The product of a particular number and a second value, which is given by the sum of 8 and the original number, is 65. What is th

Marina86 [1]

Given:

The product of a particular number is 65.

Second value is given by the sum of 8 and the original number.

To find:

The unknown number.

Solution:

Let x be the unknown number.

Then, second number = x+8

The product of a particular number is 65.

$x\times (x+8)=65$

$x^2+8x=65$

$x^2+8x-65=0$

Splitting the middle term, we get

$x^2+13x-5x-65=0$

$x(x+13)-5(x+13)=0$

$(x-5)(x+13)=0$

Using zero product property, we get

$x-5=0$ and $x+13=0$

$x=5$ and $x=-13$

So, the unknown number is either 5 or -13.

Therefore, the correct option is B.

Answer:

AT = 8 $\sqrt{2}$

Step-by-step explanation:

Using the sine ratio in the right triangle

and sin45° = $\frac{1}{\sqrt{2} }$

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{AB}{AT}$ = $\frac{8}{AT}$

Multiply both sides by AT

AT × sin45° = 8, that is

AT × $\frac{1}{\sqrt{2} }$ = 8

Multiply both sides by $\sqrt{2}$

AT = 8 $\sqrt{2}$
