Answer:
Expand the brackets, and simplify.
(4t - 8/5)-(3-4/3t) = (4t +4/3t) + ( -8/5 - 3) = 5 1/3t - 23/5 = 16/3t - 23/5
5(2t + 1) + (-7t + 28) = 10t + 5 - 7t + 28 = 3t + 33
(-9/2t + 3) + (7/4t + 33) = (-9/2t + 7/4t) + (3 + 33) = -11/4t + 36
3(3t - 4) - (2t + 10) = 9t - 12 - 2t - 10 = 7t - 22
Since the quantity under a square root must be greater than or equal to zero, you would solve for x by subtracting two, to get that 1/3x must be greater than or equal to zero, then divide by 1/3 on both sides to get that x must be greater than or -6, so the last answer is correct
Answer:
f(x) = x² + 7x + 12
Step-by-step explanation:
Given that the zeros are x = - 3 and x = - 4, then the factors are
(x - (- 3)) and (x - (- 4)), that is (x + 3) and (x + 4)
f(x) is the product of the factors, that is
f(x) = (x + 3)(x + 4) ← expand using FOIL
f(x) = x² + 7x + 12
Base=200 and height=100 (km)
This is because think of it like 4s you have two for the base and one for each of the heights sport I can’t really put it into words well :( this is (2:1:1) =4 now divide the 400/4 and you get one hundred now you multiply x2 for the base and x1 for the height. Hope this helps and you have a great day :)
X + 7 > 0 , x > -7
2x -5 > 0 , 2x > 5 , x > 2.5
since that if x is more than 2.5 ,it will be more than -7
so the correct answer is x > 2.5
