty obvious that 10 * 10 = 100 so then just multiply 1/10 by 10 and you get your answer
percent = 10

A plumber charges a fixed rate of $40 per job plus $10 for each hour, h, that he works at the job. Which equation models the total amount the plumber charges, y, if he works h hours?
Answer:
it says how many total so i know we are doing addition we are going to add 40+10=50 so the answer is $50 dollars he charges.
2t + 8 is greater than or equal to -4 ( t + 1 ), whats the answer to the equation?
Step-by-step explanation:
2t + 8 > - 4( t + 1)
2t + 8 > - 4t - 4
2t + 4t < - 4 +8
6t < 4
Divide both sides by 6
T < 4
6
t < 2
3
I think that is the answer

Solve for the indicated variable. 5y + 4x = 6 for x
solve for x
x=
Answer:
x = 3/2 - 5y/4
Step-by-step explanation:
5y + 4x = 6
-5y -5y
4x = 6-5y
/4 /4 /4
x = 6/4 - 5y/4
x = 3/2 - 5y/4
Move all terms that don't contain x to the right side and solve.

PLEASE HELP ASAP WILL GIVE BRAINLIEST!!) The function f(x) = 2x + 4 is shifted 3 units to the right to create g(x). What is g(x)?
I need help finding the values of x and y!!
Answer:
x= 22
y = 35
Step-by-step explanation:
The base angles of a isosceles triangle are equal
3x-11 = 2x+11
Subtract 2x from each side
3x-2x -11 = 2x-2x+11
x-11 = 11
Add 11 to each side
x-11+11 = 11+11
x = 22
The sum of all the angles in a triangle is 180
3x -11 + 2x+11 + 2y = 180
Combine like terms
5x +2y = 180
5*22 + 2y = 180
110 + 2y = 180
Subtract 110 from each side
110+2y-110 = 180-110
2y = 70
Divide by 2
2y/2 =70/2
y = 35

Three consecutive odd numbers sum to 1,245. What are the three numbers?
Answer:
413, 415, 417
Step-by-step explanation:
Answer:
414, 415, 416
Step-by-step explanation:
Consecutive numbers means they come one after another, like 1,2,3,4,5... So they all follow the formula x, x+1, x+2, x+3...x+n.
Since there are 3, we can say that x+(x+1)+(x+2)=1,245.
Simplify that to 3x+3=1,245, and then subtract 3 from both sides.
We get 3x=1,242. Divide that by 3, and you get x=414.
Add 1 and 2 to 414, and you get 414, 415, and 416.
You can add them up to check.
There are 3 points on the plane.Explain or determine whether point C is closer to point A or point B.
Point C us closer to point B because if you connected the points B would be in the middle of C going to A line.
Step-by-step explanation:
I hope I helped!
The perpendicular line from a point to a line is the shortest distance from the point to the line
With regards to the three points on the plane, point C is closer to point B
The reason point C is closer to point B is as follows:
The known parameter is;
Three points, A, B, and C, are located on a plane
Required:
To explain or determine whether point C is closer to point A or point B
Method:
Define, the relationship between the destination points A, and B
Find the shortest distance from point C, to the definition of points A, and B
Solution:
The relationship between points A, and B is that they form the line segment AB
The shortest distance from a point C to a line segment AB in Euclidean geometry is the perpendicular distance from the point C to the line segment AB
The line which best approximates the perpendicular line and therefore,
shortest distance from C to AB is the line segment CB
CB represents the shortest line and therefore distance from C to AB, that is
CB is shorter than line segment CA and which shows that it is shorter to go
from C to B, than from C to A or point C is closer to point B than point A
