Answer:
Step-by-step explanation:
<u>Rectangle has equal diagonals:</u>
<u>Substitute and solve for x:</u>
- 5x + 1 = 8x - 32
- 8x - 5x = 1 + 32
- 3x = 33
- x = 11
<u>Find the length of the diagonals:</u>
- JL = MK = 5*11 + 1 = 56 units
<u>Diagonals of the rectangle bisect each other:</u>
- KN = MK / 2 = 56/2 = 28 units
So for the two equations: Not sure how hard you want them but....
15+1=16 and 13+ 18=21
For the open equation.
2x + x(5+7)=105
Answer:
Step-by-step explanation:
if the measures both the acute angles of a right angled triangle are equal ( 45° ), then the two smaller sides are equal.
so, x = 6
now, by pythagorus theorem :

( because x = 6 )

Answer:
Step-by-step explanation:
= 5.43 × 101
(scientific notation)
= 5.43e1
(scientific e notation)
= 54.3 × 100
(engineering notation)
(one)
= 54.3
(real number
Subtract 23.5 from 36.9 which gives you 13.4. The differences in temperature is therefore 13.4
