We are given
length of rectangle is 4x-3
width of rectangle is 6x+9
we know that
Area of rectangle = length of rectangle*width of rectangle
so, we can plug value
and we get
now, we can distribute it
now, we can simplify it
...............Answer
Well idk about #16 but #20 I can answer it OK look, number 20 , Y represent height X represent time OK, number a is asking for maximum height , the ball will reach the maximum height when time equal zero so Y = -16(0)^2 + 15(0) + 6 which equals 6 so maximum height is 6 feet, and as for number b , when the ball hit the ground the distance will equal zero so Y = 0 , so by factorizing. the given equation find the values of X, U will probably find 2 values one in +ve and one in -ve take the positive and neglect the -ve and we are done
C and D will be the answers
It would be D hope this helps
