Answer:
The length for a rectangle with a perimeter of 34 units and a width of 6.5 units would be 10.5 units.
Step-by-step explanation:
To find the length, you can use the equation [34 - (6.5 x 2) ÷ 2 = the length]. So, 6.5 x 2 = 13, then 34 - 13 = 21, finally, 21 ÷ 2 = 10.5 . So the length of the rectangle is 10.5 . To double check, (6.5 x 2) + (10.5 x 2) (=) 34. So this answer is correct.
Answer:
The answer to your question is letter D
Step-by-step explanation:
Data
P1 (3, 10)
P2 (-1, 6)
Process
1.- Calculate the midpoints
Xm = (x1 + x2)/2
Ym = (y1 + y2)/2
x1 = 3 y1 = 10
x2 = -1 y2 = 6
Xm = (3 - 1)/2
= 2/2
= 1
Ym = (10 + 6)/2
= 16/2
= 8
2.- Write the coordinates of the center
C = (1, 8)
Answer:
AC = 25
Step-by-step explanation:
Since ∠A = ∠C then the triangle is isosceles, thus BC and AB are congruent, that is
BC = AB, substitute values
7x - 1 = 5x + 5 ( subtract 5x from both sides )
2x - 1 = 5 ( add 1 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Hence
AC = 6x + 7 = (6 × 3) + 7 = 18 + 7 = 25
