Answer: (13x+8)(13x-8) is the answer
Answer: The actual area of the base of the building = 4418 square feet.
Step-by-step explanation:
Dimensions of model: 2 inches in length and 1 inch in width.
The scale on the model is 1 inch = 47 feet.
Actual length = 2 x (47 feet) = 94 feet
Actual width = 1 x 47 feet = 47 feet
Actual area of base of building = (Actual length) x (Actual width)
= 94 x 47 square feet
= 4418 square feet
Hence, the actual area of the base of the building = 4418 square feet.
Step-by-step explanation:
"The probability of drawing a red ace followed by another ace of any color without replacement."
There are 4 aces total, 2 of which are red. After the first red ace is drawn, there will be 3 aces left. So the probability is:
P = (2/52) (3/51)
P = 1/442
"The probability of drawing a king followed by a queen with replacement."
There are 4 kings and 4 queens. So the probability is:
P = (4/52) (4/52)
P = 1/169
"The probability of drawing a 3 or a 5 followed by a 4 or a 6 with replacement."
There are 8 cards that are either 3 or 5, and 8 cards that are either 4 or 6. So the probability is:
P = (8/52) (8/52)
P = 4/169
"The probability of drawing a spade followed by a jack of any color with replacement."
There are 13 spades, and 4 jacks. So the probability is:
P = (13/52) (4/52)
P = 1/52
Answer:
You use the product of powers law of exponents to combine the exponents; this law says to add the exponents.
