Answer:
[tex]4x^2 -4x - 48 = 0[/tex]
Step-by-step explanation:
Given
[tex]x= -3 \ or\ 4[/tex] -- roots
[tex]n= 4[/tex] --- leading coefficient
Required
Calculate the quadratic equation
[tex]x= -3 \ or\ 4[/tex]
Split to 2:
[tex]x = -3\ or\ x = 4[/tex]
Equate both to 0
[tex]x +3 = 0\ or\ x - 4= 0[/tex]
Multiply both together:
[tex](x + 3) * (x - 4) = 0 * 0[/tex]
[tex](x + 3) * (x - 4) = 0[/tex]
[tex]x^2 -4x +3x - 12 = 0[/tex]
[tex]x^2 -x - 12 = 0[/tex]
Multiply both sides by the leading coefficient, n
[tex]n * [x^2 -x - 12] = 0 * n[/tex]
[tex]4 * [x^2 -x - 12] = 0 * 4[/tex]
[tex]4 * [x^2 -x - 12] = 0[/tex]
Open brackets
[tex]4x^2 -4x - 48 = 0[/tex]

Pancake Palace puts a pint of maple syrup on each one of their 16 tables. The owner is filling the syrup bottles before the restaurant opens. If the bottles are half full, how many quarts would he need to fill the bottles?
Answer:
64 quarts of maple syrup needed
Step-by-step explanation:
There are a total of 2 quarts in a 1 pint. Therefore, since there are a total of 16 tables and each one has 1 pint, then there are a total of 16 pints in the restaurant. If we multiply this by 2 we get the total amount of quarts of maple syrup in all of the tables
16 * 2 = 32 quarts of maple syrup
Since the bottles are only half full we need to multiply this amount by 2 in order to get the total syrup needed to have all of the bottles filled completely.
32 * 2 = 64 quarts of maple syrup needed
Answer:
4 Quarts
Step-by-step explanation:
You need to find how much maple syrup the owner needs to fill the bottles. But first, you need to find how much syrup the bottles hold in all.
There are 16 bottles. Each bottle holds 1 pint of maple syrup. So, the bottles hold a total of 16 pints of syrup.
Now, find how much maple syrup the owner needs. The bottles hold a total of 16 pints of syrup. Because they are half full, divide by 2.
16÷2=8
The owner needs 8 pints of maple syrup, but the problem asks about quarts. So, find how many quarts are equal to 8 pints. There are 2 pints in a quart, so divide by 2.
8÷2=4
The owner needs 4 quarts of maple syrup to fill the bottles.

On a map, 1 inch equals 10 miles. Two cities are 8 inches apart on the map. What is the actual distance between the cities? The actual distance between the cities is miles.
Answer:
the actual distance between the cities is 80 miles
Step-by-step explanation:
The computation of the actual distance between the cities is shown below:
As we know that
1 inch = 10 miles
So for 8 inches it would required 80 miles
i.e.
= 8 × 10
= 80 miles
Hence, the actual distance between the cities is 80 miles

Find the value of X
Answer:
80Step-by-step explanation:
This quadrilateral is a kite
And the kite as its opposite angles equal
So based on this we can solve for x
[tex]100 + 100 + x + x = 360[/tex]
(360 here is the total sum of interior angke in a quadrilateral)
[tex]200 + 2x = 360 \\ 2x = 360 - 200 \\ 2x = 160 \\ x = \frac{160}{2} \\ x = 80[/tex]

Find the area inside the square and outside the circle. (Simplify your answer. Type an exact answer in terms of pi.)
9514 1404 393
Answer:
(676 -169π) ft²
Step-by-step explanation:
The area of the square is ...
A = s² = (26 ft)² = 676 ft²
The area of the circle is ...
A = πr² = π(13 ft)² = 169π ft²
Then the shaded area is ...
(676 -169π) ft²

Quadrilateral ABCD is a parallelogram with < BCA= 50 , < DCA=60, find value of
Answer:
[tex]ADC = 70[/tex]
Step-by-step explanation:
Given
[tex]BCA = 50[/tex]
[tex]DCA = 60[/tex]
See attachment for parallelogram and complete question
Required
Find ADC
From the attachment:
[tex]BCD = BCA + DCA[/tex]
[tex]BCD = 50+60[/tex]
[tex]BCD = 110[/tex]
Adjacent angles add up to 180.
So:
[tex]ADC + BCD = 180[/tex]
[tex]ADC = 180-BCD[/tex]
[tex]ADC = 180-110[/tex]
[tex]ADC = 70[/tex]

Answer:
y = 3x -6
Step-by-step explanation:
The three turning points of the terms divide the graph into 4 pieces. We can consider what functions apply in each piece.
x < -2
All terms are negated:
y = (3 -x) -(x +2) -(5 -x) = -x -4
-2 < x < 3
The first and last terms are negated:
y = (3 -x) +(x +2) +(x -5) = x
3 < x < 5
The last term is negated:
y = (x -3) +(x +2) +(x -5) = 3x -6
5 < x
No terms are negated:
y = (x -3) + (x +2) -(x -5) = x +4
_____
In the region of interest, the equation simplifies to y = 3x -6.
