Factor out 5.
5(−9x^3-12x^2-4x)
Consider −9x^3-12x^2-4x. Factor out x.
x(−9x^2−12x−4)
Consider −9x^2−12x−4 Factor the expression by grouping. First, the expression needs to be rewritten as −9x^2+ax+bx−4. To find a and b, set up a system to be solved.
a+b=−12
ab=−9(−4)=36
Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. List all such integer pairs that give product 36.
−1,−36
−2,−18
−3,−12
−4,−9
−6,−6
Calculate the sum for each pair.
−1−36=−37
−2−18=−20
−3−12=−15
−4−9=−13
−6−6=−12
The solution is the pair that gives sum −12.
a=−6
b=−6
Rewrite −9x^2−12x−4 as (−9x^2−6x)+(−6x−4).
(−9x^2−6x)+(−6x−4)

if the ratio of two numbers is 2;3 and their G.C.F is 8 what is their L.C.M
Answers
Expert Answer:
Since the numbers are in the ratio 3:4 then let the numbers be 3x and 4x.
Thus the H.C.F. of the two numbers = x.
But the H.C.F is given as 4.
So, x = 4.
So, the numbers are,I
3x = 3 x 4 =12
And
4x = 4 x 4 = 16
We know,
H.C.F x L.C.M = Product of the two numbers
4 x L.C.M = 12 x 16
L.C.M = 48
Thus, the L.C.M of 12 and 16 , 48

A food pantry is making packages. Each package weighs 64 pounds.

1.Each package contains 4 boxes. Each box contains a 7-pound bag of beans and a bag of rice.
2.The bags of rice are all identical. Each package contains 4 identical bags of rice and a 7-pound bag of beans.
Please i rly need this!!!!!!!!!
Answers
Answer:
1) x = 14.25 2) 9
Step-by-step explanation:
1) 1 Package = 4 boxes
1 Box = 7 pounds of beans
Your equation should be 4x + 7 = 64...
because 64 is the total pounds that each package weigh! 4 becomes a a variable; 4x because it has the word "each" in it. Mostly likely, when you see "each" that number becomes a variable. 7 is a just an number you have to add to the equation.
Solve!
4x + 7 = 64
- 7 - 7 Subtract 7 from both sides
4x = 57
4x / 4 = 57 / 4 Divide 4 from both sides
x = 14.25

Jomaya has $15. She saves $2 every day. How many days will it take Jomaya to save $25?
Answers
Answer: 12.5
Step-by-step explanation: 2times 12.5 is 25
Answer:
5 days
Step-by-step explanation:
To find out this question, we can subtract the amount she wants to get, 25, by the amount she has, 15:
25 - 15 = 10
So, Jomaya wants to save up $10, and because she saves $2 every day, we can divide:
10 / 2 = 5
So, it will take Jomaya 5 days to save $25

During the Dallas marathon, a helicopter monitors the racers at a height of 527 feet. The pilot can see the runners that are in first and second place. The angle of elevation from the runner in first place to the helicopter is 45 degrees. The angle of elevation from the runner in second place to the helicopter is 60 degrees. What is the distance from the runner in 2nd place to the point directly below the helicopter? Round your answer to the hundredths place.
Answers
The distance from the runner in 2nd place to the point directly below the helicopter is given as follows:
304.26 feet.
What are the trigonometric ratios?The three trigonometric ratios are defined as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.The parameters for this problem are given as follows:
Distance of x adjacent to the angle of 60º.Opposite side of 527 feet, which is the height.Hence the distance is obtained applying the tangent function as follows:
tan(60º) = 527/x
x = 527 / tangent of 60 degrees
x = 304.26 feet.

m∠1 = 93.5°
Step-by-step explanation:
By theorem of intersecting chords inside a circle,
If two chords intersect inside a circle, angle formed between the chords measure half the sum of the measures of the intercepted arcs.
m∠1 = [tex]\frac{1}{2}(92+95)[/tex]
= [tex]\frac{187}{2}[/tex]
= 93.5°
Therefore, measure of angle 1 is 93.5°.

A scuba diver descends 80 feet, rises 25 feet, descends 12 feet, and then rises 52 feet where he will do a safety stop for five minutes before surfacing. At what depth did he do his safety stop?
Answers
Answer:
15 ft
Step-by-step explanation:
At 15 feet below the surface, the scuba diver did his safety stop.
What is the surface?The surface is the common region between two different mediums. Here in the question surface is the common region between seawater and above seawater.
Let us denote the values of descending by negative sign and rising by positive sign and we sum up all the values together.
∴ [ - 80 + 25 + (-12) + 52 ] feet.
= (-80 + 25 - 12 + 52) feet.
= - 15 feet.
So, at 15 feet below the surface the scuba diver dis his safety stop.
