Step-by-step explanation:

<u>Given coordinates of the rectangle ABCD:</u>

  • A(0, 0), B(a, 0), C(x, y), D(0, b)

Lets first find coordinates of C

We can see that A and B are on same line horizontally, so C and D will be on the parallel line

The distance AB and CD are equal also distance AD and BC are equal, therefore

  • AB = a - 0 = a, CD = a
  • AD = b - 0 = b, BC = b

<u>So the coordinates of C are:</u>

  • x = a, y = b

<u>Now the diagonals:</u>

  • AC = √(a-0)² + (b-0)² = √a²+b²
  • BD =√(0-a)² + (b -0)² = √a² + b²

Since AC = BD, we can state they are congruent

C.
l b +8 l = 6 (divided both side by 5)
set b + 8 = 6 or b + 8 = -6 (because this is an absolute value)

The dividend is a factor of 60. The divisor is a factor of 18. The quotient is a multiple of 3. Use the numbers to find one poss
Diano4ka-milaya [45]

Answer:

A possible solution is 60/2 = 30

Step-by-step explanation:

The given parameters are;

The dividend is a factor of 60

The divisor is a factor of 18

The quotient is a multiple of 3

The dividend is the amount divided

The dividend is the number that is dividing the dividend

The quotient is the result of the division operation

The given numbers to use are 60, 2, 30, and 18

Therefore one possible solution is 60/2 = 30

The dividend = 60 which is a factor of 60 (60 × 1 = 60)

The divisor = 2 which is a factor of 18 (2 × 9 = 18)

The quotient = 30 which is a multiple of 3 (3 × 10 = 30)

Three Friends all have ages that are consecutive integers. The sum of their ages is 48. What is the age of the oldest friend?
Reptile [31]
Consecutive integers = in this situation double-digit whole numbers So as there are 3 of them let's say 2 are 11 because that would be the highest consecutive number so 11+11= 22 and 48-22=26 so the three have the ages of 11,11,26 and the oldest would be 26 ;)
