Set h(t) equal to 4: To find the value of h(□), we need to set the function h(t) equal to 4 and solve for the variable t. h(t)=4t+20 h(□)=4 So, we set 4t+20 equal to 4 and solve for t. 41
Subtract 20 from both sides: Subtract 20 from both sides of the equation to isolate the term with t.4t+20−20=4−204t=−16
Divide both sides by 4: Divide both sides of the equation by 4 to solve for t.44t=4−16t=−4
Value of t for h(□)=4: Now that we have found the value of t, we can say that h(□)=4 corresponds to t=−4.
