3. the length of the rectangle is 3 less than twice the width. if the area is 9 square ft, the length and width of the rectangle.
4.given the figure below. find the area of the shaded part of the rectangle if the area of the big but angle is 6 times the area of the unshaded rectangle
Answer:
Step-by-step explanation:
1. Let the number be x
x^2 + 4x = 21
x^2 + 4x - 21 = 0
Solve the quadratic equation using factorization method
x^2 - 3x + 7x - 21 = 0
x(x - 3) + 7(x - 3) = 0
(x - 3)(x+7) = 0
x - 3 = 0 x + 7 = 0
x = 3 x = -7
The number is either 3 or -7
2. Same solution as number 1
3. Let
Width = x
Length = 2x - 3
Area of the rectangle = 9 square ft
Area of a rectangle = length × width
9 = (2x - 3) (x)
9 = 2x^2 - 3x
2x^2 - 3x - 9 = 0
Solve using quadratic formula
a = 2
b = -3
c = -9
x = -b +or- √b^2 - 4ac / 2a
= -(-3) +or- √(-3)^2 - 4(2)(-9) / 2(2)
= 3 +or- √ 9 - (-72) / 4
= 3 +or- √9 + 72 / 4
= 3 +or- √81 / 4
= 3 +or- 9 / 4
x = (3 + 9)/4 or (3 - 9) / 4
= 12 / 4 or -6 / 4
x = 3 or -3/2
Width can not be a negative value
So,
Width = x = 3 ft
Length = 2x - 3
= 2(3) - 3
= 6 - 3
= 3ft
2.if the sum of the square of the number and 4 time that number is 21 the what is the number?
3. the length of the rectangle is 3 less than twice the width. if the area is 9 square ft, the length and width of the rectangle.
4.given the figure below. find the area of the shaded part of the rectangle if the area of the big but angle is 6 times the area of the unshaded rectangle
Unshaded area
Length = 2x
Width = x
Shaded area
Length = (2x+3)
Width = (x+3)
Area of the shaded area = 6 × the unshaded area
(2x) (x) = 6(2x + 3)(x+3)
2x^2 = 6(2x^2 + 6x + 3x + 9)
2x^2 = 12x^2 + 36x + 9x + 54
2x^2 = 12x^2 + 45x + 54
12x^2 + 45x + 54 - 2x^2 = 0
10x^2 + 45x + 54 = 0

3x + 4.7 < -1.5x + 6.5
Answer:
x < .4
Step-by-step explanation:
Please mark Brainliest when you’re able :)
Answer:
Step-by-step explanation:
Step 1 - replace the < with an =
3x + 4.7 = -1.5x + 6.5
Step 2 - subtract 4.7 from each side, and add 1.5x to each side
3x + 1.5x = 6.5 - 4.7
4.5x = 1.8
Step 3 - divide each side by 4.5
x = 1.8/4.5
x = .4
Step 4 - change the = back to <
x < .4
Just make sure when you do it this way you check the answer because if you solved by subtracting 3x and subtracting 6.5 you would end up with .4 = x this .4 < x which is false. So depending what number you get always plug in a number bigger and smaller into the original to check. In this case 0 and 1 work.
3(0) + 4.7 < -1.5(0) + 6.5
4.7 < 6.5 which is true.
3(1)+ 4.7 < -1.5(1) + 6.5
3+4.7 < -1.5 + 6.5
7.7 < 5 which is false
So we know the direction on our < is right.

