Answer:
10x + 12 and 6x² + 11x - 7
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is length and w is width )
= 2(2x - 1) + 2(3x + 7) ← distribute parenthesis
= 4x - 2 + 6x + 14 ← collect like terms
= 10x + 12
--------------------------------------------------
The area (A) of a rectangle is calculated as
A = lw
= (2x - 1)(3x + 7) ← expand using FOIL
= 6x² + 14x - 3x - 7 ← collect like terms
= 6x² + 11x - 7
B. 0 ÷ 28 = 0
Is the mathematical statement that is true.
Rule of ZERO. Zero(0) can be a numerator with non-zero denominator. Its overall value is equal to 0.
Rule of ZERO. A fraction with a denominator of ZERO is not a legal fraction. This is because the overall value of a number divided by zero is undefined.
28 + 0 = 28 not 0.
28 - 0 = 28 not 0.
28 ÷ 0 = ERROR! not 0. value is undefined
The factor "x" is the number 6
