Answer:
x = -7 1/6
Step-by-step explanation:
x + 4 1/3 = -2 5/6
x = -7 1/6
Is this <ABD?
if so, all lines tangent to a circle, its point of tangency is perpendicular to the center of the circle. So <ABD = 90 degrees
<span>This problem is solved using the chain rule.
the area of the square is f(t) and the length of the side is g(t)
f(t)=g(t)^2
g'(t)=5
Using the chain rule
f'(t)=2*g(t)*g'(t)
The value of g(t) is sqrt(49) which is 7.
g'(t) is given as 5 cm/s
f'(t)=2*7*5=14*5=70cm^2/s</span>
The first one is d and the second is b!! also i recommend downloading mathpapa it will really help u :D
