Answer:
3x+2 and 3x-4
Step-by-step explanation:
We are given the quadratic equation 9x²-6x-8.
first, multiply 9 and -8 together (factors a*c, which equals to the sum that is b)
the result is -72
now think:
which two numbers add up to -6, but when multiplied, equal -72?
Those two numbers are -12 and 6
we can expand the polynomial:
9x²-12x+6x-8
factor by grouping:
3x(3x-4)+2(3x-4)
(3x-4)(3x+2)
so, the dimensions of the blanket are (3x-4) and (3x+2)
Hope this helps :)
a dealer made a profit of 25% by selling a car for a 1000 naira find the cost price of the car
Given:
A dealer made a profit of 25% by selling a car for a 1000 naira.
To find:
The cost price of the car.
Solution:
Let x be the cost price of the car.
A dealer made a profit of 25% by selling a car. So, the selling price of the car is
[tex]S.P.=x+\dfrac{25}{100}x[/tex]
[tex]S.P.=x+0.25x[/tex]
[tex]S.P.=1.25x[/tex]
It is given that the selling price of the car is 1000. So,
[tex]1.25x=1000[/tex]
[tex]x=\dfrac{1000}{1.25}[/tex]
[tex]x=800[/tex]
Therefore, the cost price of the car is 800.

14y = 12
5y = 12
4y = 2
Answer:
4y = 2
Step-by-step explanation:
9y + 5 = 7 + 3y + 2y
9y-2y-3y=7-5
4y=2
Answer:
4y=2 is your answer
Step-by-step explanation:
9y + 5 = 7 + 3y + 2y
9y+5=7+5y
maintaining common form in each side
9y-5y=7-5

Find the product of 6 and 4, subtract the difference between 14 and 6, then multiply by fraction 1 over 2.
i really need help i don't get it
Answer:
The correct answer is: Find half the difference of 14 and 6, multiply by 6, then add 4.
Step-by-step explanation:
By Hierarchy Rules of Operators, we must follow these steps:
(i) Subtract 6 from 14.
[tex]\frac{1}{2}\times 8\times 6 + 4[/tex]
(ii) Multiply the result in (i) by [tex]\frac{1}{2}[/tex] and 6.
[tex]24+4[/tex]
(ii) Add 4 to the result in (ii).
[tex]28[/tex]
Hence, the correct answer is: Find half the difference of 14 and 6, multiply by 6, then add 4.
Scale Factor
What scale factor was applied to the first rectangle to get the
resulting image?
Enter your answer as a decimal in the box.
Answer:
Scale factor = 2.5
Step-by-step explanation:
The scale factor that was applied = length of the resulting image ÷ length of the first rectangle
Length of resulting image = 7.5
Length for first rectangle = 3
Scale factor = 7.5/3 = 2.5

What is true about alternate exterior angles?
They sum to 180 degrees.
The are congruent.
They sum to 90 degrees.
They are non-adjacent.
They are adjacent.
9514 1404 393
Answer:
The are congruent.They are non-adjacent.Step-by-step explanation:
Where a transversal crosses parallel lines, the angles outside the parallel lines are called exterior angles. When they are on opposite sides of the transversal, they are alternate exterior angles.
Alternate exterior angles are congruent.
The share a side (the transversal, but not a vertex. So they are non-adjacent.
_____
Additional comment
In this geometry, corresponding angles are congruent. Of course, vertical angles are always congruent. Each alternate exterior angle is a vertical angle with one that is corresponding to the other alternate exterior angle.
Solve the equation x = 5/3 (pie) (r^3) for r.
Answer and Step-by-step explanation:
To solve for r, we need to get everything away from r. We can start off by moving five thirds, and pi.
[tex]x = \frac{5}{3} \pi r^{3}[/tex]
Multiply each side by [tex]\frac{3}{5}[/tex], then divide by [tex]\pi[/tex] (pi)
[tex]\frac{3x}{5\pi } = r^{3}[/tex]
Now, take the cubed root of both sides.
[tex]\sqrt[3]{\frac{3x}{5\pi } } = r[/tex]
^^ That is the answer.

Evaluate when
a =3 b= 4.5 and h = 6
Answer:
For Example: Evaluate a2b for a = –2, b = 3, c = –4, and d = 4.
Step-by-step explanation:
To find my answer, I just plug in the given values, being careful to use parentheses, particularly around the "minus" signs. Especially when I'm just starting out, drawing the parentheses first may be helpful:
a2 b
( )2 ( )
(–2)2 (3)
(4)(3)
12
Note how using parentheses helped me keep track of the "minus" sign on the value of a. This was important, because I might otherwise have squared only the 2, ending up with –4, which would have been wrong.
By the way, it turned out that we didn't need the values for the variables c and d. When you're given a big set of expressions to evaluate, you should expect that there will often be one or another of the variables that won't be included in any particular exercise in the set.
Evaluate a – cd for a = –2, b = 3, c = –4, and d = 4.
In this exercise, they've given me extra information. There is no b in the expression they want me to evaluate, so I can ignore this value in my working:
(–2) – (–4)(4)
–2 – (–16)
–2 + 16
16 – 2

correct 89.6162 to two decimal places
Answer:
89.62
Step-by-step explanation:
Look at the 3rd place of decimals - this is 6 so we add one to the second place.
i tryed my best
The decimal number rounded to 2 decimal places is 89.62
Given data:
The decimal number is represented as 89.6162
To round 89.6162 to two decimal places, we look at the third decimal place.
Non-zero digits are always significant
Zeros between non-zero digits are always significant
Since the digit in the third decimal place is 6, which is greater than or equal to 5, we round up the second decimal place.
Hence, rounding 89.6162 to two decimal places, the number is 89.62
