question 2 (14 point)
a pre-image triangle with a base of 4 and a height of three is dilated by a scale factor of 3. what is the are of the image.
question 2 options:
the area of the triangle is 12 which makes the new image 108.
the area of the triangle is 6 which makes the new image 18.
the area of a triangle is 6 which makes the new image 54.
the area of the triangle is 12 which makes the new area 48.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

answer:

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21  

-7 + ? = 21

-7 + 28 = 21
