A =s^2 since the wall is square
78 =s^2
take the square root of each side
sqrt(78) = s
s=8.83 ft
Choice B
<span>a1 = 3
an = a (n-1) +7</span>
2.6 + 9.2 x 4 would equal, <u><em>39.4</em></u>
The inverse of this function is g(x)=9x+2. if this doesn’t work, try g(x)=9x-2 :)
Answer:
angle D equal to 3 X + 20 + 7 x minus 3 x
=90 degree equal to x minus 3 X + 20
7 X equal to 70 X equal to 10
