In the figure above AB = 4x + 6 and BC = 7x + 15. If AC = 120, find the length of segment AB.
Mrac [35]

Answer:

x = 9

Step-by-step explanation:

AB = 4x + 6 and BC = 7x + 15  AC is the sum of AB and BC

so 4x + 6 + 7x + 15 = 120 add like terms

11x + 21 = 120 subtract 21 from both sides

11x = 99 divide both sides by 11

x = 9

A prism with a base area of 5 ft² and a height of 10 ft is dilated by a factor of 6/5 . What is the volume of the dilated prism?
ludmilkaskok [199]
The formula to find the volume of a prism is V=Bh (Volume = Base x height). Let's plug in the dimensions you were given:

V=Bh
V=(5)(10)
V=50 {tex] ft^{2} [/tex]

To find the new volume of the dilated prism, cube the dilated factor, then multiply by the volume you just found (old volume):

New Volume = (x^{3})(Old Volume)
V = (\frac{6}{5})³·50
V = (\frac{432}{5}
V = 86.4
