The total amount of little cubes on the surface is 600, since there is 100 cubes on one face and there are 6 faces (6 times 100). But, there is overlap because the cubes on the edges are painted on more than one edge. There are 12 edges, and every edge has 10 that need to be subtracted. So that’s a total of 120 that need subtracting, and 600-120 is 480.
Answer:
15. x = 112 degrees
18. x = 120 degrees
Step-by-step explanation:
<u>15.</u>
A triangle's angles always equal 180 degrees so we can find the two unknown angles by subtracting 44 from 180 and then dividing it by 2.
2a + 44 = 180
2a = 136
a = 68
Each unknown angle equals 68 degrees. The line from 44 degrees to x degrees segments a line that has a 180 degree angle so we can subtract 68 from 180 to get x.
x + 68 = 180
x = 112
<u>18.</u>
We can use the same concept here but now every angle equals each other so we can divide 180 by 3 to get the measure of those angles.
3a = 180
a = 60
Now we do the same thing as last time to find x.
x + 60 = 180
x = 120
Answer:
C. 77x⁷ + 78x⁶ - 27x⁵
Step-by-step explanation:
Operation of functions
f(x) g(x)
f(x) • g(x) = (11x³ - 3x²)(7x⁴ + 9x³)
Simplify or expand
(11x³ - 3x²)(7x⁴ + 9x³)
Expand the expression
11x³ × 7x⁴ + 11x³ × 9x³ - 3x² × 7x⁴ - 3x² × 9x³
Multiply
77x⁷ + 99x⁶ - 21x⁶ - 27x⁵
Combine like terms
77x⁷ + 78x⁶ - 27x⁵
Hope this helps and have a nice day
The number 8 is a multiple of 16, 2 x 8 = 16 . And the number 8 + 10 = 18
So, I would think it's 8.
Hope I was able to help you. :-)
