Answer:
B, An n-by-m array.
Step-by-step explanation:
when working with 2D arrays, rows come first and then columns. so all options here are correct except option B
(A) 240 (B) 220 (C) 280 (D) 210
The axiom applied in all the provided equations is the Commutative Property, which is a fundamental property of addition and multiplication in mathematics, stating that the order of operands can be changed without altering the outcome.
The axiom used in the provided equations is the Commutative Property of Addition and the Commutative Property of Multiplication.
a. The equation 3 + 5 = 5 + 3 represents the Commutative Property of Addition, which states that the order in which numbers are added does not affect the sum. In this case, it shows that changing the order of the addends does not change the result.
b. The equation 3x^2 + 5y^2 = 5y^2 + 3x^2 demonstrates the Commutative Property of Addition for algebraic terms. It shows that changing the order of the terms in an addition operation does not alter the result.
c. In the equation Zxy + 5 - 3cd = Zxy - 3cd + 5, the Commutative Property of Addition is evident, illustrating that the order of the terms in an addition operation can be rearranged without changing the result.
d. The equation (5c + 3x) + Zy = 5c(3x + Zy) demonstrates the Commutative Property of Multiplication. It shows that changing the order of factors in a multiplication operation does not affect the product.

Triangle angle-sum theorem
9514 1404 393
Answer:
s = 53°
Step-by-step explanation:
The sum of angles in a triangle is 180°.
(s -20°) +(2s) + 41° = 180°
3s +21° = 180° . . . . . . . . . . collect terms
s +7° = 60° . . . . . . . . . . divide by 3
s = 53° . . . . . . . . . . subtract 7°
