Let alpha beta and gamma are the three zeros of the given polynomial FX and Alpha is equals to a minus b beta is equals to a and gamma is equals to A + B by sum of zeros we have alpha + beta + Gamma is equals to minus minus 3 by 1 so we get 3 a is equals to 3 then a is equals to 1 by this we get alpha × beta × Gama is equals to -1 and putting the value of a in this equation we get -b^2 =-1 thus a is equals to 1 and b is equals to 1

Yes every composite number can be represent as product of prime number . As 16 can be expressed in the form of 2 to the power 4 which is a prime number product and other example 42 which can be expressed in the form form of 2 x 3 x 7 thus this shows that every composite number can be expressed in the form of product of prime numbers

Sia ? 6 years, 6 months ago

Let length of rectangular garden = x metres
and width of rectangular garden = y metres
According to given conditions, perimeter = 36 m
{tex}\frac12{/tex}(2x + 2y) = 36
{tex}\Rightarrow{/tex} x + y = 36 .......(i)
and x = y+4
{tex}\Rightarrow{/tex} x - y =4 ..........(ii)
Adding eq. (i) and (ii),
2x = 40 {tex}\Rightarrow{/tex} x = 20 m
Subtracting eq. (ii) from eq. (i),
2y = 32 {tex}\Rightarrow{/tex} y = 16 m
Hence, length = 20 m and width = 16 m

ANSWER

For what value of x are the points A (_3,12),B (7,6),C (x,9) collinear ?

Sia ? 6 years, 6 months ago

According to the question, A(-3, 12), B(7, 6) and C(x, 9).
(x₁ = -3, y₁= 12), (x₂ = 7, y₂ = 6) and (x₃ = x, y₃ = 9)
The given points A,B,C are collinear. So, area of triangle is zero.
{tex}\Rightarrow{/tex} x₁(y₂ - y₃₎ + x₂(y₃ - y₁)+ x₃(y₁ - y₂)=0
{tex}\Rightarrow{/tex} {tex}(-3)(6 - 9) + 7 (9 - 12) +x(12 - 6) =0{/tex}
{tex}\Rightarrow{/tex} {tex}9 - 21 + 6x = 0{/tex}
{tex}\Rightarrow{/tex} {tex}6x = 12 {/tex}
{tex}\Rightarrow{/tex} {tex}x = 2{/tex}
