Answer:
9x² + y² + 64 - 6xy - 16y - 48x
= 9x² - 6xy - 48x + y² - 16y + 64
= 9x² - 6x(y - 8) + y² - 2.8y + 8²
= (3x)² - 6x(y - 8) + (y - 8)²
= [3x - (y - 8)]²
= (3x - y + 8)²

A cuboid consists of 6 sides, 2 sides will be 9*6, 2 more will be 6*4, 2 more will be 6*9
So because there is 2 sides you will multiply the side by 2 so there is another side:
(6*9) * 2 = 108
(4*6) * 2 = 48
(4*9) * 2 = 72
108 + 48 + 72 = 228

• If b² - 4ac = 0 the 2 real and equal zeros
• If b² - 4ac < 0 then zeros are not real
The graph crosses the x- axis at 2 distinct zeros, then
b² - 4ac > 0 , that is positive → C

if the point x,y is on the y-axis which of the following is true x=0 y=0
Hi there!
Answer:
x=0
How it works:
In coordinate planes, x always goes first. Then the y comes next. If x is 0, and y is also zero, none of those would be in the y axis place...
If the x is in 0 and the y is 1,2,3,4,5.... then the y axis would be in the y axis and x would just stay the same...
If the x is 1, then the y would be 0 which means that there would be nothing in the y axis.
Therefore, the answer is x=0..

Step-by-step explanation:
the breadth of a rectangular handkerchief is 10 cm shorter than its length .if the perimeter of the handkerchief is 100cm. find its length and breadth..
plz help me
Step-by-step explanation:
Perimeter = 2(l+b)
2(x+x-10)=100cm
(x+x-10)= 100 divided by 2
(x+x-10)=50
2x-10=50
2x=50+10,60
x=60 divided by 2
X =30
Length = 30cm
Breadth= 30-10= 20cm
PLEASE MARK MY ANSWER AS THE BRAINILIEST!
Answer:
solution given:
length[l]=xcm(let)
breadth [b]=(x-10)cm
perimeter of rectangle [P]=100cm
we have
P=2[l+b]
100cm=2[x+x-10]
2x-10=[tex] \frac{100}{2} [/tex]
2x=50+10
x=[tex] \frac{60}{2} [/tex]
:.x=30cm
So
length[l]=x=30cm
breadth [b]=(x-10)=30-10=20cm

Find the y intercept of the following line (-2,1) and (1, 2.5)
Answer:
2
Step-by-step explanation:
(-2 , 1) ; (1, 2.5)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]\frac{2.5-1}{1-[-2]}\\\\= \frac{1.5}{1+2}\\\\=\frac{1.5}{3}\\\\= 0.5[/tex]
m =0.5
y -y1 =m(x -x1)
y - 1 = 0.5(x - [-2])
y - 1 = 0.5(x + 2)
y -1 = 0.5x + 0.5*2
y - 1 =0.5x + 1
y = 0.5x + 1 + 1
y = 0.5x + 2
y-intercept = 2

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total amount of money in Mary's account be = $ 120
The amount of money that gets deducted for each week = $ 5
Total number of weeks elapsed = 15 weeks
So , the equation will be
Total amount deducted after 15 weeks = number of weeks elapsed x amount of money that gets deducted for each week
Total amount deducted after 15 weeks = 15 x 5
= $ 75
Therefore , the equation will be
The amount left in Mary's account = total amount of money in Mary's account - Total amount deducted after 15 weeks
The amount left in Mary's account = 120 - 75
= $ 45
Hence , The amount of money Mary has left in her account is $ 45

A tea shop brewed 8 7/8 pitchers of chamomile tea, of which it sold 2 3/5 pitchers. How many pitchers remained unsold?
Answer:6 11/40
Step-by-step explanation: You can change your units to decimals or to fractions of equal value. Decimals are easier for this so 8 7/8= 8.875 and 2 3/5 =2.6. Then subtract: 8.875-2.6= 6.275 You can now convert back to a fraction by simplifying the .275 into 11 by dividing by 25 and 1000 into 40 by dividing by 25. 6+11/40= 6 11/40 tea left
Answer:
6 11/40
Step-by-step explanation:
First you have to convert the fractions into improper fractions, where 8 7/8 would turn into 71/8 and 2 3/5 would turn into 13/5. Then you have to find a common denominator which would be 40, so you get 355/40 and 104/40. Then to find the remaining amount, you have to subtract 104/40 from the 355/40, so 355/40 - 104/40, which equals 251/40. This turns into 6 11/40, which can't be simplified any further. Hope this helps :)
