Factor quadratic trinomials 27x^2-90x+27

igor_vitrenko [27]

27x^2-81x-9x+27 In this case, just in your mind multiply 27 (coefficient of x^2) by the constant value 27(the end value of the quadratic trinomial). Then find factors that give you the value -90 when you add and 729 (27*27) when you multiply.

Factorise the values
27x( x-3)-9(x-3)

Which will give you

(27x-9)(x-3)

Can any one solve this math 7A equation

DiKsa [7]

Answer:

12). Length in the actual will be 6.25x12=75 in

13). Length in the model will be 15/12=1.25 ft

14). depth in the actual will be 32x12=384 cm

15). Width in the actual will be 5.4x12=64.8 ft

16). Diameter in the model will be 21/12=1.75 cm

Step-by-step explanation:

Given table show relation between model and actual prototype.

It is given that the actual prototype is scaled by 12 of the model.

I.e. Model x 12 = Actual.

12).

For mattress,

Length in the model is 6.25 in.

Length in the actual will be 6.25x12=75 in

13).

For corvette,

Length in the actual is 15 ft

Length in the model will be 15/12=1.25 ft

14).

For Water tower,

depth in the model is 32 cm in.

depth in the actual will be 32x12=384 cm

15).

For wingspan,

Width in the model is 5.4 ft

Width in the actual will be 5.4x12=64.8 ft

16).

For Football helmet,

Diameter in the actual is 21cm

Diameter in the model will be 21/12=1.75 cm

Using the conversion of exponent to power, the equivalent expression is given as follows:

$\frac{\sqrt{x}}{\sqrt[4]{y}z^2}$

<h3>How to transform an exponent to a power?</h3>

It happens according to the following rule, with the denominator as the root and the numerator as the exponent:

$a^{\frac{n}{m}} = \sqrt[m]{a^n}$

In this problem, we are given the following expression:

$x^{\frac{1}{2}}y^{-\frac{1}{4}}z^{-2}$

Negative exponents go to the denominator, hence the <em>equivalent expression</em> is given by:

$\frac{\sqrt{x}}{\sqrt[4]{y}z^2}$
