Factor completely 4x4 − 24x3 + 36x2.

riadik2000 [5.3K]

The answer: "4x² (x − 3)(x − 3)" ; or, write as: "4x² (x − 3)² " .
_________________________________________________
Explanation:
__________________________________________________

Given: " 4x⁴ − 24x³ + 36x² " ; The least common factor is: 4x² ;

since the least common NUMBER as a factor is "4"; and the least common "variable" as a factor is "x² " ;
_____________________________
4x⁴ − 24x³ + 36x² = 4x² (x² − 6x + 9) ;

Factor the: "(x² − 6x + 9)" ;

(x² − 6x + 9) = (x − 3)(x − 3) ;

Rewrite: "4x² (x − 3)(x − 3)" ; or, write as: "4x² (x − 3)² " .

By what percent will the product of two numbers change, if the first number increases by 70%, while the second number decreases

erica [24]

Answer:

The product of two numbers changes by 2% when the first number increases by 70%, while the second number decreases by 40%.

Step-by-step explanation:

Let first number be x and second number be y .

Then product of x and y = xy ......(1)

Given the first number increases by 70%, while the second number decreases by 40% this means,

x is increased by 70% that is

increased value of x = x + 0.7(x) = 1.7 x

Similarly y is decreases by 40% that is

decreased value of y = y - 0.4(y) = 0.6y

New product will be = (increased value of x )( decreased value of y)

= (1.7x)(0.6y)

=1.02xy

Changed Percentage = $\dfrac{\text{new value - original value}}{{\text{original value}}}\times 100$

Substitute the values, we get,

Changed Percentage = $\frac{1.02xy-xy}{xy}\times 100$

Changed Percentage = $\frac{0.02xy}{xy}\times 100$

Changed Percentage = $0.02\times 100$

Changed Percentage = $2\%$

Thus, the product of two numbers changes by 2% when the first number increases by 70%, while the second number decreases by 40%.

Figure ABC is to be translated to Figure A'B'C' using the rule (x, y) → (x+4, y−6). Which coordinates will best represent point

slavikrds [6]

The rule (x, y) ⇒ (x + 4, y - 6) means to translate the shape four units right and six unit down

Coordinate C (3, 1) ⇒ (3 + 4, 1 - 6) = (7, -5) is the coordinate for C'
