Answer:
The Cardboard dimensions are 13cm in length and 12cm in breadth
Step-by-step explanation:
We can use Pythagoras Theorem to find the length the Cardboard (a²+b²=c²). Let A be 5 and B be 12, we find that C is equivalent to 13. The height is 12, thus the breadth of the Cardboard is also 12. Hope this helps :)
Hi there,
2 (x +5) - 3 = -(2x + 1) + 1
2x + 10 - 3 = -2x - 1 + 1
2x + 10 - 3 = -2 - 1 + 1
2x + 7 = -2x
2x + 2x = -7
4x = -7
Hence, X= -7/4
Hope this helps :)

Answer: It already tells you what DE= 60
Step-by-step explanation:
Since F is the midpoint of DE that means DF=FE
So create equation 
When DF and FE is added your answer should equal DE
So you write the equation 
to find x and once x is found substitute your answer for x
subtract 12 on both sides 36-12= 24
subtract 2x on both sides 4x-2x=2x
divide 2 into both sides 24/2=12 x=12
4x12=48+12=60 2x12=24+36=60

Answer:
∠ 3 = 25°
Step-by-step explanation:
The sum of the 3 angles 85, 2x and x - 10 are a straight angle = 180°
85 + 2x + x - 10 = 180, that is
3x + 75 = 180 ( subtract 75 from both sides )
3x = 105 ( divide both sides by 3 )
x = 35
Thus x - 10 = 35 - 10 = 25
∠ 3 and x - 10 are Alternate angles and congruent, thus
∠ 3 = 25°
