Answer:
= 105(x+2)/33-x
Step-by-step explanation:
Given the expression
[3(x+2)*10*7]÷70 - 2(x+2)
= 3(x+2)*70÷70 - 2(x+2)
= 210(x+2)/70-2x-4
= 210(x+2)/66-2x
= 210(x+2)/2(33-x)
= 105(x+2)/33-x
Answer: The equation can be written as 8n = 99.2.
Step-by-step explanation:
In my answer, I used the variable n to distinguish itself as one side of the stop sign. 99.2 is the final perimeter in inches.
A stop sign is an octagonal shape (otherwise, it is made up of 8 equal sides). Therefore, with this information, you can interpret that the length of one side would be equal to the length of all of the other sides.
Hence, the answer can be represented as 8n = 99.2.
Answer:
<h3>
-2a³ + 9a² + 6ab² + 45a + 18b² </h3>
Step-by-step explanation:
(a + 3)×(−2a² + 15a + 6b²) =
= a×(−2a² + 15a + 6b²) + 3×(−2a² + 15a + 6b²) =
= -2a³ + <u>15a²</u> + 6ab² - <u>6a²</u> + 45a + 18b² =
= -2a³ + 9a² + 6ab² + 45a + 18b²
Trick question: Jessica still only drank 3.5 glasses of water it doesn’t matter what her sister did it does not effect what Jessica drank.
Converting to base 10 can be done easily by writing a sort of digit expansion. In base 6, this number literally means
Simplifying this gives the value in base 10.
