Answer:

  Perimeter: 17 inches

  Area: 8 square inches

Step-by-step explanation:

The ratio of perimeters is the same as the similarity ratio.

  JKLM perimeter / ABCD perimeter = P/68 = 1/4

Multiplying by 68, we get ...

  P = 68/4 = 17 . . . . inches

__

The ratio of areas is the square of the similarity ratio.

  JKLM area / ABCD area = A/128 = (1/4)^2

Multiplying by 128, we get ...

  A = 128/16 = 8 . . . . square inches

__

Perimeter = 17 inches

Area = 8 square inches

Which of the following shows the factors of 5x2 + 17x + 6? A. (5x + 1)(x + 6) B. (5x + 2)(x + 3) C. (5x + 3)(x + 2) D. (5x + 6)(
zysi [14]

Answer:

B. (x+3)(5x+2)

Step-by-step explanation:

The given quadratic trinomial is;

5x^2+17x+6

Comparing this to ax^2+bx+c, we have a=5,b=17,c=6.

ac=5\times6=30

Two factors of 30 that add up to 17 is 15  and 2.

We split the middle term to obtain;

5x^2+15x+2x+6

We factor by grouping;

5x(x+3)+2(x+3)

Factor further

(x+3)(5x+2)

The correct answer is B.
