Kerry wants to remodel his house by knocking down a wall between two adjacent rectangular rooms. The dimensions of the rooms are shown in the blueprint. (2x + 7) (2x -1) (x + 3) (x + 3) Which expression models the area of the new room once the wall is knocked down? A) 6x + 12 B) 4x2 + 18 C) 4x2 + 18x + 18 D) 4x2 + 20x + 24

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
