Answer:
156 pieces of art is in one classroom alone
Step-by-step explanation:
take 641+490=1,131
then times 1,131 times 8 which gives u 9,048
then divide 9,048 by 58 for the classrooms which gives u 156
Answer:
The vertex form will be:
Step-by-step explanation:
The equation of the vertex form of a quadratic equation is given by:
Where:
a is a coefficient
h is the x value of the vertex
k is the y value of the vertex
To completing the square we just need to add and subtract the square of the term with x divided by 2.
Finally, the vertex form will be:

Answer:
29 inches
Step-by-step explanation:
pythagoras theorem : 20^2 + 21^2 = \sqrt{841}
22 True For all real Numbers A and B, A - B = -B + A
23 True For all real Numbers P, Q, and R, P - Q - R = P - R - Q
24) True For all real Numbers X, Y, Z and (X + Y ) + Z = Z + (X + Y)
25) False For all real Numbers M and N, M/M * N = N/N ==> Example: 5/5 * 3 ≠ 3/3 * 5
26) Examples:
Counterexamples =====> 5 - 0 = 5; 5/1 = 5
5 - 3 ≠ 3 - 5; (5 - 3 ) - 2 ≠ 5 - (3 - 2 );
6/3 ≠ 3/6; (24/6 )/2 ≠ 24/ (6/ 2 )
Hope that helps!!!! : )
