3/5×1/3=1/5×1/1=1/5 so 1/5 is you answer
4+(-6)/(-2) = 7
5/2+(-3/2)=1
-3/4-5/6 = 1.58
5/8(-3/5) = -3/8
To find the side lengths, you have to factor 4x^2 + 28x + 49. This equation factored is (2x+7)(2x+7), so each side length is (2x+7) feet.
In order to solve for the area of the triangle with the
given dimensions, we use the equation
<span> A
= ac(cos b)/2</span>
Substituting the known values,
<span>
A = (11 cm)(18 cm)(cos 104o)/2 = 23.95 cm2</span>
<span>Thus, the answer is the third choice. </span>
