D. Translation and dilation, no
You know it’s a translation because first it’s not in the same spot and second it is an answer choice in all the answer
You know it’s not a reflection because the shape looks the same and every point faces the same direction
So that is means it’s a dilation.
You also know that it’s a dilation because there is a size difference between the two.
Lastly because of the size difference, they aren’t congruent because congruent means the same and they aren’t the same size

Use the quadratic formula to solve, 2x^2=7x+6 Leave your answer in simplified radical form.
Lena [83]
2x² = 7x + 6

Subtract both terms so that we can get 0 on one side. 

2x² - 7x - 6 = 0

Find what factors of - 12 (2 * - 6) add up to be - 7. It's - 4 and - 3. 

2x² - 4x - 3x - 6 = 0
2x(x - 2) - 3(x - 2) = 0
(x - 2)(2x - 3) = 0

Now set each equal to 0.

x - 2 = 0
x = 2

2x - 3 = 0
2x = 3
x = 3/2

x = 3/2, 2

Dylan, Alan, Bruce, and Cecil are brothers. Dylan weighs d pounds. Alan weighs 3 pounds more than twice what Dylan weighs. Bruce
vaieri [72.5K]

Answer:

Part A: 2D + 3 = A

Note: I have likely given you the answer to the whole problem. See below.

Step-by-step explanation:

Givens

  • Alan = A
  • Bruce = B
  • Cecil = C
  • Dylan = D

Comment

You have to pay the most attention to Alan and Bruce. Once you have equations for those two. Cecil's weight is just the sum of those two.

<em>Alan</em>

Alan = Twice*Dylan + 3 or

A = 2*D + 3

<em>Bruce</em>

Bruce = three * Dylan - 12

B = 3*D - 12

<em>Cecil</em>

Cecil = Alan + Bruce

C = A + B

Note

The last equation shows you how to combine the first two.

C = A + B

A = 2D + 3

B = 3D - 12

C = 2D + 3 + 3D - 12

C = 5D - 9
