Answer:
[tex]\dfrac{(a+b)}{ab}[/tex]
Step-by-step explanation:
The given expression is :
[tex]\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}[/tex]
It can be solved as follows :
[tex]\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}=\dfrac{a}{b(a-b)}+\dfrac{b}{a(b-a)}\\\\=\dfrac{a}{b(a-b)}+\dfrac{b}{-a(-b+a)}\\\\=\dfrac{1}{a-b}(\dfrac{a}{b}-\dfrac{b}{a})\\\\=\dfrac{a^2-b^2}{ab(a-b)}\\\\=\dfrac{(a-b)(a+b)}{ab(a-b)}\\\\=\dfrac{(a+b)}{ab}[/tex]
So, the solution of the given expression is equal to [tex]\dfrac{(a+b)}{ab}[/tex].

Figure D'EFG' is a dilation with center (0,0) of figure DEFG. What is the scale factor? Enter your answer in the box.
ILL GIVE BRAINLIST BUT PPLEASE HELP
Step-by-step explanation:
To work out the scale factor, divide one of the sides from the larger shape from the smaller shape so:
15/6 = 2.5
So your scale factor would be 2.5
And to check this, multiply 2.5 by 6 and u should get 15, so you know it is correct! :)

Factorise x^2+11x+18
Answer:
(x + 9)(x + 2 )
Step-by-step explanation:
Sum =11
Product = 18
Factors = 9 , 2
When you multiply (9*2 = 18) and when you add (9 +2 = 11).
x² + 11x + 18 = x² + 9x + 2x + (9*2)
=x(x + 9) + 2(x + 9)
= (x + 9)(x + 2 )
Answer:
(x+9) (x+2)
Step-by-step explanation:
x^2+11x+18
x^2+9x+2x+18
x(x+9)+2(x+9)
(x+9) (x+2)

Matrix A has 2 rows and 3 columns whereas matrix B has3 rows and 2 column
Can AB be multiplied? Can BA be multiplied? Give the reason
Step-by-step explanation:
for any matrix multiplication number of columns of first matrix should be equal to number of rows of second matrix.
For AB
A has 3 columns and B has 3 rows so it matches . Hence can be multiplied.
For BA
B has 2 columns and A has 2 rows it also matches so can be multiplied

Rule what u do to the bottom u have to do to the top
now that u multiply 50 down to make 100 u have to do as the rule say what u need to do is also multiply 1 to 50 to get the answer
as u might know that 100 mean % so u pet the top number and then %

Ms Singh wants to buy a new television that costs £840
Each week, Ms Singh receives a wage of £300
She saves 40% of her wage each week.
Calculate how many weeks it will take Ms Singh to save enough money to
buy the television.
weeks
Some student
Cost of a television Ms. Singh wants to buy = £840
Ms. Singh's weekly wage = £300
Money she saves each week :
= 40% of her weekly wage
[tex] =\tt 40\% \: of \: 300[/tex]
[tex] = \tt \frac{40}{100} \times 300 [/tex]
[tex] =\tt \frac{40 \times 300}{100} [/tex]
[tex] =\tt \frac{12000}{100} [/tex]
[tex]\color{plum} = \tt£120[/tex]
Thus, Ms. Singh's weekly savings = £120
Number of weeks in which she will be able to buy a TV :
[tex] = \tt \frac{840}{120} [/tex]
[tex]\color{plum} =\tt 7 \: weeks[/tex]
Therefore, Ms. Singh will be able to buy a TV from her savings in 7 weeks.

Step-by-step explanation:
Hank's car travels 600 feet in 20 seconds. Andy's motorcycle travels 300 feet in 12 seconds. Which is faster, the car or the motorcycle? Explain your reasoning.
Answer:
the car travels faster
Step-by-step explanation:
Since the motorcycle has traveled 300 feet, and the car has traveled 600 feet, we will divide 600 by 2
600 divided by 2 = 300
Hank would have traveled 300 feet in 10 seconds
Andy traveled 300 feet at 12 seconds
Therefore Hanks car travels faster
Answer:
The car travels faster
Step-by-step explanation:
600 ft per 20 secs
How many feet in one sec?
600/20 = 30
Hank's car = 30 feet per second
300 feet in 12 sec
How many feet in one sec?
300/12 = 25
Andy's motorcycle = 25 feet per second

In a school, 4 out of every 7 students are girls. if there are 84 students at the school, how many are boys. AND SHOW WORKING
Answer:36
Step-by-step explanation:
[tex]\frac{4}{7} =\frac{48\\}{84}[/tex]
for every 7 students there are 4 girls, so for every 84 there must be 48
7*12=84
4*12=48
so, in all 84 students there are 48 girls
so amount of boys=84-48=36
there are 36 boys
How do you find the height of a parallelogram without the area of it?
Answer:
See: https://brainly.in/question/12682555
Step-by-step explanation:
The link provided will take you to a differently worded explanation from another user.
You may see the "slant" referred to as a "hypoteneuse", as the shape created by the line of height(or altitude) is a right triangle. Given the base of the triangle and the "slant" or "hypoteneuse", format the equation (a²+b²=c²)-where a represents the height(altitude), b represents the base, and c represents the slant(hypoteneuse)- to fit your needs:
c²-b²=a². From this point, find the square root(√) of a. If it cannot be simplified further, then (√a) is your solution.
2. Classify the angle as acute, obtuse, right or straight.
O acute
O obtuse
Oright
straight
HELP ASAP
Answer:
Please include the details of the angle
Step-by-step explanation:
When the angle is 93 degrees, the the angle is a obtuse angle. option B is correct.
Given that the measure of angle A is 93 degrees, we can classify the angle as follows:
Angle A = 93 degrees
We know that if angle is less than 90 degrees, it is acute.
if angle is greater than 90 degrees, it is obtuse.
if angle is equal to 90 degrees, it is right angle.
Since the angle measures greater than 90 degrees, it falls within the range of an obtuse angle.
Therefore, the correct classification for angle A is obtuse.
