Answer:
solve for x
4x-6=26
4x=26+6
x=32/4
x=8
area of rectangle=l*b
=26*14
=364
area of triangle=b*h/2
=18.4*20.4/2
=375.36/2
=187.68 m^2
for another side of a triangle
(18.4)^2+(20.4)^2=c^2
338.56+416.16=c^2
=c
27.47=c
27.5=c
now, perimeter of triangle=a+b+c
=27.5+18.4+20.4
=66.3 m^2
radius=diameter/2
=26/2
=13 ft
diameter=26 ft
circumference=2πr
=2*3.14*13
=81.64
Area of a circle=π
=3.14*(13)^2
=3.14*169
=530.66 ft^2
Step-by-step explanation:
The square root of negative numbers is either "not allowed" (Case 1) or it results in imaginary roots (Case 2).
-8+ square root of -20 /24 "not allowed," Case 1
-8+ square root of -5/6 = -8 plus or minus i times sqrt(5/6)
5√6
= -8 plus or minus i times --------- (Case 2)

Answer:
m = 8
Step-by-step explanation:
Solve for the value of the variable of <em>m</em>. Note the equal sign, what you do to one side, you do to the other. Remember to do the opposite of PEMDAS. PEMDAS =
Parenthesis
Exponent (& roots)
Multiplications
Divisions
Addition
Subtraction
.. and is the order of operation.
In this case, first, divide 4 from both sides:
(4(m - 2))/4 = (24)/4
m - 2 = 24/4
m - 2 = 6
Isolate the variable, m. Add 2 to both sides.
m - 2 (+2) = 6 (+2)
m = 6 + 2
m = 8
m = 8 is your answer.
Check. Plug in 8 to m in the equation. Remember to follow PEMDAS when solving:
4(8 - 2) = 24
4(6) = 24
24 = 24 (True).
m = 8 is your answer.
