Answer:
- (a + 3) / 2Step-by-step explanation:
(4a² - 36)/(24 - 8a) =4( a² - 9) /8(3 - a) =( a² - 9) /2(3 - a) =(a + 3)(a - 3)/2(3 - a) =- (a + 3) (3 - a)/2(3 - a) =- (a + 3) / 25(9 + a) < 110 what the inequality?
Answer:
Step-by-step explanation:
we will use first the distributive property and multiply
45+ 5a<110
subtract 45 from both sides
5a<110-45
5a<65 we divide by 5

Part A: Simplify the expression and write it down
Part B: Factor the simplified expression and write it down
Part C:What is the value of the expression when b=2 and c= -3
Answer:
Part A: 8b -12c -16
Part B: 4(2b - 3c -4)
Part C: 36
Step-by-step explanation:
Part A:
5b + 3c - 20 + 3b - 15c + 4
= 8b -12c -16
Part B:
Factorising 8b -12c -16
= 4(2b - 3c -4)
Part C:
= 4[2(2)-3(-3)-4)]
= 4[4+9-4]
= 4[9]

- 2x and 70 are equal, because they are vertical angles.
- 110 and 3x + 5 are equal, becasue they are vertical angles.
- so, the answer would be A.
-- this is because vertical angles are not supplementary so would not be equal to 180°

If a perfect square has a side length of x+2 and a perimeter of 44cm what is the value of x?
Answer:
The value of x is 9.
Step-by-step explanation:
Given that:
Side length of square = x+2
Perimeter of square = 44 cm
As all sides of a square are equal, therefore,
Perimeter of square = 4s
Putting all the values,
44 = 4(x+2)
44 = 4x+8
44-8 = 4x
36 = 4x
4x = 36
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{36}{4}\\x=9[/tex]
Hence,
The value of x is 9.

The cost of renting a truck is $40. An additional $0.79 is charged for each mile, m, the truck is driven. Which expression can be used to determine the total cost, in dollars, of renting a truck? (EE.2) *
Answer:
c = 40 + 0.79m
Step-by-step explanation:
The base cost is $40.
So we have:
c = 40
Then, since an additional $0.79 is charged for every mile driven, we add:
+ 0.79m
So then our equation is:
c = 40 + 0.79m
where c = total cost
and m = number of miles driven

Answer:
sin(2*36.86989765) and get .96 or 24/25
7/25
Step-by-step explanation:
Start by solving for P
sinP=3/5
take the arcsin or sin^-1 and get
p=36.86989765
Then multiply by 2 and take the sin and get
sin(2*36.86989765) and get .96 or 24/25
Then take cos(2*36.86989765)=.28 or 7/25
Answer:
Steps below
Step-by-step explanation:
sin P = 3/5
cos p = √1 - sin² P = 4/5
sin 2P = 2 * sin P * cos P = 2 * 3/5 * 4/5 = 24/25
cos 2P = cos² P - sin² P = 16/25 - 9/25 = 7/25

A jug is filled with 1 litre of orange juice. Four 200ml glasses are poured from the jug. How much orange juice is left in the jug?
Answer:
Step-by-step explanation:
As given that
Volume of jug=1 liter=1000ml
also volume of one glass=200ml
and we poured out 4 glasses so total volume of 4 glasses will be,
4 glasses volume = 4*200ml =800ml
Hence the volume of orange left in jug =1000ml-800ml =200mlStep-by-step explanation:
ml to litres = divide by 1000
200/1000 = 0.2×4= 0.8ml
Find the area of the circle. Round to the nearest tenth. Use 3.14 for π. 14 m circle
Answer:
615.44 m²
Step-by-step explanation:
3.14(14)²= 615.44 m²
Answer:
153.9 m²
Step-by-step explanation:
A = πr2 Use the formula.
A = π(7)2 Substitute. Use 7 for r.
A ≈ 3.14 × 72 Substitute. Use 3.14 for π.
A ≈ 3.14 × 49 Evaluate the power.
A ≈ 153.9 Multiply.
The area of the circle is about 153.9 m².

What is the reference angle for 192°?
A 22°
B. 68°
C. 12°
D. 78°
The required reference angle of angle 192 is 12. OPtion C is correct.
Given that,
An angle of 192°
Reference angle to be determined.
The angle can be defined as the one line inclined over another line.
Angel over angle is of 360° and angle over line is 180°
The function in mathematics to operate and diagnose the function to make the function simple or more coherent is called simplifying and the process is called simplification.
Since in the question, An angle is given of 192° its corresponding and relatable angle is to be determined.
Here, a standard measure of an angle is 180, So let the reference angle b x, for reference angle the angle must be more or less than 180. So,
x = 192 - 180
x = 12
Thus, the required reference angle of angle 192 is 12. Option C is correct.

97.94 is 83% of what number?
Answer:
97.94 is 83% of 118
Step-by-step explanation:
Let the missing number be x
97.94=83% of x
I.e, 97.94=83/100 × x
97.94=83x/100
Cross multipy 97.94/1=83x/100
We have, 97.94 × 100 = 83x × 1
9794=83x
Divide both sides by 83 to make x the subject of the formula.
9794/83=83x/83

Answer:
FC = 27
QC = 18
Step-by-step explanation:
The centroid divides the median in which it stands into a ratio of 1:2
The longer length being twice of the shorter
So in this case, what we have is that ;
FC = FQ + QC
with QC twice FQ
so QC = 2(9) = 18
while;
FC = 18 + 9 = 27
If the area of a rectangle with length (4x) is 4x2 + 12x, find the width.
Answer:
The width of a rectangle is: w = x+3
Step-by-step explanation:
Given
The length of rectangle = l = 4x
The area of rectangle = A = 4x² + 12x
To determine
The width of rectangle = w = ?
We know that the formula of the area of the rectangle is
[tex]A = wl[/tex]
substitute A = 4x² + 12x and l = 4x in the equation to determine the width w of the rectangle
4x² + 12x = w×4x
w = [4x² + 12x] / [4x]
Factor 4x² + 12x: 4x(x+3)
w = [ 4x(x+3) ] / [4x]
w = x+3
Therefore, the width of a rectangle is: w = x+3

Written as a simplified polynomial in standard form, what is the result when ( x + 2 ) 2 (x+2) 2 is subtracted from 7 x − 4 7x−4?
Answer:
-x²+3x-8
Step-by-step explanation:
Given polynomials are :
f(x) = (x+2)²
p(x) = 7x−4
We need to find a simplified polynomial when f(x) is subtracted from p(x) i.e.
p(x) - f(x) = 7x−4 - (x+2)²
We know that, (a+b)² = a²+b²+2ab
So,
p(x) - f(x) = 7x−4 -(x²+2²+2(x)(2))
= 7x−4 -(x²+4+4x)
= 7x−4-x²-4-4x
= -x²+3x-8
Hence, the result will be -x²+3x-8.
