Step-by-step explanation:
Perimeter of a Rect.= 2(l+b)
b= x
l= 2x
Equation
152= 2(2x+x)
152= 2(3x)
152= 6x
x= 25.33
2x= 50.66
Therefore length is 50.66m and breadth is 25.33m
Answer:
Step-by-step explanation:
cos (2α)*sin (α-β)-cos(β-α)*sin(2α)
cos (β-α)=cos {-(α-β)}=cos (α-β)
[cos (-x)=cos x]
sin(α-β)*cos (2α)-cos (α-β)*sin (2α)=sin (α-β-2α)=sin (-α-β)
=sin {-(α+β)}
=-sin (α+β)
Answer: 52.77876 in
Explanation: C=2πr=2·π·8.4≈52.77876 in
The answer would be -15x+36. To solve this equation, you would first use distributive property and distribute the -9 to the values inside the parentheses (or multiply them). So, you would multiply -9 and x and -9 and -4 to get -9x+36-6x. Then, you combine like terms, which are -9x and -6x to get -15x. You can't simplify any further without knowing the value of x. Hope this helps!
