Answer: The required length of steel is 270 cm.
Step-by-step explanation:
Since we have given that
Number of stems = 6
Length of each stem = 45 cm
So, we need to find the length of steel used in the frame.
So, Length of steel = Number of stems × Length of each stem
So, the length of steel becomes

Hence, the required length of steel is 270 cm.
Intersection of E and A: E n A = { 8 }
Union of E and A : E U A = { -2, 3, 0, 6 , 8 }
<em><u>Solution:</u></em>
<em><u>The sets E and A are given below:</u></em>
E = { -2, 3, 8 }
A = { 0, 6 , 8 }
<em><u>Find the intersection of E and A</u></em>
Intersection of E and A means that, set containing all elements of E that also belong to A
Therefore,
From sets E and A,
E n A = { 8 }
<em><u>Find the union of E and A</u></em>
union of E and A contains all elements of set E and set A
E U A = { -2, 3, 0, 6 , 8 }
Answer: y=3
Subtract the bottom left of the triangle from the number at the top of the triangle. Then that number is multiplied by the number at the bottom right of the triangle.
To solve:
6-5=1
1•3=3
y=3
