By definition, the area of a triangle is given by:

 A = (1/2) * (b) * (h)

 Where,

 b: base

 h: height

 The area of the original triangle is 3 mm² and is dilated by a factor of 6. We have then

 A = (1/2) * (6b) * (6h)

 A = (1/2) * (b) * (h) * (6) * (6)

 A = 3 * (6) * (6)

 A = 108 mm²

 answer

 The area of the dilated triangle is 108 mm²

42.5p=c

You get you get the number 42.5 since you know 10 people paid 425, you would divide 425 by 10 to know how much every person paid.

M is representing the amount of money each person paid

(M)10=425
M=425/10
M=42.50 <- since it’s about money

Each person paid $42.50


The cost for 15 people is $637.50.

42.5p=c
42.5(15)=637.5

Answer:

98

Step-by-step explanation:

ABSOLUTE BRACKETS MEAN ABSOLUTE VALUE- this means that negatives will come out as positives since their absolute values are the same. So |-9| is just 9.

|-81-17| (apply the rule I just gave you)

|81+17|
