Answer:
6(a -2)(7a +2)
Step-by-step explanation:
Removing a common factor of 6 can make the quadratic factors easier to find.
= 6(7a^2 -12a -4)
We want to find factors of (7)(-4) that have a total of -12. It doesn't take much search to see they are (-14)(2), so the expression can be written as ...
= 6(7a^2 -14a +2a -4) = 6((7a^2 -14a) +(2a -4)) . . . . rewrite 'a' term; group pairs
= 6((7a(a -2) +2(a -2)) . . . . factor pair groups
= 6(a -2)(7a +2) . . . . . . . . finish factoring
A carpenter needs to cut 15-inch pieces of wood from a board of wood that is 11 feet in length.
What is the greatest number of 15-inch pieces the carpenter can cut from 6 of these wood boards?
Answer:
15-inch times 11 =165
Step-by-step explanation:
The greatest number of 15-inch pieces the carpenter can cut from 6 of these wood boards is 52.
Given that, cut 15-inch pieces of wood from a board of wood that is 11 feet in length.
We need to find the greatest number of 15-inch pieces the carpenter can cut from 6 of these wood boards.
How to convert inches to feet?Converting an inch length measurement to feet is as simple as dividing the number of inches by 12 because there are 12 inches in a foot.
Now, 11×6×12/15=52.8
Therefore, the greatest number of 15-inch pieces the carpenter can cut from 6 of these wood boards is 52.

Answer:

Step-by-step explanation:
y is inversely proportional to a*3. when y=10, a=2. a is directly proportional to x. when x=4, a=20. find the formula of y in terms of x
The first statement should be;
y is inversely proportional to a³.
Answer:
y = 0.64/x³
Step-by-step explanation:
y is inversely proportional to a³. This is;
y ∝ 1/a³
Thus, y = k(1/a³).
Where k is the constant of proportionality.
When y = 10, a = 2.
Thus; 10 = k(1/2³)
10 = k/8
k = 80.
Thus; y = 80(1/a³) - - -(1)
Also, a is directly proportional to x. Thus;
x ∝ a
So, x = ka
when x = 4, a = 20
Thus;
4 = 20k
k = 4/20
k = 1/5
Thus;
x = a/5
a = 5x
Put 5x for a in eq 1 to get;
y = 80(1/(5x)³)
y = (80/125) × 1/x³
y = 0.64/x³

Answer:
x-ints: (-5,0) and (-3,0)
Factors: (x+5)(x+3)
Step-by-step explanation:
First, make the equation equal 0. Then, because x² is x × x, factor it by doing a diamond, so you're seeing what times 15 equals 8, so 3 times 5. The factors would be (x+5)(x+3).
Then, to get the x-ints, put that back into the equation: (x+5)(x+3)=0.
-5 + 5=0 and -3 + 3=0, so x=-5 and -3, so the x-ints are (-5,0) and (-3,0)

An amateur drama group hire a theatre for their production. They expect to sell all 850 tickets, some at $12 and the rest at $8. The group require the ticket sales to cover their $3760 production costs and to make a profit of $4000. If they are to exactly achieve this target and their expectations regarding ticket sales are correct how many of the 850 tickets should they charge $12 for and how many should they charge $8 for?
Answer:
610 tickets for $8, and 240 tickets for $12.
Step-by-step explanation:
x + y = 850
8x + 12y = 7760
x = 850 - y
8(850-y) + 12y = 7760
6800 - 8y + 12y = 7760
4y = 960
y= 240
x + 240 = 850
x= 610
Answer:
240 = no. of $12 tickets
610 = no. of $8 tickets
Step-by-step explanation:
Let x = no. of $12 tickets
y = no. of $8 tickets
12x = income from selling x $12 tickets
8y = income from selling y $8 tickets
If they are to make a profit of 4000, then they need to have a total income from sales of $7760
So, x + y = 850 and 12x + 8y = 7760
y = 850 - x 12x + 8(850 - x) = 7760
12x + 6800 - 8x = 7760
4x + 6800 = 7760
4x = 960
x = 240 = no. of $12 tickets
y = 850 - 240
= 610 = no. of $8 tickets

Answer:
x=7
y= -2
Step-by-step explanation:
x+3y=1 ---------------- (1)
−3x−3y=−15 -------------(2)
Solve Equation (1) for x
x=1−3y
Substitute x=1−3y in equation (2)
−3(1−3y)−3y=−15
−3+9y−3y=−15
−3+6y=−15
6y=−15+3=−12
y=−12/6=−2
y=−2
Substitute y=−2 in equation (1)
x+3(−2)=1
x−6=1
x=1+6=7
x=7

Which of the following are valid names for the triangle below? Check all that
apply.
А
R
O A. AJKE
B. AEJR
O C. AKE
O D. AKEJ
ОЕ. ДЈЕ
OF AJAOE
Answer:
A and D!
A-JKE
D-KEJ
Step-by-step explanation:
JKE and KEJ line up and are in the correct position and order to form the triangle listed by themselves. The other ones will not form even the same shape!
The reason why the other ones aren't elgible: EJR, KE and JE just form a line, and JAOE forms an uneven trapezoidal shape (forgot what it was called)
So that would leave JKE and KEJ, which are the only ones that line up.
The correct options are ΔJKE and ΔKEJ.
A and D are correct.
What is a Triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices.
As per the given data:

ΔJKE:
This is correct as J, K and E are the vertices and written in the correct order.
ΔEJR:
This is incorrect as R is not a vertex.
ΔKE:
This is incorrect, 3 points must be there.
ΔKEJ:
This is correct as J, K and E are the vertices and written in the correct order.
ΔJE:
This is incorrect, 3 points must be there.
ΔJAOE:
This is incorrect, 3 points must be there.
Hence, The correct options are ΔJKE and ΔKEJ.
