If the simplest quadratic radical √ 3A + 2 and quarter √ 4a-5 are of the same kind, then a=

If the simplest quadratic radical √ 3A + 2 and quarter √ 4a-5 are of the same kind, then a=

Both √ 3A + 2 and quarter √ 4a-5 are the same radical
Radical of the same kind
It's the same in the root
So 3A + 2 = 4a-5
a=7

The 12 questions are: if a + B √ 3a and √ 4A + 3b are the same kind of quadratic radical, then AB =?

a=1,b=1
b+1=2
4a+3b=2a-b+6
Just work it out

A mathematical problem: 3a-b / 3 = 2A + C / 5 = 2B + C / 7, then a: B: C=_____ :_____ :_____
PS: "/" is a fractional line

a：b：c=___ 2__ :_ 3____ :___ 1__

3 H + 2 a = 5.8, 3 A + 2 h = 5.7

3h+2a=5.8(1),3a+2h=5.7(2)
(1) (2), 5A + 5h = 11.5
3A + 3H = 6.9 (3)
(3) (1), a = 1.1
(3) (2), H = 1.2
So h * a = 1.1 * 1.2 = 1.32

Given - 3A + 7b = 4b-3, find the value of a-b

Given 3A + 7b = 4b-3, find the value of a-b

3a+7b=4b-3
3a+7b-4b=-3
3a+3b=-3
a-b=-1

Given that 3A plus 7b = 4b-3, try to find the value of a plus B

3a+7b=4b-3
3a+3b=-3
So a + B = - 1

Given | 3a-4 | + | 4B + 3 | = - | C + 2 |, find the value of a + b-c

|3a-4|+|4b+3|=-|c+2|,
|3a-4|=0；a=3/4
|4b+3|=0; b=-3/4
-|c+2|=0;c=-2
a+b-c=3/4-3/4-(-2)=2,

The fast and slow trains go from a to B at the same time. The fast train runs 54 kilometers per hour and the slow train 48 kilometers per hour. The fast train stops for 3 hours on the way. As a result, the two trains arrive at B at the same time. The distance between a and B is calculated

Let the fast train travel time be x hours, then the slow train travel time be x + 3 hours, & nbsp; & nbsp; & nbsp; 54x = 48 (x + 3) & nbsp; & nbsp; & nbsp; 54x = 48x + 14454x-48x = 48x + 144-48x & nbsp; & nbsp; & nbsp; & nbsp; 6x = 144 & nbsp; & nbsp; 6x △ 6 = 144 △ 6 & nbsp; & nbsp
