Answer:

C, (12, -1)

Step-by-step explanation:

x - 2y = 14

x + 3y =9

Add 2y to both sides

x = 14 +2y

Substitute this into the second equation and solve

14 + 2y + 3y = 9

5y = 9 - 14 = -5

5y = -5

y = - 1

(you don't need to do this step because there is only one equation with y=-1, but just in case...)

Plug y into the first equation:

x - 2(-1) = 14

x - (-2)= x+2

x + 2 =14

x =12

Therefore, the answer is (12, -1)

The answer is C

The sides of a rectangle measure 14 and 21. The perimeter of a similar rectangle is 40. What are the lengths of its Sides

Ipatiy [6.2K]

Answer:

8 and 12

Step-by-step explanation:

The perimeter of the given rectangle is ...

P = 2(L +W)

P = 2(14 +21) = 2(35) = 70

The scale factor to the similar triangle is ...

similar perimeter/original perimeter = 40/70 = 4/7

The dimensions of the similar triangle are the original triangle dimensions multiplied by this scale factor:

(14)(4/7) = 8

(21)(4/7) = 12

The sides of the similar triangle are 8 and 12.
