Answer:
36b - 45 - 18b = 9 ( 18b - 45 )
Step-by-step explanation:
36b - 45 - 18b = 9 ( _b - _ )
first combine like terms:
36b - 45 - 18b
18b - 45
then just substitute the combined numbers into the brackets
9 ( _b - _ )
9 (18b - 45)
Answer:
9(2b-6)
Step-by-step explanation:
36b-45-18b=9
36b-18b-45-9=0
18b-54
9(2b-6) (Take 9 common from both)

Here is a rectangle.
Explain why the area of the large rectangle is 2a+3a+4a
Answer: Pythagorean theorem
Step-by-step explanation: cannot see the rectangle but I assume it’s the Pythagorean theorem
The sum of the area of all the rectangles will be 2a + 3a + 4a.
What is rectangular shape?A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.
Given:
The large rectangle has length a and width (2 + 3+ 4)
Area of the rectangle = L×W square units
A = a (2 + 3+ 4)
A = 2a + 3a + 4a
Therefore, the area of the large rectangle is 2a+3a+4a

Write an algebraic expression that represents
the following phrase:
The product of 8 and 12
Answer:
[tex]8*12[/tex]
Step-by-step explanation:
First, the problem asks for an expression; this means that there should be no equal sign. Also, the keyword "product" means that both the terms must be multiplied. So, [tex]8*12[/tex] is the final expression; this equals 96.

ABCD is a parallelogram. AB = 2x, AD = 4y - 6, BC = 3x. If the perimeter of ABCD is 180, find the values of x and y
Answer and Step-by-step explanation:
AB = DC = 2x
AD = BC = 4y - 6 = 3x
180 = 2x + 2x + 3x + 3x = 10x
18 = x
4y - 6 = 3(18)
4y = 54 + 6
4y = 60
y = 15
18 = x
15 = y
2(18) + (4(15) - 6) + 3(18) + 2(18) = 36 + 36 + 54 + 54 = 180

Identify the center and radius of the circle with the following equation: [tex]x^2+y^2+4x+8y+11=0[/tex]
Hey there,
Put the equation into the circle equation [ (x - h)² + (y - k)² = r² ].
x² + y² + 4x + 8y = -11
(x² + 4x) + (y² + 8y) = -11
(x + 2)² + (y + 4)² = 9
If that is confusing, you can always rewrite it to show exactly what you need in the circle equation.
(x - (-2))² + (y - (-4))² = 3²
Therefore, using the circle equation we can see that the center is at the point (-2, -4) and the radius is 3.
Best of Luck!
Answer:
[tex] \displaystyle \text{centre} :( - 2, - 4)[/tex]
[tex] \text{redius} : 3[/tex]
Step-by-step explanation:
we are given a circle equation
[tex] \rm \displaystyle {x}^{2} + {y}^{2} + 4x + 8y + 11 = 0[/tex]
we want to figure out the centre and the redious of the circle from the equation notice that the given circle equation is in general form given by
[tex] \rm \displaystyle {x}^{2} + {y}^{2} +A x +B y +C = 0[/tex]
general form of circle equation is a simplified version of standard form. the standard form of circle equation is given by:
[tex] \displaystyle (x - h {)}^{2} + (x - k {)}^{2} = {r}^{2} [/tex]
where:
(h,k) is the centrer is the rediousnotice that the there're two completed squares in the standard form therefore we can consider completing square to figure out the centre and the redious
indentifying centre and redious:
rearrange:
[tex] \rm \displaystyle ( {x}^{2} + 4x ) +( {y}^{2} + 8y) + 11 = 0[/tex]
cancel 11 from both sides:
[tex] \rm \displaystyle ( {x}^{2} + 4x ) +( {y}^{2} + 8y) = - 11[/tex]
add 4 to the both sides so that the equality don't affect:
[tex] \rm \displaystyle ( {x}^{2} + 4x + 4) +( {y}^{2} + 8y) = -11 + 4[/tex]
simplify addition:
[tex] \rm \displaystyle ( {x}^{2} + 4x + 4) +( {y}^{2} + 8y) = - 7[/tex]
once again to complete the square add 16 to both sides which yields:
[tex] \rm \displaystyle ( {x}^{2} + 4x + 4) +( {y}^{2} + 8y + 16) = 9[/tex]
complete the squares by using (a+b)²=a²+2ab+b² pattern:
[tex] \rm \displaystyle ( {x}+ 2) ^{2} +( {y} + 4) ^{2} = 9[/tex]
we can still rewrite it to figure out the redious and the centre:
[tex] \rm \displaystyle ( {x} - ( - 2)) ^{2} +( {y} -( - 4) ) ^{2} = {3}^{2} [/tex]
therefore we obtain:
centre:(h,k)=(-2,-4)redious:r=3and we are done!
