I believe it's 3•3•3-3•3•3•x+3•5•y but I could be wrong :P
Answer:option c
Step-by-step explanation:
Substituting, we have
... f(x+4) = (x+4)² + 8(x+4) +7
... = x² +8x +16 +8x +32 +7
... = x² + 16x + 55
Subtracting the original, we have
... f(x+4) - f(x) = (x² +16x +55) -(x² +8x +7)
... f(x+4) - f(x) = 8x +48
Answer:
8.7
Step-by-step explanation:
formula
d = sqrt(s^2 + s^2 + s^2)
d = sqrt(3*5^2)
d = sqrt(75)
d = 8.7
Where did I get the formula? If the cube sits on one of its faces then the diagonal of that face is sqrt(s^2 + s^2) = sqrt(2s^2)
Now to get the third s^2, you have to realize the the diagonal you calculated in the previous remark is one of the legs for the cube's corner to corner diagonal. The other leg is the height squared which is also s^2.
Answer:
Ramon pays $240.
Step-by-step explanation:
30% of $960 is $288, so Glen pays $288
0.45 = 45%
45% of $960 is $432, so Andre pays $432
30% + 45% = 75% meaning Ramon pays 100% - 75% which is 25%.
25% of $960 is $240. So, Ramon pays $240.
You could also add up the payments of Andre and Glen and subtract that sum from $960 to get the same answer.
