kati45 [8]

$f(x)=x^2-5;\ x\in\{-5;-3;\ 0;\ 1;\ 2\}\\\\f(-5)=(-5)^2-5=25-5=20\\f(-3)=(-3)^2-5=9-5=4\\f(0)=0^2-5=-5\\f(1)=1^2-5=1-5=-4\\f(2)=2^2-5=4-5=-1\\\\Answer:f(-5)=20$

Which simplified expression matches the set of tiles shown?

notka56 [123]

Answer:

The expression - x² - x + 2 and - x² + x + 2 matches the set of tiles

Step-by-step explanation:

Given four expression as :

A ) - x² - x + 2

solving by mid term breaking

Or, - x² - 2 x + x + 2

Or, - x ( x + 2 ) + 1 ( x + 2 )

or, ( x + 2 ) ( - x + 1 )

B ) x² - x + 2

solving by mid term breaking

Or, x² - 2 x + x + 2

or, x ( x - 2 ) + 1 ( x + 2 )

So, the expression will not break

C ) - x² + x + 2

solving by mid term break

Or, - x² + 2 x - x + 2

or, - x ( x - 2 ) - 1 ( x - 2 )

or, ( x - 2 ) ( - x - 1 )

D ) x² + x + 2

solving by mid term break

Or, ) x² + 2 x - x + 2

Or, x ( x + 2 ) - 1 ( x - 2 )

so, The expression will not break

Hence The expression - x² - x + 2 and - x² + x + 2 matches the set of tiles answer

Answer:

$4.5 \times 10^{9}$ tons.

300 times.

Step-by-step explanation:

Last year, the world produced 3.5 billion tons of cement and that amount could increase by a billion tons by the year 2050.

So, the net production of cement by the year 2050 will be (3.5 + 1) = 4.5 billion tons i.e. $4.5 \times 10^{9}$ tons. (Answer)

Now, this amount is larger than $1.5 \times 10^{7}$ by $\frac{4.5 \times 10^{9} }{1.5 \times 10^{7}} = 300$ times. (Answer)
