Given (a 2 + B 2) 2 - (a 2 + B 2) - 6 = 0, find the value of a 2 + B 2

Let A2 + B2 = y, y2-y-6 = 0, Y1 = 3, y2 = - 2 ∵ A2 + B2 ≥ 0 ∵ A2 + B2 = 3

It is known that the perimeter of a parallelogram is 45cm, and the distance between two groups of opposite sides is 4cm.5cm?

Let the adjacent sides of a parallelogram be a and B respectively
A + B = 45 divided by 2
4a=5b
a=12.5
b=10
So the area of the parallelogram is 10 times 5 = 50

18×1.5-1.7x=13.4．

18×1.5-1.7x=13.4，         27-1.7x=13.4，    27-1.7x+1.7x=13.4+1.7x，       13.4+1.7x=27，  13.4+1.7x-13.4=27-13.4，            1.7x=13.6，       1.7x÷1.7=13.6÷1.7，               x=8．

Given that point P is in the plane of △ ABC, if 2 vector PA + 3 vector Pb + 4 vector PC = 3 vector AB, then the ratio of △ PAB to △ PBC is
After proving that 5 vector PA + 4 vector PC = 0, why is there a complementary between ∠ APB and ∠ CPB?

Because & nbsp; vector 2PA + vector 3PB + vector 4pc = vector 3AB, 2PA + 3PB + 4pc = 3 (pb-pa) & nbsp; 5pa = - 4pc & nbsp; & nbsp; PA = - 4 / 5pc & nbsp; & nbsp; so the ratio of | PA |: | PC | = 4:5 △ PAB to △ PBC is = 4:5 (the same height and different bottom)

Solving equation 1 / 3 + 8x = 8 / 9

1/3 + 8x = 8/9
8x = 8/9-1/3 = 5/9
x= 5/9 ÷ 8 = 5/72

If the variable x y satisfies the constraint {x + y}

Draw the three constraints on the X and Y axes, and then you can make an interval graph. The minimum value must be generated at the vertex. Substitute several vertices to get the minimum value

A = 2 / 1 - (- 1) ^ m (M is a positive integer), and a, B are opposite to each other, B, C are reciprocal, AB + B ^ m - (B-C) ^ 2m
Find AB + B ^ m - (B-C) ^ 2m

A = 2 / 1 - (- 1) ^ m, M is a natural number, because the denominator cannot be 0, then M can only take odd numbers, at this time, a = 1, then B = - 1, C = - 1,
ab+b^m-(b-c)^2m=-1-1-0=-2.
