Answer:
The perimeter is the length of the outline of a shape.
No. This is because the two smaller lengths must be greater than the largest length (7+3=10) this is less than 13 meaning the triangle won’t work
This is honestly simple but we all need help! The answer is 55,053. Hope this helps! =3
Answer:
12 x 3 , 2 x 18
Step-by-step explanation:
9x4= 36. You need to find two numbers that multiply to equal 36. In this case, you can do 12 x 3, and 2 x 18
Answer:
The generalisation she can make from her work is that the other two angles of the quadrilateral are supplementary i.e their sum is 180°
Step-by-step explanation:
We are given the following from what she knows
m∠3=2⋅m∠1... 1
m∠2=2⋅m∠4 ... 2
m∠2+m∠3=360 ... 3
From what is given, we can substitute equation 1 and 2 into equation 3 as shown:
From 3:
m∠2+m∠3=360
Substituting 1 and 2 we will have:
2⋅m∠4 + 2⋅m∠1 = 360
Factor out 2 from the left hand side of the equation
2(m∠4+m∠1) = 360
Divide both sides by 2
2(m∠4+m∠1)/2 = 360/2
m∠4+m∠1 = 180°
Since the sum of two supplementary angles is 180°, hence the generalisation she can make from her work is that the other two angles of the quadrilateral are supplementary i.e their sum is 180°
