12 hours worth $87
1 hour would be $87/12 = $7.25
9 hours worth $65.25
1 hour would be $65.25/9 = $7.25
The constant of proportionality is $7.25 per hour.
Answer:
f(x)= 2x^4 - x^3=24 -18x^2 + 9x= 45 45-24=21
Step-by-step explanation:
just multipkye that
The sides of a right triangle can always be expressed as:
h^2=x^2+y^2, where h is the length of the hypotenuse and x and y are the side lengths.
If we are to assume that "a" is a side length then 17 or "c" must be the hypotenuse so:
17^2=11^2+a^2
a^2=289-121
a^2=168
a=√168
a≈12.96 (to nearest hundredth)
Note we knew this assumption because of the answer choices, but technically, "a" COULD have been the hypotenuse without this implicit suggestion making:
a^2=17^2+11^2
a^2=410
a=√410
a≈20.25 (to the nearest hundredth)
Of course the above is not relevant to this particular question but be aware that you won't always be given answer choices to make the assumption of which side is the hypotenuse...
Hey there!
(8 * 7 - 3) * 7
= 8(7)(7) - 3(7) ⬅️ POSSIBLY BE AN EQUIVALENT EXPRESSION
= 56(7) - 3(7)
= 392 - 3(7)
= 392 - 21
= 371 ⬅️ OVERALL ANSWER/EQUATION ANSWER
Most likely your answer should be:
• 8(7)(7) - 3(7)
• 56(7) - 3(7)
• 392 - 3(7)
• 392 - 21
EITHER OF THESE SHOULD WORK ⬆️
Good luck on your assignment and enjoy your day!

Answer: C
Step-by-step explanation: since the x’s are common terms, you just add them together
