Answer:
x=4, x= -1
Step-by-step explanation:
Write your problem:
[tex]x^{2}[/tex] - 4 = 3x
Subtract 3x from both sides:
[tex]x^{2}[/tex] - 4 - 3x = 3x - 3x
Simplify:

the width of a rectangle is half of the length of the rectangle. if the perimeter is 84 inches what is the length of the rectangle?
Answer:
The length of the rectangle is 28 inches.
Step-by-step explanation:
We have that the width (W) of a rectangle is half of the length (L) of the rectangle:
[tex] W = \frac{1}{2}L [/tex] (1)
Also, the perimeter is 84 inches:
[tex] P = 2W + 2L = 84 in [/tex] (2)
By entering equation (1) into equation (2) we have:
[tex]2(\frac{1}{2}L) + 2L = 84 in[/tex]
[tex] L = \frac{84}{3} = 28 in [/tex]
Therefore, the length of the rectangle is 28 inches.
I hope it helps you!

The Grow Station: 9, 11, 6, 12, 7
which statement are true regarding the measurements of center in variability of these data sets/3 choices
Answer:
The mean of tree heights at Yard Works is 8 feet. The mean of tree heights at The Grow Station is 9 feet. The mean absolute deviations of the tree heights at both yards is 2.
Answer:
The heights, in feet, of the trees for sale at two nurseries are shown below.
Yard Works: 7, 9, 7, 12, 5
The Grow Station: 9, 11, 6, 12, 7
Which statements are true regarding the measures of center and variability of these data sets? Select three choices.
________________________________________________________
1 The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
2 The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.
3 The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
4 The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.
5 The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.
Step-by-step explanation:
Yard works has...
mean=8
median=7
mode=7
range=11
because in order it is 5 7 7 9 12
(5+7+7+9+12)/5=8
5 7( 7 )9 12 is the median
and seven occurs the most
and with this logic...
THE GROWSTATION has a
mean=9
median=9
mode=n/a
range=6
_______________________________________
YEA) The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
YEA) The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.
YEA) The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.
The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.

Answer:
13cm
Step-by-step explanation:
The pythagorean theorem states that, for right triangles, [tex]a^{2} +b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.
a = 12cm
b = 5cm
c = hypotenuse
[tex]12^{2} +5^{2} =c^{2}[/tex]
[tex]144+25=c^{2}[/tex]
[tex]\sqrt{169} =c[/tex]
13 = c
Answer:
13
Step-by-step explanation:
a^2+b^2=c^2
12^2+5^2=c^2
144+25=c^2
169
square root of 169=13
13=c

What is the solution to the inequality -3x - 42 > 3?
A. X > -13
B. x < -13
C. X > -15
D. X< -15
Answer:
D. x<-15
Step-by-step explanation:
-3x-42>3 Add 42 to both sides.
+42 +42
-3x>45 Divide both sides by -3.
/-3 /-3
x>-15 Each time you multiply or divide by a negative, you flip the sign.
x<-15

What is the answer to number 10?
Answer:
979.68
Rounded up, is 980
Step-by-step explanation:
Order from least to greatest.
68%, 0.687, 20
Answer:
20, 68%, 0.687
Step-by-step explanation:
If 20 were to be a percentage, then it'll be less than 68% and 0.687. Since the 7 in 0.687 is greater than 5, you would round up when the question says so. 0.687 is greater than 68%; if you move the decimal 2 times to the right, then 0.687 would be 68.7%. Therefore the order from least to greatest is 20, 68%, 0.687.
Which of these expressions are equivalent to 4x+2(2x−5)−(3−5x) ? Choose the TWO correct answers.
a- 3x−13
b- 13x−13
c- 8x−5−3−5x
d- 8x−10−3−5x
e- 8x−10−3+5x
Answer:
4x+2(2x−5)−(3−5x) = 8x-10-3+5x
Step-by-step explanation:
We need to find the equivalent expression to 4x+2(2x−5)−(3−5x).
Using distributive property as follows :
a(b+c) = ab+ac
4x+2(2x−5)−(3−5x) = 4x+4x-10-3+5x
= 8x-10-3+5x
Option (e)
Hence, the correct option is (e) "8x-10-3+5x"

What is the relationship between sin x and cos y?
Answer:
It's graph is symmetric to the origin. Cos (x) on the other hand is an even function cos (-x) = cos (x), and its graph is symmetric to the y-axis. Notice also that the graphs are exactly the same shape but horizontally shifted /2 units. They are related by: sin (x) = cos (x - /2) and cos (x) = sin (x + /2).

If the measure of ZDEF is 65°, what is the measure of DE?
A. 115°
65
B. 65°
C. 130°
D. 32.5°
Answer:
I believe it is C because i heard of that one before
The measure of DE is 130 degrees if the measure of DEF is 65 in the circle option (A) is correct.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Circle is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have:
The measure of DEF = 65 degrees
C is the center.
Angle CED = 90 - 65 = 25 degrees
Angle DCE = 180 - 25 - 25
Measure of DE = 130 degrees
Thus, the measure of DE is 130 degrees if the measure of DEF is 65 option (A) is correct.
