Answer:
A. x-6
Step-by-step explanation:
The area of a square is given by the expression square inches. Now we need to find an expression that represents the length of one side of the square, in inches. To do that we need to factor .
Since area of square is given by (side)^2
Hence one side of square is (x-6).
So choice A. x-6 is correct.
If the value of x decreases, the value of y decreases
Answer:x=35.6
Step-by-step explanation:
look at the left triangle. I hope you're familiar with SOH, CAH and TOA.
sin 60°=O/(11√7)
so O= (11√7)sin 60°
now look at the triangle on the right.
cos 45=adjacent/x
cos 45=[(11√7)sin60°]/x
therefore, using ur calculator, you'll get x= [(11√7)sin60°]/cos 45
x=35.64407384
You should multiply 20 time 8 to get your answer
This question can be solved using the Herons equation where
A = SQRT [s*(s-a)*(s-b)*(s-c)]
A = area of the triangle
a, b and c are the sides of the triangle
s = (a+b+c)/2
Since we are given the area, we can express "s" as a function of the third side c. This can be substituted in the original equation so as to obtain an expression to solve for the third side c
s = (4+10+c)/2 = (14+c)/2
using the solver function of the calculator or MS Excel, the third side is 7.21 units
