Answer:
2x-3=2x-4
Step-by-step explanation:
2x-3=2x-4
-3=-4
Not true. Thus, no solution.
Answer:
say the equation was 2x - 5 = 2x -3
well the first thing I could do is subtract the 2x from both sides, but 2x is on both sides so there would be no x-value meaning there is no solution

Desiree wants to place a wire fence around the base of an apple tree... The tree has and mulch area around it, is shaped like a circle that has a radius of 14 inches... What length of fencing does Desiree need? ROUND TO THE NEAREST TENTH AND INCLUDE UNITS IN YOUR ANSWER
Answer:
( About ) 88 inches
Step-by-step explanation:
Considering this wire fence to be the circumference of the base of this apple tree, provided it is circular, let us solve for the amount of fencing given the radius of this circle is 14 inches;
[tex]Radius Of Circle - 14 inches,\\Diameter - 14 inches * 2 = 28 inches,\\Circumference - 2\pi r, r = radius,\\\\2\pi r - \pi d, d = diameter,\\\\Circumference Of Circle - \pi * ( 28 inches ) = ( About ) 88 inches\\Length Of Fencing = ( About ) 88 inches[/tex]
Length of Fencing rounded to 10th place, ( About ) 88 inches

11. Rocco and Biff are two koalas sitting at the
top of two eucalyptus trees, which are
located 10 m apart, as shown. Rocco's tree
is exactly half as tall as Biff's tree. From
Rocco's point of view, the angle separating
Biff and the base of his tree is 70°. How high off the ground is each koala?
Answer:
Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.
Step-by-step explanation:
Let the height of Biff's tree be represented by x, so that the height of Rocco's tree is [tex]\frac{x}{2}[/tex].
Draw a straight line from Rocco's point of view to a point t to the middle of Biff's tree. This line divides x into two equal parts, and the angle is divided into [tex]35^{0}[/tex] each.
By alternate angle property,
Tan [tex]35^{0}[/tex] = [tex]\frac{\frac{x}{2} }{10}[/tex]
[tex]\frac{x}{2}[/tex] = Tan [tex]35^{0}[/tex] × 10
= 7.00021
⇒ x = 2 × 7.0021
= 14. 0042
x = 14
Therefore, Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.
Answer:
Biff height = 9.48m
Rocco's height= 4.74m
Step-by-step explanation:
As Rocco's tree is half as tall as Biff's tree, draw a horizontal line from Rocco on Rocco's tree which intersects the Biff's tree at he middle.
The angle 70 degrees is divided by 2 because of the horizontal line.
An upper right angle triangle is form by Rocco (point A), Midpoint of Biff's tree(point B), and Biff (point C).
As
[tex]tan\theta = \frac{perpendicular}{base\\}[/tex]
where θ=35 and base= 10m
[tex]tan35=\frac{perpendical}{10}[/tex]
[tex](tan35)(10)=perpendicular\\perpendicular=4.74[/tex]
As the perpendicular found is that of a triangle formed from midpoint of Biff's, to find the total height, multiply the found perpendicular with 2.
Biff height = 4.74*2 = 9.48m
Rocco's height is half of biff height
Rocco's height= 9.48/2 = 4.74m

Sort the polynomials according to whether they are prime or non-prime.
6x3 - 5x2 + 2x-14
124 - 18x2 + 8x2 - 12
6x2 + 9x + 10x + 15
1272 - 3x + 4x +7
Answer: first, second and fourth are primes, the third is not-prime.
Step-by-step explanation:
A prime polynomial can not be reduced.
Let's see the options:
A) 6x^3 - 5x^2 + 2^x-14
You can see that we have a coefficient equal to 5 and other equal to 2.
As both are prime numbers, we can not reduce this, so this is a prime polynomial.
B) 12x^4 - 18x^2 + 8x^2 - 12 = 12x^4 -10*x^2 + 124
Both coefficients are even, so we can reduce it to:
12x4 -10*x^2 + 124 = 2*(6x^4 -5*x^2 + 72)
So this is not prime.
C) 6x^3 + 9x^2 + 10x + 15
we have that:
6 = 3*2
9 = 3*3
10 = 2*5
15 = 3*5
a polinomial is only reducible if all the coefficients share at least one prime factor, here we can see that this is not the case, so this is a prime polinomial.
D) 12x^2 -3x + 4x + 7 = 12x^2 + x + 7
Again, here we have that one coefficient is 1, the only factor of 1 is itself, so we can not reduce this polinomial, this is prime.

Step-by-step explanation:
Answer:
5 units

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 2, - 4) and (x₂, y₂ ) = (1, 0) ← 2 points on the line
d = [tex]\sqrt{(1+2)^2+(0+4)^2}[/tex]

write the equationof the line parallel to y=2x+3 and passing through the point (7,6)
Answer:
y= 2x +8
Step-by-step explanation:
y= 2x+3
gradient of given line = 2
(coefficient of x term when the coefficient of y is 1)
Parallel lines have the same gradient.
Hence gradient of the unknown line is 2.
y= 2x +c
To find the value of c, substitute a coordinate.
When x= 7, y=6,
6= 2(7) +c
6= 14 +c
c= 6-14
c= -8
Thus, the equation of the line is y= 2x +8.
What is the length of RP?
Answer:
RP = 14
Step-by-step explanation:
(whole secant) x (external part) = (whole secant) x (external part)
(x+x+2) * (x+2) = (4+6)*4
Combine like terms
(2x+2)(x+2)=10*4
2(x+1)(x+2) = 40
Divide by 2
(x+1)(x+2) = 20
FOIL
x^2+2x+x+2 = 20
x^2 +3x+2 =20
Subtract 20
x^2 +3x-18 = 0
Factor
(x +9) (x-6) = 0
Using the zero product property
x+9=0 x-6 =0
x= -9 x=6
Since the length cannot be negative
x=6
RP = x+2+x = 6+2+6 = 14

Answer: x = 117 degrees.
Step-by-step explanation: The sum of the interior angles of a pentagon should equal 540 degrees. The value of x has to make the total of the angles equal to 540. 140 + 138 + 59 +86 is 423. Now we need to subtract 423 from 540 to know the value of x since it has to all add up to 540. 540-423 is 117.
Answer:
117°
Step-by-step explanation:
sum of angles of a polygon=(n-2)*180
where n is the number of sides.
it has 5 sides.
x+86+140+138+59=(5-2)*180
x+423=3*180
x=540-423
x=117°
