Answer:
1.56666666667 MPH simplified its 1.5MPH
Step-by-step explanation:
divide 94 by 60 to get the constant speed of mph.
The 60 inch is diagonal of or the hypotenuse of the TV so we are going to use a^2+b^2=c^2 and let width to be a, then we solve the problem.
a^2=c^2-b^2
oh, take the square root of both sides.
a=((c^2-b^2))^(1/2)
plug 60 for c, 32 for b, and the Width is equal to 50.75 for significant figures.
<span>(a+b)(c+d)=ab+ad+bc+bd
(5k-4)(4k-5)=20k^2+-25k-16k+20=20k^2-41k+20
Hope this helps!</span>
