Plzzz Helppp!! (Question 1)
What values of X and Y satisfy the system of equations 8x + 9y = -3
6x + 7y = 1

(Question 2)
What is the system of equation
9x + 8y= 3
6x-12y=-11

Distance is always positive

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
