Answer:
×=11
Step-by-step explanation:
-2(3×-1)-2=-3-5×+13
-6×-1-2×=-3-5×+13
-6×+2×+5×=1-3+13
1×=11
×=11
Using the quadratic formula:
16t^2-144t+H=0
t=(144±√(144^2-4*16*H))/32
t=(9/2) ±<span>√(64(324-H))/32
t=(9/2) </span>±(8<span>√(324-H))/32
t=4.5</span>±0.25<span>√(324-H)
You cannot simplify it any further with H as a variable
Hope this helps!</span>
