Answer:
i think its number 2 hope its correct
Answer:
6+3-8-7 = 8
1+4+10-8 = 7
3-3+9+1 = 10
10-2+10-8 = 10
2+0+1+2+3 = 8
10-1-2-3+4 = 8
Step-by-step explanation:
i don't know if these are supposed to be easy or not lol but thanks for the points :p
Step-by-step explanation:
B) perpendicular and intersecting
<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>
