Answer: 89,760 miles
Step-by-step explanation: 5,280*17=89,760.
Answer:
Step-by-step explanation:
Like your other question, let's break it down systematically
6x + 9y - 9(6x - 3y + 8z)
Use the distributive property
6x + 9y - <u>9(6x - 3y + 8z)</u>
6x + 9y - 54x - 27y + 72z
Match like terms
6x - 54x = -48x
9y - 27y = -18y
72z - 48x - 18y
Answer:
248
Step-by-step explanation:
A=height b times base divided by two
which is:
A= 16 times 31 divided by two
ANSWER
c. Domain: [0,18]
Range: [0,360]
EXPLANATION
The domain refers to the values of x for which the function is defined.
The given straight line graph is defined for x=0 to x=18.
Hence the domain is [0,18]
The range refers to the values of y for which x is defined.
The graph is defined for y=0 to y=360.
The range is [0,360]
Answer:
8x² - 15y² + xy
Step-by-step explanation:
(4x + 5y) (2x - 3y) + 3xy
multiplying the terms in brackets
(4x) (2x - 3y) + (5y) (2x - 3y) + 3 xy
multiplying with each terms inside the bracket
(4x)(2x) - (4x) (3y) + (5y) (2x) - (5y) (3y) + 3xy
doing the product each of the pair of terms
8x² - 12xy + 10xy - 15y² + 3xy
taking the sum of terms with coefficient "xy"
8x² - 15y² -2xy + 3xy
8x² - 15y² + xy
