Answer: The correct answer is B because 0.7x=210, x=300
Step-by-step explanation:
210= 70% of the total distance to his grandfather's house, lets take that total distance for x.
So if:
210=0.7x
x=210/0.7
x=300
Answer:
Step-by-step explanation:
Please use " ^ " to indicate exponentiation:
A = x^2 + 9x - 36. This factors into A = (x + 12)(x - 3). We can assume that the length of the parallelogram is x + 12 and that the width is x - 3.
Note that if x = 3 the area becomes zero. So: x must be greater than 3, so that the (x - 3) factor is positive.
Example: If x = 4, then the dimensions of the parallelogram are 4 + 12, or 16, and 4 - 3, or 1.
B ∪ (C' ∩ A)
Starting from the inside, C' ∩ A is the intersection of not C, which is everything except the circle C, and A. That's the part I shaded in bright blue.
That's unioned with B, which is just all of the circle B. I shaded the parts of B that I didn't already shade with a grey-blue.
These should all be the same shade; I just made them slightly different for explanation.
Two or more points are said to be collinear if they lie on the same straight line.
Given a straight line XY, with a point P on the straight line between point X and Y, then
XP + PY = XY
From the question, it was given that AB = 7 and BC = 4, so if A, B, C are colinear, then
AB + BC = AC
i.e. 7 + 4 = 11
But, from the equation, AC = 9.
Therefore, points A, B and C are not collinear.
i think i know but looking at peoples answer now i am reconsidering my choices but anyway good luck i think u should use the other guy solution but anyway have a good day :>
