Its an acute angle, im in 6th grade, and your in high school so..... im sorry if i get it wrong, but hey! i tried! lol
Answer:
x^2 (12 x - 5)
Step-by-step explanation:
Simplify the following:
12 x^3 + (2 x x)/2 - 6 x^2
(2 x x)/2 = 2/2×x x = x x:
12 x^3 + x x - 6 x^2
x x = x^2:
12 x^3 + x^2 - 6 x^2
x^2 - 6 x^2 = -5 x^2:
12 x^3 + -5 x^2
Factor x^2 out of 12 x^3 - 5 x^2:
Answer: x^2 (12 x - 5)
To find the mean, you add up all the numbers and divide by the number of numbers in the sequence
28+42+56+70+84+98+112
=490 divide by 7
=70
Answer:
d = 6
Step-by-step explanation:
Given the coordinates A(4, 6) and B(d, 12) with the gradient of AB to be 3
Gradient m = y2-y1/x2-x1
Substitute the given values
3 = 12-6/d-4
3 = 6/d-4
Cross multiply
3(d-4) = 6
Expand
3d - 3(4) = 6
3d - 12 = 6
Add 12 to both sides
3d - 12 + 12 = 6 + 12
3d = 18
Divide both sides by 3
3d/3 = 18/3
d = 6
Hence the value of d is 6
Yes , -2113.15 + (-597.11) + 4121.55 = 1411.29 so the total profit was 1411.29
