Factor Completely: x^2-13x-48

salantis [7]

Answer:

Therefore,the required factors are ( x - 16 ) and ( x + 3 )is

Step-by-step explanation:

Given:

$x^{2} -13x-48$

To Factorize:

Solution:

First remove the factor of -48 such that you multiply the two number, the Product should be -48 and the SUM should be -13.

-48 = -16 × 3

Here, -16 and 3 are the two required numbers

now the given expression we will split the middle term and Factorize the given equation.

$x^{2} -13x-48 =x^{2} -16x+3x-48\\\\\\\textrm{removing x common and 3 common we get}\\x^{2} -13x-48=x(x-16)+3(x-16)\\\\x^{2} -13x-48=(x-16)(x-3)$

Therefore,the required factors are ( x - 16 ) and ( x + 3 )

S_A_V [24]

corrected question:

A rectangle and a square have the same perimeter. One side-length of the rectangle is 25% longer than the other. What is the ratio between the areas of the rectangle and the square?

Answer:

ratio of area of recatngle to square= 0.9879

Step-by-step explanation:

perimeter of rectangle = 2(L+B)

perimeter of a square = $4L_(s)$

L=B+0.25B

L=1.25B

$4L_(s)$ = 2(L+B)

$4L_(s)$ = 2(1.25B+B)

$4L_(s)$ = 2(2.25B)

$4L_(s)$ = 4.5B

B= 4/4.5 $L_(s)$

B= 0.889 $L_(s)$ ..........equ1

area of square = $L_(s)^{2}$

area of rectangle = L*B

=1.25B*B= $1.25B^{2}$

ratio of area of recatngle to square = $\frac{1.25B^{2} }{L_{s} ^{2}}$

referring to equ 1

ratio of area of recatngle to square = $\frac{1.25* (0.889L_{s}) ^{2} }{L_{s} ^{2}}$

= $\frac{ 0.9879L_{s} ^{2} }{L_{s} ^{2}}$

ratio of area of recatngle to square= 0.9879
