Whats the solution to 5x+4> 11-2x

Which expression gives the area of the triangle shown below

Given abcd ac=38 and ae=3x+4 find the value of x

What is the explicit formula for this sequence? -7, -4, -1, 2, a.) an = 8 + (b - 1)3 b.) an = -7 + (n - 1)3 c.) an = 3 + (n -1) (-7) d.) an = -7 + (n - )
