Answer:
Length of rectangle = 10 mWidth of the Rectangle = 8 mStep-by-step explanation:
Given :-
Length of a Rectangular garden is 2m greater than the width .Area of garden = 80 m²To Find :-
Dimensions of the gardenSolution :-
Let's assume:
Width of the rectangle = xLength of the rectangle = x + 2We know that,
Area of rectangle = Length × Width↠ (x)(x + 2) = 80
↠ x² + 2x - 80 = 0
↠ x² + 2x - 80 = 0
↠ x² + 10x - 8x - 80 = 0
↠ x(x +10) -8 (x + 10) = 0
↠ (x-8) (x + 10) = 0
↠ x = 8 or -10
↠ x = 8
Hence,
Width of the rectangle = x = 8 mLength of the rectangle = x + 2 = 10 mAnswer:
Given:-
Length of rectangular garden is 2m longer than its widthArea of Rectangular garden is 80m²To Find :-
Dimensions of Rectangular gardenSolution:-
Let the width be x and length be x + 2According to the question ,
Area = 80m²
putting the known values ,
(X)(X+2) = 80m
x² +2x - 80= 0
x² +10x-8x -80m= 0
x(x + 10) - 8(x+10) = 0
(x-8) = 0 ; (x+10) = 0
X = 8 ; X = -10
As dimensions can not be negative so , X = 8Length = X + 2 ; 10 m
Width = X ; 8 m

What is the quotient? startfraction 2 m 4 over 8 endfraction divided by startfraction m 2 over 6 endfraction
The Quotients of the given expression (2m + 4) / 8 divided by (m + 2)/6 would be 3/2.
What are the Quotients?Quotients are the number that is obtained by dividing one number by another number.
Dividend ÷ Divisor = Quotients
(2m + 4) / 8 divided by (m + 2)/6
= (2m + 4) / 8 ÷ (m + 2)/6
= (2m + 4)/8 x (6 / (m + 2) )
= (m + 2)/4 x 6/(m + 2)
= 6/4
= 3/2
Thus, the quotients will be 3/2.

PEMDAS
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis, Exponents (& Roots), Multiplication, Division, Addition, Subtraction.
First, divide 3 from both sides of the equation:
[tex]\frac{(3x^2)}{3} = \frac{(48)}{3}[/tex]
[tex]x^{2} = \frac{48}{3}\\ \\x^2 = 16[/tex]
Next, isolate the variable, x, by rooting both sides of the equation:
[tex]\sqrt{x^{2} } = \sqrt{16}\\ x = \sqrt{16} = \sqrt{4 * 4}[/tex]
x = ±4
C) ±4 is your answer.

You are riding the bus to school and you realize it is taking longer because of all the stops you are making. The time it takes to get to school measured in
minutes, is modeled using the function g(x) = x - 3x + 4x - 5, where x is the number of stops the bus makes. If the bus makes 2 stops after you board, how
long does it take you to get to school?
AA. 1 minute
B. 3 minutes
C. 7 minutes
D. 11 minutes
Answer:
-1
Step-by-step explanation:
g(2) = (2) - 3(2) + 4(2) - 5
g(2) = 2 - 6 + 8 - 5
g(2) = 2 - 6 + 3
g(2) = 2 - 3
g(2) = -1

Answer:
800 bacteria
Step-by-step explanation:
Answer of this question depend upon number of hours at the end of day
Let Take Full Day of 24 hrs
Colby bacteria will doubled 12 times ( doubled once in 2hrs => 24/2 = 12)
Colby bacteria at end of day = 50 * 2¹²
Jaquan bacteria will doubled 8 times ( doubled once in 3hrs => 24/3 = 8)
Let say Jaquan bacteria at start of Day = J
Jaquan bacteria at end of day = J * 2⁸
Equating Both
J * 2⁸ = 50 * 2¹²
=> J = 50 * 2⁴
=> J = 50 * 16
=> J = 800
Jaquan will start with 800 Bacteria

First of all we need to label the missing sides ,please check the figure I provided for that :
x = 37 - (10+ 15) = 37 - 25 = 12
z = 10
y = 2 × 10 = 20
The shade does area = area of the whole rectangle − the white area
= 37 × 20 − [ (15×20)÷2 + (10×12)÷2 ]
= 740 − [ 150 + 60 ]
= 740. − 210
= 530

Answer:
173 degrees
Step-by-step explanation:
we know AED + AEB + BEC + CED = 360
AEB = 112
to find BEC, we have B + BCE + BEC = 180 because they form a triangle. so BEC = 180 - B - BCE = 180 - 73 - 79 = 28
to find CED, follow the same steps as BEC: 180 - 37 - 96 = 47
now AED = 360 - AEB - BEC - CED = 360 - 112 - 28 - 47 = 173

[tex]-38x+43=-40x-57[/tex]
Answer:
x=-50
Step-by-step explanation:
I used the method of balancing equations:
Add -40x to both sides
-38x+43 + 40x = -40x-57+40x
Simplify:
2x+43 = -57
Subtract 43 from both sides:
2x+43 -43 = -57 -43
Simplify:
2x = -100
Solve for x
2x÷2 = -100÷2
x = -50
Hope this helped and brainliest please
Answer:
Solution of equation ( x ) = -50Step-by-step explanation:
In this question we have given an equation that is -38x + 43 = -40x - 57 . And we have to find the solution of this question that means we have to find the value of x .
So let's start our Solution : -
[tex] \hookrightarrow \: -38x+43=-40x-57 [/tex]
Step 1 : Subtracting 43 on both sides :
[tex] \hookrightarrow \: \: - 38x + \cancel{43} - \cancel{43 }= - 40x - 57 - 43[/tex]
On calculating further , We get :
[tex] \hookrightarrow \: - 38x = - 40x - 100[/tex]
Step 2 : Adding 40x on both sides :
[tex] \hookrightarrow \: - 38x + 40x = - \cancel{40x} - 100 + \cancel{40x}[/tex]
On calculating further , We get :
[tex] \hookrightarrow \:2x = - 100[/tex]
Step 3 : Dividing by 2 on both sides :
[tex] \hookrightarrow \: \frac{ \cancel{2}x}{ \cancel{2} } = \cancel \frac{ - 100}{2} [/tex]
On calculating further , We get :
[tex] \hookrightarrow \: \purple{\boxed{\frak{x = - 50}}}[/tex]
Henceforth , value of x is -50 .Verifying : -
Now we're verifying our answer by substituting value of x in given equation . So ,
-38x + 43 = -40x - 57-38 ( -50 ) + 43 = -40 ( -50 ) - 571900 + 43 = 2000 - 571943 = 1943L.H.S = R.H.S Hence, Verified.Therefore , our solution is valid .

Answer: Reflection across the y-axis
Step-by-step explanation:
A reflection over a y-axis means that the original point (x, y) becomes (-x, y)
The original point (-2, 1) should become (-(-2), 1) which becomes just (2, 1).
(2, 1) is the reflected point hence it is a reflection across the y-axis
A tree is 30 feet tall. You measure the angle of elevation from the ground where you are
standing to the top of the tree and get 50 degrees. How far away from the tree are you?
Step-by-step explanation:
given :
h = 50 ft
the angle if elevation , a = 50°
find :
the distance , d =?
the answer:
tan a = h/d
d = h /tan a
= 50/ tan 50°
= 50 / 1,19
= 42,02 ft
Let's see
