Divide using any method 2x^2+5x+1 ÷ X+3
Question:
Solve the equation 2x2−5x+3=0 by the method of completing square.
Answer:
We have,
2x2−5x+3=0
⇒x2−25x+23=0 (Dividing throughough by 2)
⇒x2−25x=−23 (Shifting the constant term on RHS)
⇒x2−2(45)x+(45)2=(45)2−23 (Adding (21Coeff.ofx)2 onboth sides)
⇒(x−45)2=1625−23⇒(x−45)2=16
How do you find area and perimeter of a rectangle with the side lengths of 5x^2 and 12x?
Answer:
The area can be found by multiplying the two terms, and the perimeter by doubling and adding them.
Using this, we find that the area of the rectangle is 60x³, and the perimeter is 10x² + 24x.
Step-by-step explanation:
First let's find the area:
5x² × 12x
= 60x³
Now the perimeter:
2(5x² + 12x)
= 10x² + 24x

The sides of a regular hexagon is 16ft. What is the area of the hexagon?
Answer:
665.1
Step-by-step explanation:
The formula for an area of a hexagon is [tex]\frac{3\sqrt{3}}{2}S^{2}[/tex]
the S (side) is 16 so,
[tex]\frac{3\sqrt{3}}{2}16^{2}[/tex]
=[tex]\frac{3\sqrt{3} }{2}256[/tex]
=[tex]3\sqrt{3}[/tex] × 128
= [tex]384\sqrt{3}[/tex]
round to the nearest sq. rt. means that you have to round to the nearest tenth, or 0.1
[tex]384\sqrt{3}[/tex] is 665.10751 as a decimal
665.1 as rounded. Therefore, the area of the hexagon is 665.1 sq ft

Solve the system of equations using elimination. How many solutions does the system have?
15j + 12k = 18
5j + 4k = 6
Responses
A. One solution, j = 3, k = 3
B. No solution
C. One solution, j = 10, k = 8
D. Infinitely many solutions
Answer:
I hope it helps u
Step-by-step explanation:
Let's solve your system by elimination.
15j+12k=18;5j+4k=6
Multiply the second equation by -3, then add the equations together.
(15j+12k=18)
−3(5j+4k=6)
Becomes:
15j+12k=18
−15j−12k=−18
Add these equations to eliminate j:
0=0
Answer:
Infinitely many solutions

21. Jim loves nuts. He plans to spend at most $24 to buy cashews and peanuts for after work
snacks. The Nut Shoppe sells peanuts for $3 a pound and cashews for $5 a pound. If Jim needs
to have at least 5 pounds of nuts for the week, how many of each type can he buy?
He can buy 5 of the $3 nut and 1 of the $5 nuts.
5x3=15
5x1=5
15+5=20 and that’s less than 24.
So Jim can use $20 to buy the $3 one 5 times and the $5 one 1 time.

Answer the boxes
Answer:
arithmatic sequence
common difference
5
Step-by-step explanation:
This increases by 5 each time which means that it's an arithmatic sequence
because it's arithmatic that means that we have a common difference. To find it just take the second number and subtract it by the first (5)

In rectangle FGHJ , the diagonals intersect at point M, FM = 3.2x , and JG = 40.
What is the value of x?
Enter your answer as a decimal in the box.
Answer:
[tex]x=6.25[/tex]
Step-by-step explanation:
FM=3.2x
JG=40
Generally the diagonal of a rectangle are equal to each other and diagonal bisects each other
Therefore
[tex]2FM=JG[/tex]
[tex]2*(3.2x)=40[/tex]
[tex]x=40/6.4[/tex]
[tex]x=6.25[/tex]
Answer:
x=6.25

Answer:
Angle ABF is 120°.
Step-by-step explanation:
Vertical angles are used to get the measure of angle ABG (3x) and FBE (2x) and all of those added together are 180. Then you use PEMDAS to get x. Then you find ABF by multiplying 3 by 30 (what you get when you use PEMDAS to find x) then you add 30 to that and you get 120.
The junior class sold 120 turkey dinner plates and 200 chicken dinner plates for a total of $2,150. The senior class sold 100 turkey plates and 300 chicken plates, raising $2,625. What was the cost of each turkey dinner plate? What is the cost of each chicken plate?
Answer:
Write the system of equations with 2 unknowns x and y denoting the prices of two types of chickens:
(1) 120x + 200y = 2150
(2) 100x + 300y = 2625
Solving the system of equations above we have 2 solutions:

Step-by-step explanation:
Jayce bought 5 bath towels and returned 2 hand towels. His sister Jayna bought 3 bath
towels and returned 4 hand towels. Jayce paid a total of $124 and Jayna paid a total of
5b - 2h = 124
$24. The system of equations
models this situation, where b is the
3b - 4h = 24
price of a bath towel and h is the price of a hand towel. How much does each kind of
towel cost?
Answer:
Bath towels = $32
Hand towels = $18
Step-by-step explanation:
Given:
5b - 2h = 124 (1)
3b - 4h = 24 (2)
Multiply (1) by 2 to eliminate h
10b - 4h = 228 (3)
3b - 4h = 24 (2)
Subtract (2) from (3)
10b - 3b = 248 - 24
7b = 224
b = 224 / 7
b = 32
Substitute b = 32 into (2)
3b - 4h = 24
3(32) - 4h = 24
96 - 4h = 24
-4h = 24 - 96
-4h = -72
h = -72 / -4
= 18
h = 18
Bath towels = $32
Hand towels = $18
