number of cards = 100
number less than 14 = {2,3,...,13} = 12
number perfect square = {4, 9, 16, 25, 36, 49, 64, 81, 100} = 9
so
a) probability = 12/100 = 3/25
b) probability = 9/100
Answer:
129 square inch
it is correct

X=-19°F-7°F
x=-26°F
-19°F because -24 rose up 5 before the sun set, making it -19.
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
