How do you expand 4(z+2) ? sorry we had a sub in math and i was so

Two streets intersect at a 30- degree angle. at the intersection, the are four crosswalks formed that are the same length. what type of quadrilateral is formed by the crosswalks?

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

The table below shows the function f. determine the value of f(3) that will lead to an average rate of change of 19 over the interval [3, 5]. a. 32 b. -32 c. 25 d. -25