Choose 2 answers: Choose 2 answers: (Choice A) A \dfrac{4^1}{4^3} 4 3 4 1 start fraction, 4, start superscript, 1, end superscript, divided by, 4, cubed, end fraction (Choice B) B \dfrac{1}{4^{2}} 4 2 1 start fraction, 1, divided by, 4, squared, end fraction (Choice C) C 4^3\cdot 4^14 3 ⋅4 1 4, cubed, dot, 4, start superscript, 1, end superscript (Choice D) D (4^{-1})^{-3}(4 −1 ) −3
Answer:
[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{4^{1}}{4^{3}}[/tex]
[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{1}{4^{2}}[/tex]
Step-by-step explanation:
Given
[tex]\dfrac{4^{-3}}{4^{-1}}[/tex]
Required
Choose equivalent expressions
Choosing the first answer:
[tex]\dfrac{4^{-3}}{4^{-1}}[/tex]
Split expressions
[tex]4^{-3} * \frac{1}{4^{-1}}[/tex]
Apply laws of indices: [tex](a^{-b} = \frac{1}{a^b})[/tex]
[tex]\frac{1}{4^3} * \frac{1}{4^{-1}}[/tex]
Apply laws of indices: [tex](a^{-b} = \frac{1}{a^b})[/tex]
[tex]\frac{1}{4^3} * \frac{1}{1/4}[/tex]
[tex]\frac{1}{4^3} * \frac{4^1}{1}[/tex]
[tex]\frac{4^1}{4^3}[/tex]
Hence:
[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{4^{1}}{4^{3}}[/tex]
Choosing the second:
[tex]\dfrac{4^{-3}}{4^{-1}}[/tex]
Apply law of indices: [tex](\frac{a^m}{a^n} = a^{m-n})[/tex]
So,
[tex]\dfrac{4^{-3}}{4^{-1}} = 4^{-3-(-1)}[/tex]
[tex]\dfrac{4^{-3}}{4^{-1}} = 4^{-3+1)}[/tex]
[tex]\dfrac{4^{-3}}{4^{-1}} = 4^{-2}[/tex]
Apply law of indices: [tex](a^{-b} = \frac{1}{a^b})[/tex]
So:
[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{1}{4^{2}}[/tex]

What is the equation of the line that passes through the point (-4, 4) and has a slope of 3/4
Answer:
y=3/4x+7
Step-by-step explanation:
You want to find the equation for a line that passes through the point (-4,4) and has a slope of 3/4.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was 3/4. So you can right away fill in the equation for a line somewhat to read:
y=3/4x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-4,4). When x of the line is -4, y of the line must be 4.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the 3/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,4).
So, why not plug in for x the number -4 and for y the number 4? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-4,4). y=mx+b or 4=3/4 × -4+b, or solving for b: b=4-(3/4)(-4). b=7.

La siguiente funcion representa el costo del alquiler de un auto, en soles, en funcion del X de dias que se requiera = F (X) = 50 + 80 X
Answer:
Dado que f (x) = 50 + 80x, obtenemos m = 80, esto significa que el costo aumenta en 80 cada día
Step-by-step explanation:
La siguiente función representa el costo del alquiler de un auto, en soles, en función del número x de días que se requiera: f(x) = 50 + 80x. ¿Cuánto vale su pendiente y qué representa? a) 130; representa que, por cada día de alquiler, el costo se incrementa en 130 soles. b) 80; representa que, por cada día de alquiler, el costo se incrementa en 80 soles. c) 50; representa que, por cada día de alquiler, el costo se incrementa en 50 soles. d) 30; representa que, por cada día de alquiler, el costo se incrementa en 30 soles
Answer:
La función es una función lineal. Una función lineal tiene la forma y = mx + b, donde m es la tasa de cambio de y con respecto a x, b es el valor de y en x = 0, x es una variable independiente (no depende de otras variables) ey es una variable dependiente (depende de otras variables)
Dado que f (x) = 50 + 80x, obtenemos m = 80, esto significa que el costo aumenta en 80 cada día
Three out of seven soccer players wore headbands in a soccer league. A.Write the ratio of soccer players who wore headbands to soccer players who did not. B. If there were 36 players in the league who did not wear headbands, how many players were in the league brainily
Answer:
A. 3:4
B. 63 soccer players
Step-by-step explanation:
A. If out of 7 players, 3 wore headbands, then it means 4 out of 7 did not wear headbands.
Ratio of players who wire headbands to those who didn't wear headbands would be 3:4
B. Let x represent number of players who wore headbands
Number of players who didn't wear = 36
Total number of players in the league = number of players who wore headbands + those who didn't wear headbands = x + 36
Let's find x by using the ratio generated in part A.
Ratio of players who wore head bands to players who didn't wear = 3:4 = x:36
[tex] \frac{3}{4} = \frac{x}{36} [/tex]
Cross multiply
[tex] 4*x = 3*36 [/tex]
[tex] 4x = 108 [/tex]
[tex] \frac{4x}{4} = \frac{108}{4} [/tex]
[tex] x = 27 [/tex]
Total number of players in the league = x + 36
Plug in the value of x
= 27 + 36
= 63 players
