2x^2 - 7x + 3 = 02x^2 - 7x = -3X^2 - 7x/2 = -3/2X^2 - 2*1/2*7x/2 = -3/2X^2 - 2*1/2*7x/2 + (7/4)^2 = -3/2 + (7/4)^2(X - 7/4)^2 = -3/2 + 49/16(X - 7/4)^2 = 25/16X - 7/4 = + or -5/4

x = +5/4 + 7/4X = 12/4 =3Also

X = -5/4 + 7/4 = 1/2Hence x = 3 and 1/2

tnx for the help

Let a and b be X and y

option 3 is the correct answer of the given question

(4x-4-3x+9)/((x-3)(x-1))=(5x-10-4x+4)/((x-1)(x-2))(x+5)/(x-3)=(x-6)/(x-2)x*x+3x-10=x*x-9x+1812x=28x=28/12=(7×4)/(3×4)=7/3

Like my answer if you find it useful

thank u mam

So here

complete ans.?

Letx= 0.99999There is only one repeating digit so multiply by 10 we get10x= 9.99999x= 0.99999subtract x now we get9x= 9Divide by 9 we getx= 9/9 = 1

1) 2x^2 - 7x +3 =0 2x^2 - 6x - x + 3 =0 2x(x-3) - 1(x-3) =0 (2x-1)(x-3) = 0 x = 1/2, 3

2) 4x^2 + 4sqroot(3)x + 3 = 0 4x^2 + 2sqroot(3)x + 2sqroot(3)x + 3=0 2x(2x+sqroot(3))+sqroot(3)(2x+ sqroot(3)) =0(2x + sqroot(3)) (2x + sqroot(3)) =0x = - sqroot(3)/2

3(2^x)=192 2^x=192/3 2^x=64 2^x=2^6

=> x=6

how did you complete this some in next to no time?

(x + 1)^2 (x + 4) = (x + 2)^3

(x^2 + 2x + 1)(x + 4) = x^3 + 8 + 6x^2 + 12x

x^3 + 2x^2 + x + 4x^2 + 8x + 4= x^3 + 8 + 6x^2 + 12x

9x + 4 = 12x + 812x - 9x = 4 - 83x = - 4x = - 4/3

first divide 100 by 550. then answer comes 50.5 now multiply the answer by 428 .The answer will come 21614.0

what is the value of sin(π/6)?

sin (π/6) = 1/2.

and what is cos(π/3)?

cos π/3 = 1/2.

value of tan 45?

tan 45° = 1.

Something is symmetrical when it is the same on both sides. A shape has symmetry if a central dividing line (a mirror line) can be drawn on it, to show that both sides of the shape are exactly the same.

symmetrymeans that one shape becomes exactly like another when you move it in some way: turn, flip or slide. For twoobjectsto besymmetrical, they must be the same size and shape, with oneobjecthaving a different orientation from the first. There can also besymmetryin oneobject, such as a face.

median is 22,M-M°=3(M-Me)

An empirical relationship exists between mean, median and mode.

Mode = 3(Mean - Median)18 = 3(24 - Median)Median = 24 - 18/3Median = 24 - 6 = 18

As AB= AC both will have equal angles soangle b= angle c= 55°now angle A= 180-(55+55)= 80°as sum of all the angles is 180°

this questions of answer is [√2]...

the answer is +- √2......

by basic calculation 15 - 69/8 - 15/4 + 13/2 = (120-69-30+52)/8 = 73/8 = 9 1/8

753+607+0+94+36 = 1490

When we add 753+607+0+94+36 we'll get 1490 as the answer

correct answer is 1490 exactly

1490 is the correct and perfect

sorry ma'am try again please
