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

Simplify the square root of 5 times the cube root of 5.

mihalych1998 [28]

Answer:

Option 3 - five to the two thirds power

Step-by-step explanation:

Given : Expression 'the square root of 5 times the cube root of 5'.

To find : Simplify the expression ?

Solution :

Writing expression in numeric form,

The cube root of 5 means $\sqrt[3]{5}$

The square root of 5 times the cube root of 5 means $\sqrt{5\sqrt[3]{5}}$

Now, simplify the expression

$\sqrt{5\sqrt[3]{5}}=\sqrt{5\times (5)^{\frac{1}{3}}}$

$\sqrt{5\sqrt[3]{5}}=\sqrt{(5)^{1+\frac{1}{3}}}$

$\sqrt{5\sqrt[3]{5}}=\sqrt{(5)^{\frac{4}{3}}}$

$\sqrt{5\sqrt[3]{5}}=((5)^{\frac{4}{3}})^{\frac{1}{2}}$

$\sqrt{5\sqrt[3]{5}}=(5)^{\frac{4}{3}\times \frac{1}{2}}$

$\sqrt{5\sqrt[3]{5}}=(5)^{\frac{2}{3}}$

The expression is five to the two thirds power.

Therefore, Option 3 is correct.

Expand and simplify (x+2)(x+1)

galina1969 [7]

So first you would need to FOIL the problem (first-outer-inner-last) so you would multiply x by x and get {x²} then you would multiply x by 1 so you would get just plain {x} then multiply 2 by x so to get {2x} then multiply the last terms 2 and 1 together to get {2} so then put it all together = x² + x + 2x + 2 then you add like terms together so you end up with = x² + 3x + 2 as the answer
