(
11/12) x (2/5) = (11 * 2)/(12*5) = 22/60 = 11/30

Answer:
1/2
Step-by-step explanation:
-4y = -2x + 10
y = 1/2x - 2/5
The slope is the number in front of the x, so the slope would be 1/2.
Using The Almighty Formula (attached)
Note the symbol ^ is used to denote a raise to power
Where from the equation given x^2-5x-7
With a,b,c coefficients
a=1 b=-5 c=-7
From the Almighty Formula
√b^2-4ac=√(-5)^2-4(-7)=√53
Substituting in the Almighty Formula
-(-5) ±√53/2(1)= 5±√53/2
x=5+√53/2 and x=5-√53/2
When the sides are the same legnth, that is max area
(I can find the max area with calculus but I don't think you know that)
so
if we assume that they are equal
L=W
376=perimiter
P=2(L+W)
376=2(L+W)
376=2(L+L)
376=2(2L)
376=4L
divide both sides by 4
94=L
the dimeintions are 94 by 94, if we mulipy we get 8836ft
C is answer
(note: for those people who say rectangles have to have different side legnths, that is incorrect because the requirement is 4 right angles, all squares are recangles, but not all rectangles are squares)
C is answer
Answer:
Find other solutions in explanation
x = 250
y = 1750
Step-by-step explanation:
x = cost per copybook
y = cost per pen
2. Sum of the cost of 4 copy books and 3 pen is equal to 7750
3.)
2x+y=2750 - - (1)
4x + 3y = 7750 - - - (2)
From (1)
y = 2750 - 2x
Substitute y = 2750 - 2x into (2)
4x + 3(2750 - 2x) = 7750
4x + 8250 - 6x = 7750
-2x = - 500
x = 500/2
x = 250
y = 2750 - 2(500)
y = 2750 - 1000
y = 1750
