Write an expression equivalent to (9m3 + 5m2 - 3y 2) - (2m3+2m2) - (3m2 - y2) using the fewest number of possible terms
Answers
Answer = (9m³ + 5m² - 3y²) - (2m³+2m²) - (3m² - y²) [expand the brackets]
= 9m³ + 5m² - 3y² - 2m³- 2m²-3m² + y² [group like terms]
= 9m³- 2m³+ 5m²- 2m²- 3m²- 3y²+ y² [simplify]

Step-by-step explanation:
The perimeter of the kite is: C. 2√53 + 10 units.
What is the Perimeter of a Kite?Perimeter = sum of all four sides that makes up the kite.
Find the length of each side of the kite:
WX = |-3 - 2| = 5 units
WZ = |-2 - 3)| = 5 units.
Using the distance formula, [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex], find the length of XY and ZY:
[tex]XY = \sqrt{(4 - 2)^2 + (-4 - 3)^2} \\\\\mathbf{XY = \sqrt{53} }[/tex]
[tex]ZY = \sqrt{(-3 - 4)^2 + (-2 -(-4))^2} \\\\\mathbf{ZY = \sqrt{53} }[/tex]
Perimeter of the Kite = √53 + √53 + 5 + 5 = 2√53 + 10 units.
Perimeter of the Kite = 2√53 + 10 units.

Then u use the sum product pattern
4(6x^2-11x+3)

Then find the common factor for both pairs

Answer:
x = 85°
y = 85°
Step-by-step explanation:
The sum of angles in a triangle are 180°
So 29 + 66 + x = 180
Solve for x:
180 = 29 + 66 + x
Subtract 29 and 66 from both sides
85 = x
x = 85°
_______________________________________
x = y because they are vertical angles, and are congruent.
Since x is 85°, y = 85° as well
-Chetan K
Answer:
X= 85
Y= 85
Step-by-step explanation:
All angles in a triangle add up to 180.
Because we are given two of the angles of this triangle, we can solve for X.
180= 29+66+X
Therefore,
X= 180-29-66
X= 85
To solve for Y:
if two angles are diagonal from each other with no other lines intersecting the angle (as seen in this example), then the two diagonal angles are equal.
In this example, X is diagonal to Y
Therefore,
X=Y
X=85
Y=85
7/8 - 4/5 what is the answer to this thing because i don't know it at all duhhhh
Answers
1.) Common factor: 45. 45 goes into and 8 and 5. If we list out all the factors of 8 and 5, 45 will be the lowest common factor.
2.) We need to multiply by a number to get 45 for each denominator. We can a one-step equation to figure out what we need to multiply 8 by and 5 by to get 45.
X=the factor of 8 that will get us 45.
8x=45
8x/8=45/8
x=5.625.
Y=factor of 5 that will get us 45.
5y=45
5y/5=45/5
y=9.
3.) We now know that we need to multiply 8 by 5.625 and 5 by 9 in order to get 45 as the denominator for both fractions.
7/8x5.625-4/5x9
7/45-4/45.
4.) Whatever is done to the denominator must be done to the numerator.
7x5.625/45-4x9/45
39.375/45-36/45
5.) We now have common denominators, so we simple subtract the numerators ONLY. We DO NOT subtract the denominators.
39.375/45-36/45=3.375/45.
Therefore, 3.375/45 is your answer.
