14. The diagonals of square ABCD intersect at E. If AE = 2, find the perimeter of ABCD.

lutik1710 [3]

Answer:

B, $8\sqrt{2}$

Step-by-step explanation:

Diagonals of a square are congruent so AC= 4

using pythagorean theorem we can then do $x^{2} +x^{2}$ = $4^{2}$

$2x^{2} = 16\\x^{2} =8\\x=\sqrt{8} \\x=2\sqrt{2}$

Then for perimeter we times the $2\sqrt{2}$ by 4 and get

$8\sqrt{2}$

Andrew is two years older than Beatrice, and Chris is three years younger than Beatrice.

In-s [12.5K]

Answer:

Beatrice's age is 34

Step-by-step explanation:

Beatruce = B

Andrew = B+2

Chris= B-3

B+(B+2) +(B-3 )= 67-B

3B-1 = 67-B

2B -1 = 67

2B= 68

B = 34

Beatrice is 34

Andrew is 36 (34+2)

Chris is 31 (34-3)

36+31 = 67
