(3x-2) * (x) = 65
3x^2 - 2x - 65 = 0
Δ/4 = 1 + 195 = 196
x1 = (1 + 14)/3 = 5
x2 (1-14)/3 = -13/3 (not acceptable because a length can’t be negative)

Francis plants an orchard of peach trees. He plants 56 trees in 8 equal rows. What equation represents this situation if x is the number of trees in each row?
Answer: 8x = 56
Step-by-step explanation:
Since the information given is that Francis plants an orchard of peach trees and that he plants 56 trees in 8 equal rows, the equation that represents this situation if x is the number of trees in each row will be:
(8 × x) = 56
8x = 56
Therefore, to know the number of trees in each row, we've to find the value of x. This will be:
8x = 56
x = 56/8
x = 7
Therefore, the number of trees in each row is 7.

Find X.
Round to the nearest tenth.
Z
20 ft
22ft
X
18 ft
Y
X= [?]°
Answer:
X≈ 70.5°
Step-by-step explanation:
Using the cosine rule in Δ XYZ
cos X = [tex]\frac{y^2+z^2-x^2}{2yz}[/tex]
with x = 22, y = 20, z = 18 , then
cos X = [tex]\frac{202+18^2-22^2}{2(20)(18)}[/tex]
= [tex]\frac{400+324-484}{720}[/tex]
= [tex]\frac{240}{720}[/tex] , then
∠ X = [tex]cos^{-1}[/tex] ([tex]\frac{240}{720}[/tex] ) ≈ 70.5° ( to the nearest tenth )

4/5x - 1/3x = x - 1 what is the value of x?
Answer:
x = 15/8 or 1 7/8
Step-by-step explanation:
eliminate denominators by multiplying everything by 15 to get:
15(4/5x) - 15(1/3x) = 15(x) - 15(1)
12x - 5x = 15x - 15
7x = 15x - 15
subtract 15x from each side to get:
-8x = -15
divide each side by -8 to get:
x = 15/8 or 1 7/8
Please help me with this homework
Answer:
6 √15
Step-by-step explanation:
a^2 + b^2 = c^2
plug in your values
(6*6) + (b^2) = (24*24)
solve your exponents
36 + b^2 = 576
subtract 36 from both sides
b^2 = 540
find the square root of both sides
√b^2 = b
√540 = 6√15
b= 6√15
Which graph represents the solution of x2 + 9y2 <81 and y2 + 2
Answer:
C on edge
Step-by-step explanation:
the guy above is correct
The graph that represents the given inequalities is required.
The required graph is attached.
The inequalities are
[tex]x^2+9y^2<81[/tex]
[tex]y^2+2<x[/tex]
Converting to general forms
Ellipse
[tex]\dfrac{x^2}{9^2}+\dfrac{9y^2}{9^2}<1\\\Rightarrow \dfrac{x^2}{9^2}+\dfrac{y^2}{3^2}<1[/tex]
So,
[tex]a=\pm9[/tex]
[tex]b=\pm3[/tex]
The vertices of the major axes are [tex](9,0)[/tex] and [tex](-9,0)[/tex]
The vertices of minor axes are [tex](0,3)[/tex] and [tex](0,-3)[/tex]
The center lies on the origin.
Since, the sign of the inequality is [tex]<[/tex] the shaded region will be inside the ellipse excluding the ellipse.
Parabola
[tex]x>1(y-0)^2+2[/tex]
So,
Vertex of parabola = [tex](2,0)[/tex]
Since, the square term is [tex]y^2[/tex] the axis of symmetry is the [tex]x[/tex] axis.
The parabola will open towards the positive x axis.
The shaded region is the area in the parabola excluding the parabola due to the [tex]>[/tex] sign.

Help pleaseeeeeeeeee
9514 1404 393
Answer:
47 -6√10
Step-by-step explanation:
As you know, the area of a square is the square of the side length. It can be helpful here to make use of the form for the square of a binomial.
(a -b)² = a² - 2ab + b²
(√2 -3√5)² = (√2)² - 2(√2)(3√5) + (3√5)²
= 2 - 6√10 + 3²(5)
= 47 -6√10
__
Check
√2-3√5 ≈ -5.29399 . . . . . . . . note that a negative value for side length makes no sense, so this isn't about geometry, it's about binomials and radicals
(√2-3√5)² ≈ 28.02633
47 -6√10 ≈ 28.02633
A zip line starts on a platform that is 40 meters above the ground. The anchor for the zip line is 198 horizontal meters from the base of the platform. How long is the zip line? *
Answer:
Solution given:
perpendicular distance =height [p]=40m
base or horizontal distance [b]=198m
Hypotenuse or zip line [h]=?
Now
By using Pythagoras law
h²=p²+b²
h²=40²+198²
h=√40804
h=202m
So the Zip line is 202m long.

Answer:
3, 20, 2, and 2.5
Step-by-step explanation:
For each question, they gave you an x and y value. If you substitute them into the equation and then solve for k, you get your answer.
On the first one, x is 12 and y is 1/4. If you put those into the equation they gave you y = k/x, you get 1/4 = k/12
3/12 is 1/4 so the first k is 3.
Second one y = k/x. x is 4 and is 5. So 5 = k/4
20/4 is 5, so the second k is 20.
