Can you please help me with these questions? Thanks
The equation for an object's height H in meters t second after launch from a 58.5 meter tall building is given by: H = -4.8t^2 + 19.6t + 58.8 a. Find the height 4 seconds after launch. b. Find the time when the object hits the ground. A garden measures 10 meters by 8 meters. You are working as a landscaper and going to add walkway around the whole thing, as in the image. If the total area (including walkway) is 224 square meters, what is x (the width of the walkway)? A number has the following property: The product of seven less than the number with three more than twice the number equals -26. Find all possible values for this number.
